What’s that powdery substance or pink stuff inside the container that came with my kit?

There’ll either be a powdery substance or a pink fluffy material in the white jar you receive. Both are absorbent materials. In the off-chance that there’s a spill during transport, it prevents the reagent from doing any damage to its surroundings. We include it as an extra precaution. You can also conduct your tests over the jar so that if a drop misses the testing vial, the reagent will land onto the absorbent material.
