Quick answer. Settle the chemicals, the emergency services and the waste route before you choose a reactor. Every CRELE unit is a chemical plant in miniature, and a laboratory with the rigs but not the provisions will not run one experiment. Ask for each experiment's chemical list with quantities per run and confirm the reagents can be bought or imported where you are, because a reactor you cannot charge is furniture. Provide fume extraction ducted outside, an eyewash and drench shower, and a properly sized spill kit, and agree in writing where each vessel's contents go after every run. Then choose reactors by syllabus.
About seventy units, coded CRELE-0001 onwards - the second largest listing in this group. Reactors: batch, adiabatic batch, enzyme, combined flow, a cascade, emulsion and condensation polymerization reactors, a trickle bed and chemical reactor training equipment. Mass transfer and separation: absorption in a packed column, a gas absorption column, solid-liquid extraction, a rapid extractor, sedimentation studies, distillation and a double water distiller, and reverse osmosis with ultrafiltration. Transport and hydrodynamics: fluidisation and fluid bed heat transfer, hydrodynamics of a trickle bed, and residence time distribution studies in a packed bed. Support equipment: interchangeable glassware, a chiller water bath, a laboratory pasteuriser and a liquid chromatograph.
Three notes on our catalogue text. One record is listed only as "Cover All", which does not identify a product - ask us what it is before ordering it. One reactor record has "batch" misspelled and one is listed simply as "Cascade". One code is missing from the sequence, and the liquid chromatograph is an analytical instrument rather than reaction engineering equipment - chromatography is covered in our gas chromatography listing. Quote the code and the full product name together and ask for a specification sheet for anything whose name does not describe a piece of equipment.
This is the one range in the catalogue where the equipment is the smaller half of what you have to provide. Every unit here is a chemical plant in miniature, and a reaction engineering laboratory that has the rigs but not the provisions below will not run a single experiment. Settle all three before the order, not after delivery.
| Provision | What it means in practice |
|---|---|
| Extraction and emergency services | Fume extraction over any unit handling a volatile or a reaction that evolves gas, ducted outside rather than recirculating; an eyewash and a drench shower within a few seconds walk, tested and recorded; a spill kit sized for the largest vessel in the room; and a fire extinguisher suited to the chemicals in use |
| Reagent supply and importability | Every experiment has a chemical list, and some reagents are controlled, some cannot be imported and some have a short shelf life. Ask us for the chemical list of each experiment with the quantities per run, then check availability locally before buying the rig - a reactor you cannot charge is furniture |
| A waste route | Decide, in writing and before delivery, where the contents of each vessel go at the end of each run. Acidic and alkaline effluent usually needs neutralising; organics, catalysts and heavy metals need collection and a licensed route; and nothing goes to the drain by default. The waste route is a condition of operating the laboratory, not an afterthought |
Ask us for the safety data sheet of any chemical supplied with equipment, and confirm it can be imported into your country before the shipment is made up.
The reactors are the heart of the range, and they are not interchangeable - each exists to show something the others cannot. Choose by the syllabus rather than by price.
The batch reactor gives conversion against time, which is where kinetics is learned: rate constants, order of reaction and the Arrhenius dependence if the temperature can be set and held. Ask how temperature is controlled and how samples are drawn and quenched, because a sample that keeps reacting on its way to the analysis gives a kinetics curve that is wrong in a consistent and convincing way.
The continuous stirred tank and the cascade give steady-state conversion against residence time, and the cascade - tanks in series - shows a class the one result that reconciles the two idealisations: as the number of tanks increases, a cascade approaches plug flow. That is worth a rig on its own.
The tubular and trickle bed reactors introduce the real behaviour of flow through a bed: axial dispersion, channelling, and wetting in a trickle bed. The hydrodynamics unit for the trickle bed is the companion piece and is what makes the reactor results interpretable.
The adiabatic batch reactor needs a paragraph of its own. It is deliberately insulated so that the heat of reaction raises the temperature, which is exactly how a runaway reaction happens in industry, and that is the lesson. So the safety specification matters more here than on anything else in the listing. Ask: what reaction is intended and what its heat of reaction is; what the maximum temperature and pressure of the vessel are and what relief device is fitted and where it discharges; whether there is a temperature trip independent of the controller; and whether the reaction can be stopped quickly - a quench, a dump or a cooling path. Never run an unfamiliar exothermic reaction in an adiabatic rig without a written assessment of the worst case, and never scale up an exercise because "it worked at the smaller size".
The polymerization reactors bring their own two issues: polymerizations are exothermic, often strongly so, and the contents become viscous as they go, which changes both mixing and heat transfer. Ask about the stirrer motor torque and whether it will cope at the end of the run, how the vessel is cleaned afterwards, and what the monomer is - monomers are typically flammable, are supplied with an inhibitor and should be stored and used accordingly.
The residence time distribution study is among the best value items here, because it teaches the difference between what a reactor is supposed to do and what it actually does - short-circuiting, dead zones and channelling - with nothing more than a tracer and a detector. The whole experiment turns on those two things, so ask: what tracer is used and how is it detected - a salt with a conductivity cell, a dye with a colorimeter, or something else; how the pulse or step is injected reproducibly; how the signal is logged, since the shape of the curve is the result and reading it by hand loses the detail; and what the tracer costs and whether it can be discharged.
Much of this equipment is borosilicate glass, which is why a record for interchangeable glassware exists. Two practical points: ask for a spares list and prices for every glass component before you buy the rig, because a laboratory with a broken condenser and a three-month lead time has lost a term; and ask what shielding is provided where glass is under vacuum, under pressure or heated, because glass fails suddenly.
Services: cooling water supply and drain for condensers and the chiller bath, and the water quantity per run, which on a distillation rig is substantial; electrical supply with earth-leakage protection, since water and heaters share these benches; compressed air or vacuum where a unit needs it; and bench space that allows a unit to be reached from both sides. Ask also for the warm-up or settling time of each unit, because a distillation column that takes an hour to reach steady operation will not fit a short practical slot.
Two units in the listing serve a different syllabus and are worth separating in your thinking: the laboratory pasteuriser and the reverse osmosis with ultrafiltration unit are food technology and water treatment equipment rather than reaction engineering, and they are excellent for those subjects. Say which programme you are equipping and we will quote accordingly.
For each unit: the experiments it is designed to deliver and the chemical list for each, with quantities per run; vessel material, capacity, maximum temperature and pressure, and relief and trip devices; how temperature is controlled and recorded; sampling arrangement and whether samples can be quenched; stirrer type, speed range and torque; what is instrumented, with accuracies, and whether data can be logged and exported; glass spares list with prices and lead times; services required - cooling water with flow, drain, power, air, vacuum, extraction volume; waste produced per run and its expected route; safety data sheets for anything supplied; bench space, mass and access; nominal voltage, frequency and plug pattern; and the warranty, commissioning, training and local service position. For any certification stated here, contact us for the latest copies of the relevant certificates before you tender on it.
Related ranges: process control and instrumentation for the control of these processes, heat transfer lab apparatus for the thermal fundamentals, hydraulics and fluid mechanics trainers for flow measurement, refrigeration and air conditioning for cooling plant, and gas chromatography for analysis. The full set is listed under engineering apparatus. For a quotation, send us your syllabus experiment list and tell us the destination country, the services available in the room and what your institution is permitted to store and discharge - those answers decide which of these seventy units you can actually run.
Three provisions. First, extraction and emergency services: fume extraction ducted outside, not recirculating, over any unit handling a volatile or a gas-evolving reaction; an eyewash and drench shower a few seconds' walk away, tested and recorded; a spill kit sized for the largest vessel; and an extinguisher suited to the chemicals. Second, reagent supply: some reagents are controlled, some cannot be imported and some have a short shelf life, so check them locally first. Third, a written waste route: acid and alkaline effluent usually needs neutralising, organics, catalysts and heavy metals need collection, and nothing goes to the drain by default.
Choose by syllabus, because they are not interchangeable. The batch reactor gives conversion against time, which is where kinetics is learned: rate constants, order of reaction and the Arrhenius dependence if temperature can be set and held. Ask how samples are drawn and quenched, since a sample that keeps reacting gives a consistently wrong curve. The continuous stirred tank and the cascade give steady-state conversion against residence time, and the cascade shows that tanks in series approach plug flow as their number rises. The trickle bed reactor shows dispersion, channelling and wetting, and its hydrodynamics unit makes those results interpretable.
More than anything else in the listing, because it is deliberately insulated so the heat of reaction raises the temperature, which is exactly how a runaway happens in industry. Ask what reaction is intended and its heat of reaction; the vessel's maximum temperature and pressure; what relief device is fitted and where it discharges; whether a temperature trip works independently of the controller; and whether the reaction can be stopped quickly by a quench, a dump or a cooling path. Never run an unfamiliar exothermic reaction in it without a written worst-case assessment, and never scale an exercise up because it worked at a smaller size.
The emulsion and condensation polymerization reactors raise two issues. Polymerizations are exothermic, often strongly so, and the contents become viscous as the run goes on, which changes both mixing and heat transfer. Ask what torque the stirrer motor has and whether it will cope at the end of the run, not just the start, and how the vessel is cleaned afterwards. Ask also what monomer the exercise uses: monomers are typically flammable and are supplied with an inhibitor, so they need to be stored and handled accordingly, and that belongs in your chemical list and storage plan.
Because it teaches a large idea with a small rig: the difference between what a reactor is supposed to do and what it actually does, through short-circuiting, dead zones and channelling, using nothing more than a tracer and a detector. Everything turns on those two, so ask what tracer is used and how it is detected, for example a salt with a conductivity cell or a dye with a colorimeter; how the pulse or step is injected reproducibly; and how the signal is logged, since the shape of the curve is the result and reading it by hand loses detail. Ask whether the tracer can be discharged.
Spares and shielding. Much of this equipment is borosilicate glass, so ask for a spares list with lead times for every glass component before you buy, because a broken condenser with a long lead time can cost a term. Ask what shielding is provided where glass is under vacuum, under pressure or heated, since glass fails suddenly. Then the services: cooling water supply and drain with the quantity per run, which is substantial on distillation; power with earth-leakage protection; compressed air or vacuum where needed; and bench access from both sides. Ask each unit's settling time, too.
