Isothermal Plug Flow Reactor Manufacturer,Supplier and Exporter in India
Product Code : EL-TWL-9144
Jlab Export is a leading Isothermal Plug Flow Reactor Manufacturer,and suppliers in India
Fluid moves through a plug flow reactor in order, with no element overtaking or mixing with the one ahead or behind. In this set-up the stainless steel reactor is held at a chosen temperature by a heated water bath. Air pressure on the two feed tanks sends each reactant through a pre-calibrated rotameter. The product runs on to a receiver tank.

Practicals at Several Temperatures
The aim set for students is the reaction rate constant k at each bath temperature, usually for the saponification of ethyl acetate with sodium hydroxide. With both feeds set and the bath steady, students take a fixed volume of outlet liquid. They measure it with a one-mark pipette from the Bulb Pipettes, Class B Soda Glass, One Mark JLab and run it into excess standard acid. Back titration gives the conversion X. Students confirm the bath reading with a Digital Stem Thermometer before each run.
For equal feed concentrations the plug flow design equation gives k = X / (C_A0 τ (1 - X)), with τ the reactor volume over the total flow. Runs at several flows confirm that k stays the same at one temperature. Moving the bath to new settings then gives the temperature dependence of k.
Frequently Asked Questions
What is the difference between isothermal and adiabatic operation?
In isothermal operation heat passes to or from the surroundings, so the reactor stays at one temperature and k is the same along its length. In adiabatic operation no heat crosses the wall and the temperature changes as the reaction goes on. This unit uses a water bath for isothermal runs.
How do I get the activation energy from my runs?
Work out k at three or four bath settings with the same flows. The Arrhenius plot of ln k against the reciprocal of absolute temperature has a slope equal to -E/R. Multiplying that slope by minus the gas constant gives E.
Why are the rotameters pre-calibrated?
Each reading already corresponds to a known liquid flow, so the two feeds can be set straight away without a timed collection first. A quick timed fill of a measuring vessel at the start of the day is still a sensible check.
What does the Cr/Al sensor do?
Cr/Al is a chromel-alumel junction, the same K type as the Type K Thermocouple. It feeds the digital indicator cum controller, which reads 0–200 °C and switches the nichrome heater to hold the bath at its set point.
Why is there a product receiver?
All the outlet liquid from a run collects in one stainless steel tank. The spent mixture can then be neutralised and disposed of together at the end of the session.
