RTD Studies in Packed Bed
Product Code : LSK-TWL-10798
RTD Studies in Packed Bed (SKU LSK-TWL-10798) is a bench set-up for measuring the residence time distribution of liquid in a glass column packed with Raschig rings, showing how a real packed bed departs from ideal plug flow. It serves reaction engineering labs in degree and diploma chemical engineering courses. Science Lab Supplies manufactures it at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it direct to colleges, polytechnics, tender contractors and distributors.
Specifications
The set-up is built around a vertical glass column filled with Raschig rings. Liquid enters through a bottom distributor, flow is set with a needle valve and read on a rotameter, tracer is injected at the lower end, and samples are taken periodically from the top outlet.

Applications and Experiments for the RTD Studies in Packed Bed
The apparatus is used to record the response of a packed bed to a tracer pulse, plot its RTD curve and work out the dispersion number that describes axial mixing. It fits the chemical reaction engineering practicals of B.Tech/B.E. chemical engineering and the reactor topics of polytechnic diploma courses.
- B.Tech/B.E. chemical engineering: plotting the RTD curve of a packed bed that approximates plug flow.
- Calculating the dispersion number from the tracer response.
- Diploma practicals on non-ideal flow, channelling and stagnant zones.
- Process-technician training in rotameter flow setting and timed sampling.
Standard Scope of Supply
Each unit comprises the glass column packed with Raschig rings, the bottom liquid distributor, the rotameter with needle valve, the tracer injection arrangement and the top sampling outlet. Instruments, laboratory glassware and chemicals for analysing the samples are not included, as they depend on the analysis system your laboratory adopts.
Packing, MOQ and Lead Time
You can request a quotation for one set-up or a complete reaction engineering laboratory; each Science Lab Supplies quotation states the packing, delivery time and price for that quantity. Colleges sourcing engineering lab equipment in India can add the companion reactor units to the same quotation.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Send your requirement through the contact page or the enquiry cart, and see the lab tender page for tender supply.
Frequently Asked Questions
What does the RTD Studies in Packed Bed set-up measure?
It measures how long liquid elements stay in the packed column. The tracer response at the top outlet gives the RTD curve, from which students find the mean residence time and the dispersion number.
Are analysis instruments and chemicals included?
No. The instruments, glassware and chemicals for sample analysis depend on the tracer and analysis system the laboratory adopts, so they are arranged separately.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The set-up is built at its own factory in Saha, Ambala, India, and quotations come directly from the factory.
What utilities does the unit need?
The specification lists a water supply and a drain as the utilities required, so place the unit near a laboratory drain point.
