Clock Reaction Demonstration Manufacturer,Supplier and Exporter in India
Product Code : EL-DE-6738
Jlab Export is a leading Clock Reaction Demonstration Manufacturer,and suppliers in India
Clock Reaction Demonstration (code EL-DE-6738) is a kit for a modified clock reaction: two colourless solutions are mixed and, after a few seconds, the mixture suddenly turns dark blue. Warming the solution makes the change come sooner, and diluting one solution delays it. This version uses safer chemicals than the typical clock reaction. JLab manufactures it in Ambala, India.

What Is the Clock Reaction Demonstration Used For?
It is a classic way to teach reaction rates. Students time how long the blue colour takes to appear, then repeat the run warmer or with one solution diluted and compare the times, giving real data on the effect of temperature and concentration. It suits secondary chemistry practical work and introductory kinetics at college. Use clean glassware for every run, because traces of the previous mixture can upset the timing.
Frequently Asked Questions
What colour change should the class expect?
Two colourless solutions are mixed, nothing seems to happen for a few seconds, and then the whole mixture turns dark blue at once.
How do temperature and concentration change the result?
A warmer solution reacts more rapidly, so the blue appears sooner; diluting one of the solutions slows the reaction and lengthens the wait.
How is this different from the typical clock reaction?
It is a modified version that uses safer chemicals while still showing the same sudden colour change and the same effects of temperature and concentration.
Who manufactures the Clock Reaction Demonstration?
JLab, the brand of Jain Laboratory Instruments Pvt Ltd, manufactures it in Ambala, Haryana, and sells it direct to schools, colleges and science dealers.
OEM Manufacturer
Every kit is made by Jain Laboratory Instruments Pvt Ltd, the company that trades as JLab, incorporated in 2017 and based in Ambala, Haryana. Schools and importers who buy from the maker receive repeat batches of the same kit, which helps keep class results comparable from one year to the next. JLab exports worldwide; destinations include Kuwait in the Middle East, the Philippines in Southeast Asia, the Netherlands in Western Europe and Italy in Southern Europe.
