Frequently asked questions

When do I need a dechlorination tablet?
Whenever a chlorine residual would bleach or distort the test you are about to run, which is common on strongly chlorinated potable or pool water.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
