In your kit you have

Two water test strips.

A strip of something called ‘Parafilm’.

A collection tube.

A sheet of water absorbent foam.

An envelope and labels

Make sure the tube is full of water – we need it right up to the top.

Take the backing paper off the parafilm.

Seal the tube with the parafilm, make sure it’s good and tight.

Put the tube in the plastic bag with the absorbent sheet and seal it.

Put the label on the envelope and post it back to us.
