Isothermal Continuous Stirred Tank Reactor
Product Code : LSK-TWL-10821
Isothermal Continuous Stirred Tank Reactor (SKU LSK-TWL-10821) is a CSTR set in a constant-temperature water bath, so a non-catalytic homogeneous second-order liquid-phase reaction can be studied at several fixed temperatures. Chemical engineering departments use it for saponification kinetics in the reaction engineering lab. Science Lab Supplies manufactures this reactor at its Saha, Ambala factory (Plot 448, HSIIDC Industrial Area, India) and supplies it direct to universities, polytechnics, tender contractors and distributors.
Specifications
Two feed tanks supply the reactants, which a magnetic drive pump circulates through rotameters with needle valves into a stirred reactor. The reactor sits in a constant-temperature water bath so runs can be made at different temperatures, and samples are taken from its top outlet.

Applications and Experiments for the Isothermal CSTR
The standard experiment is the saponification reaction in the isothermal CSTR: students find the reaction rate constant at one bath temperature, then repeat at others to see how temperature changes it. Perfect mixing means the outlet composition equals the reactor contents, which keeps the calculations simple.
- B.Tech/B.E. chemical engineering reaction engineering lab: saponification kinetics.
- Determining the rate constant and the effect of temperature on it.
- Understanding the key operating variables of a continuous stirred unit operation.
- Diploma chemical engineering practicals on ideal mixed-flow reactors.
Saponification uses an alkali solution, which is corrosive; prepare and handle reactants under supervision with eye and hand protection.
Standard Scope of Supply
The unit is supplied with the stirred reactor, constant-temperature water bath arrangement, two feed tanks, magnetic drive pump and rotameters with needle valves. Instruments, laboratory glassware and chemicals for analysis depend on the system adopted and are not part of the set; any options are listed on the quotation.
Packing, MOQ and Lead Time
Quotations can be prepared for one reactor or a full reaction engineering lab. Each gives packing, delivery time and price for your quantity, and the other reactors in the range can be included so the lab is covered by one engineering lab equipment quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Enquire via the contact page or enquiry cart; see also the lab tender page.
Frequently Asked Questions
What makes this CSTR isothermal?
The reactor is placed in a constant-temperature water bath, so each run is held at one temperature. Changing the bath setting lets students measure the rate constant at several temperatures.
How is feed delivered compared with the standard CSTR?
Here a magnetic drive pump circulates the feed, whereas the standard ambient-temperature CSTR in the range moves its feed with compressed air.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The reactor is made in its own factory in Saha, Ambala, India, and quotations are issued by the factory directly.
What electrical supply is needed?
A single-phase 220 V AC supply rated for 1.5 kW, plus a water supply and a drain near the unit.
