2. FILTERS

2.1 Glass Fibre (GFA)

2.2 Membrane (MCE)

Caution !

All filters are delicate, especially GFA and must always be

handled with flat tipped tweezers, never by hand.

It is important to remember to remove the backing paper

from a membrane type filter before sampling. The

backing is usually blue.
