Colr

Your lab professor,
in your pocket.

Do any practical on your own — even if you've never held a micropipette. No more waiting for sir or ma'am to check every step.

One step at a time

Every practical broken into simple slides. Tick, and the next one comes up.

Maths made easy

Don't know how to make 1 N HCl? Colr shows the formula — and the answer if you want.

Why every reagent

What NaCl, EDTA or CTAB actually does — exactly what CSIR-NET and vivas ask.
