RTD Studies in CSTR
Product Code : LSK-TWL-10799
RTD Studies in CSTR (SKU LSK-TWL-10799) lets students measure the residence time distribution of a continuously stirred tank reactor with a pulse tracer and compare it with ideal back-mixed flow. It is used in chemical reaction engineering practicals for B.Tech/B.E. and diploma students. Science Lab Supplies, a laboratory equipment manufacturer in India, builds it at Plot 448, HSIIDC Industrial Area, Saha, Ambala, and supplies it direct to colleges, tender contractors and distributors.
Specifications
Water from a single feed tank is circulated to a stainless steel stirred tank reactor by a magnetic drive pump. A needle valve sets the flow, a rotameter measures it, and a syringe doses the tracer into the reactor. The unit runs on a 1 phase, 220 V AC supply.

Applications and Experiments for the RTD Studies in CSTR
The set-up shows how real stirred vessels deviate from the ideal mixed-flow model through channelling, recycling or stagnant pockets. Students inject a pulse of tracer, follow the outlet concentration and plot the RTD curve, a standard reaction engineering practical in chemical engineering degree and diploma programmes.
- B.Tech/B.E. chemical engineering: plotting the RTD curve of a CSTR using a pulse tracer.
- Determining the dispersion and comparing the measured curve with ideal mixed flow.
- Diploma practicals on the stimulus-response technique for non-ideal reactors.
- Process-plant training: operating the pump, needle valve and rotameter.
Standard Scope of Supply
The set-up is supplied with the feed tank, the stainless steel stirred tank reactor, the magnetic drive pump, the needle valve and rotameter, and a syringe for tracer dosing. Instruments, laboratory glassware and chemicals for analysing the samples are not included, as they follow the analysis system your laboratory uses.

Frequently Asked Questions
What experiments can be done on the RTD Studies in CSTR?
The listed experiments are plotting the RTD curve of the CSTR with a pulse tracer and determining the dispersion, which shows how far the tank departs from ideal mixing.
What power supply does the unit need?
It needs a 1 phase, 220 V AC electricity supply rated 0.5 kW, together with a water supply and a drain, so plan a bench near a socket and a sink.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The unit is made at its own factory in Saha, Ambala, India, and quotations come directly from the factory.
How is this different from the packed bed RTD set-up?
This unit studies a stirred tank, where flow is close to fully mixed; the packed bed version uses a Raschig ring column that approximates plug flow.
Related Reactor Engineering Trainers
Pairing the stirred tank tracer study with these four units gives students both ends of the mixing spectrum, from near plug flow in packed and tubular reactors to fully mixed tanks, plus steady-state conversion experiments on the same reactor types.
