Pads are supplied sterile, in cartridges of 100. A sterile pad dispenser is supplied for
depositing the pads into the petri-dishes. It is preferable to dispense
pads at the central
laboratory, prior to going to the sampling point; in this way, the dispenser may be kept
attached to a pad cartridge and remain clean and sterile. If it is necessary to dispense pads in
the field, great care must be taken not to
contaminate either the pad dispenser or the
cartridge. As soon as a cartridge is finished, a new one should be attached to the dispenser.
Do not leave the dispenser unattached for any length of time. If no pad dispenser is available
use sterilised forceps.
Before handling a membrane filter with the forceps, the forceps should be flame-sterilised
thusly: hold the forceps tips in a flame for at least 5 seconds, and allow to cool before
handling the membrane.
