What this guide is for
Every few weeks a pharmacy department sends us a list of eight or ten machines with nothing beside each name. A mill, a blender, a granulator, a dryer, a tablet press, a coating pan. No capacity, no supply details, no indication of how many students have to run it in one practical session. The list is copied from a syllabus, or from a competitor’s brochure, or from whatever the department bought in 2011.
That list is not a specification. It is a shopping note. The purchase committee turns it into a tender, the tender attracts three quotes that are not comparable, and somebody ends up defending a technical evaluation they cannot actually justify.
This page is written to fix that. It groups pharmacy process equipment by the function it demonstrates, because that is how a department genuinely builds a list, and it tells you what to check before a machine class turns into a line item. It is aimed at B.Pharm, D.Pharm, M.Pharm and pharmaceutical technology departments in India, and at overseas buyers sourcing the same categories.
Two things this page does not do. It does not give you formulation or manufacturing procedures, because that is your faculty’s job and not a supplier’s. And it does not tell you what the Pharmacy Council of India requires in numbers. Pharmacy education in India is regulated by the PCI and colleges are inspected against the current regulations and syllabus, so confirm every quantity, area and provision against the current PCI norms and syllabus for your programme before you commit them to a tender document.
The distinction that decides everything: teaching unit or production unit
This is the spine of the page, so I will put it first and bluntly.
The equipment described here is for education and demonstration. It exists so a group of students can see a unit operation happen, take readings from it, and understand the mechanism. Production equipment and GMP-qualified manufacturing equipment are a different category entirely, with different obligations around qualification, documentation, materials, change control and validation. Nothing on a teaching bench should be presented as validated for commercial pharmaceutical manufacture.
Departments get into trouble when they buy in the wrong category. A machine sized for production is closed, fast, heavy, and built to keep the operator away from the mechanism. That is exactly the opposite of what a teaching lab needs. Students cannot see anything, cannot safely operate it, and the charge quantities are so large that one practical burns through material that should have lasted the semester.
| Attribute | Teaching unit | Production unit |
|---|---|---|
| Purpose | Show the mechanism, generate observable readings | Output at a defined quality and rate |
| Visibility | Viewing windows, transparent shells, guarded but observable drives | Closed, contained, no line of sight to the process |
| Batch size | Small enough that a group can charge, run and discharge inside a period | Sized to a commercial batch |
| Operation | Simple controls, hand or low-speed operation where offered, safe for supervised student use | Trained operators, interlocked, often recipe driven |
| Cleaning | Fast dismantling between student groups, minimum tools | Formal cleaning procedure with documented verification |
| Documentation | Operating manual, factory calibration or test certificate where applicable | Design, installation, operational and performance qualification |
| Failure cost | A practical is delayed | A batch is rejected |
If a tender for a teaching lab is drafted using production language, you will get production quotes and production problems. Keep the wording in the education category and say so explicitly in the scope clause.
The build sequence that actually works
Work in this order. Skipping a step is how departments end up with two machines that do the same thing and none that does the one the examiner asks about.
- Start from the practical list, not the equipment list. Take the current PCI syllabus and the practical schedule for your programme. Write down the experiments, not the machines.
- Group the practicals by function. Size reduction, mixing and blending, granulation and drying, compression, coating, filtration and separation, evaluation and testing. Most departments find that ten or twelve named machines collapse into seven functions.
- Decide how many working groups each function must serve. This is the step everyone skips. It is covered in its own section below.
- Check the room before you check the catalogue. Power phase, drainage, ventilation, bench length. A three phase machine in a single phase room is a crate that sits in a corridor for four months.
- Only then write specifications. Function, observable feature, service requirement, contact material, guarding, supplied accessories. Our guide on writing lab equipment specifications for a tender covers how to phrase this without accidentally naming one brand.
If you are building a fresh lab from an empty room, run this alongside the lab setup timeline and checklist and cost it against the budget planning guide organised by intake. Those two documents answer the questions the principal asks after the technical list is agreed.
Function 1: Size reduction
| Item | Detail |
|---|---|
| Process | Reducing particle size and studying the mechanisms involved: impact, attrition, cutting, compression, and the particle size distribution that results |
| Machine classes | Ball mill, hammer mill, cutter or knife mill, end runner and edge runner mills, laboratory grinders, with a sieve shaker and standard sieve set alongside for the fraction analysis |
| Teaching requirement | The milling chamber must open quickly and, where the design allows, be observable. Charge quantities small enough for a group. Guard interlocks that cut the drive when the chamber is opened. Screen change without a workshop. |
| Specify and check | Supply phase and motor rating, screen or mesh sizes supplied and spares, contact material and finish, noise, dust containment and extraction connection, bench or floor mounting, guard interlock, whether the sieve set is included and to which sieve standard |
Size reduction is the noisiest and dustiest thing in a pharmaceutics lab. It drives the ventilation decision for the whole room, so settle it before you position benches.
Function 2: Mixing and blending
| Item | Detail |
|---|---|
| Process | Achieving and demonstrating blend uniformity, and showing where segregation happens |
| Machine classes | Double cone blender, V or twin shell blender, ribbon blender, planetary mixer, mass mixer, sigma mixer |
| Teaching requirement | A small charge that a group can weigh, load and discharge inside a session. Where a transparent shell is offered, it is worth far more in a classroom than a stainless one, because students can watch segregation instead of being told about it. A timer, so the effect of blend time is measurable. |
| Specify and check | Shell volume and the working fill fraction it is rated for, contact material and internal finish, speed control and timer, discharge arrangement, guard and interlock, cleaning access, spare gaskets |
Function 3: Granulation and drying
| Item | Detail |
|---|---|
| Process | Converting a powder to granules and removing moisture, and observing the relationship between the two |
| Machine classes | Oscillating granulator, rapid mixer granulator, fluidised bed dryer, tray dryer, vacuum tray dryer, laboratory spray dryer for demonstration of drying and particle formation |
| Teaching requirement | A fluidised bed unit is only worth buying for teaching if the bowl can be seen. Insist on a viewing window and readable temperature and airflow indication. Tray dryers should let students see shelf loading and airflow path. Filter bag change must be safe and simple. |
| Specify and check | Heater rating and supply phase, temperature control type and displayed resolution, bowl or tray capacity, air distribution and filtration arrangement, safety cut-outs and over-temperature protection, exhaust routing, whether compressed air is required and at what condition, castors or fixing |
Heater load is the item most often underestimated. Add the dryers together before you talk to the electrician, not after.
Function 4: Tabletting and compression
| Item | Detail |
|---|---|
| Process | Filling, compressing and ejecting, and relating compression conditions to the properties measured later at the test bench |
| Machine classes | Single punch tablet machine, small rotary tablet press, punch and die sets |
| Teaching requirement | A single punch machine with guarded but visible cam action teaches the cycle in one demonstration. Hand wheel operation matters more than anybody expects, because it lets a lecturer walk the class through fill, compression and ejection one step at a time. Output is not the objective and should not be in the specification. |
| Specify and check | Number of stations, punch and die standard and which tooling sets are supplied, tooling spares availability, guarding and interlock, hand operation option, access to fill depth and compression adjustment, bench fixing and vibration, contact material |
Tooling is the recurring cost nobody budgets. Ask what the punch and die standard is, and confirm that replacement sets can be obtained independently of the machine order.
Function 5: Coating
| Item | Detail |
|---|---|
| Process | Applying and drying a coat, and demonstrating the interaction of pan speed, air temperature and application rate |
| Machine classes | Conventional coating pan, perforated coating pan, coating unit with spray system |
| Teaching requirement | Variable pan speed with an indicated value, controlled hot air, and a spray arrangement that behaves at low flow rates. The pan should come off for cleaning without dismantling the drive. |
| Specify and check | Pan diameter, material and mounting angle, drive speed range and control, blower rating and temperature control, exhaust arrangement, compressed air requirement for the spray gun including whether a compressor is in scope, spare nozzles, cleaning access |
Coating is the function where scope gaps hide. The compressor, the exhaust duct and the spray gun consumables are three separate assumptions, and at least one of them is usually not in the quote you are comparing against.
Function 6: Filtration and separation
| Item | Detail |
|---|---|
| Process | Separating solids from liquids and demonstrating filtration mechanisms, sedimentation and centrifugal separation |
| Machine classes | Laboratory filter press, vacuum filtration assemblies, laboratory centrifuge, sedimentation and settling apparatus, membrane filtration assemblies |
| Teaching requirement | A visible flow path. Transparent components where the pressure rating allows. Drainage that does not mean carrying a full tray across the room. Centrifuges used by students need a lid interlock and imbalance protection as a condition of purchase, not an option. |
| Specify and check | Whether the vacuum or pressure source is included, material compatibility with the liquids used, plate and frame or cartridge spares, rotor and tube sets and their availability, lid interlock and imbalance detection, drainage connection, footprint on a wet bench |
Function 7: Evaluation and testing
| Item | Detail |
|---|---|
| Process | Measuring the properties of powders, granules and finished dosage forms, and producing numbers that different student groups can reproduce |
| Machine classes | Tablet hardness tester, friability test apparatus, disintegration test apparatus, dissolution test apparatus, thickness and diameter measurement, bulk and tapped density apparatus, angle of repose apparatus, moisture balance, viscometer |
| Teaching requirement | Readable displays and enough test positions that a batch of groups is not queuing for one instrument. Reproducibility matters more than the last decimal place, because the teaching point is comparison between conditions. |
| Specify and check | Display resolution and units, the published test method the apparatus is built to follow, water bath and temperature control where required, consumables and spare baskets, paddles, tubes and vessels, and the scope of the calibration certificate supplied |
Write the method reference into the specification rather than a brand name. Our note on referencing published standards in lab testing specifications explains how to do that cleanly, and the same discipline applies to pharmacopoeial methods. Then put every one of these instruments on a schedule using the calibration and maintenance schedule guide, because the test bench is what an inspector looks at first.
One boundary worth stating. Pharmacology practical equipment such as rota rod and similar apparatus is teaching and demonstration equipment and sits in a different room with different supervision. Where animal use arises, institutional ethics approval and the applicable regulations govern it and must be confirmed by your institution before anything is ordered.
How many working groups must each machine serve
Decide this per function, not per machine. The arithmetic is simple and almost nobody does it.
| Question | Why it changes the order |
|---|---|
| How many students are in one practical batch | Sets the number of parallel groups |
| How many students per group can actually see the machine | A blender with a solid shell serves fewer eyes than a transparent one |
| How long is one cycle including charging and cleaning | Determines how many groups a single unit can serve in a period |
| Does the experiment need a result within the same session | Dissolution and drying experiments occupy an instrument for a long block |
| Is the machine also used by project and postgraduate students | Research use collides with the undergraduate timetable and usually justifies a second unit or a booking system |
The usual outcome is that you need fewer machine types than the list suggested and more units of two or three of them, typically at the evaluation bench. That is a better use of the same budget than one of everything.
Services and site readiness
The crate arriving before the room is ready is the single most common cause of delay I see. Fix these before the purchase order.
| Service | What to confirm |
|---|---|
| Electrical supply | Which machines are single phase and which are three phase, total heater load for dryers running together, socket type and position, earthing, and an isolator per heavy machine rather than a shared strip |
| Water | Supply point at the wet bench for dissolution baths, cleaning and filtration work, with a sink deep enough to wash a coating pan or a blender shell |
| Drainage | A floor drain in the wet area, and a trap arrangement suitable for the liquids used. Retrofitting drainage into a finished lab is expensive and disruptive |
| Compressed air | Required for spray coating and some fluid bed work. Decide whether the compressor is in the equipment scope or the civil scope, and where the receiver sits given the noise |
| Ventilation and dust extraction | Driven by size reduction and by powder handling generally. Plan extraction at the mill position and general room ventilation, and check the exhaust route out of the building |
| Bench and storage | Run length for the evaluation instruments, a heavy bench or plinth for the tablet press, lockable storage for punches, dies, sieves, spare screens and consumables. Tooling that lives in an open drawer disappears |
| Access | Door width, lift capacity and stair turns for floor-standing units. Measure the route, not just the room |
Documentation for institutional purchase and inspection
A pharmacy purchase passes through more hands than an engineering one, and the file has to survive all of them.
| Document | Why it exists |
|---|---|
| Technical specification sheet per line item | Makes three quotes comparable and defensible at technical evaluation |
| Manufacturer authorisation form | Confirms the bidder is authorised for the offered make. See what an MAF is and when it is asked for |
| Tender document set | Government and aided colleges have a fixed list. The tender documents checklist sets it out |
| Quality certification copies | Certification status of the manufacturer, available on our quality certifications page |
| Calibration or test certificate | Scope matters more than existence. Read the section below |
| Manuals, drawings and catalogue extracts | Filed for the inspection visit and for the next technician. Available from downloads |
| Spares and support commitment | Punches, screens, filter bags, baskets and tubes. See spare parts and after sales support |
| Accreditation lab records | If your institution is preparing a visit, the lab documentation guide for accreditation shows what the file should contain |
On calibration, be precise in your tender wording. We supply factory calibration certificates. We are not ISO/IEC 17025 accredited and we are not NABL accredited, and no manufacturer should let you assume otherwise. If your tender or your accreditation file requires calibration traceable through an accredited laboratory, budget for a third party calibration separately and write it into the scope. Blurring this is how a file fails at audit.
Before you shortlist any supplier, run the same checks you would on a contractor. The manufacturer due diligence guide lists them. If you are buying from outside India, the importer guide and the export documentation guide cover packing, inspection and paperwork.
Cross-checking against your programme lists
This page is organised by function on purpose, but your inspection file is organised by programme. Reconcile the two before submission. The B.Pharm pharmacy lab equipment list and the D.Pharm diploma equipment guide are laid out that way. Departments that also run allied programmes will find the nursing lab list and the chemical engineering unit operations list useful, since unit operations overlap heavily and shared equipment is sometimes the sensible answer.
What gets forgotten until the crate is open
- Spare screens, punches, dies, filter bags, baskets and gaskets, ordered with the machine rather than eighteen months later
- The compressor, when a spray coating unit is bought without one
- A trolley or lifting arrangement for anything that has to move between rooms
- Sieve sets matched to the size reduction work, and a shaker to use them properly
- Weighing capacity at the right resolution near the process bench, not only in the balance room
- Somewhere secure and dry to keep tooling and consumables
- A named person responsible for the maintenance log from day one
None of these are expensive. All of them stall a practical schedule.
Where we sit in this
We have manufactured and exported teaching and process equipment from our own works in Ambala, Haryana since 1993, and we supply to more than sixty countries. Our quality management system is certified to ISO 9001:2015, and CE conformity documentation is available for applicable models. Everything described on this page belongs to the education and demonstration category. GMP-qualified production equipment is a separate category with obligations we do not claim.
Pricing is quote based, because the sensible price depends on the batch sizes, the working group count and the accessories your practical schedule actually needs. That is also why the useful conversation starts with your practical list rather than with a model number.
Send us the syllabus practical list, your student batch size and a photograph or sketch of the room with the available supply noted, and we will come back with a function-by-function proposal you can put in front of a purchase committee. Contact our team with those three things and the first draft is usually enough to start the internal approval.
One honest ask
We don't gate anything on this site. You just read the whole thing free. If it was useful, leave your email and two things happen: we send you this page as a plain-text block you can paste into a tender file or an internal email, and we notify you the next time we publish a buyer tool like this one. Nothing else. No drip sequence, no sales calls booked without asking.
