Health and Safety Guidelines

Warning: cassette probes are sharp and a bio-hazard.

Ensure you are wearing surgical gloves when working with probes and cassettes.

Biohazard When cassettes are not in place on the analyser, ALWAYS PUT A COVER GUARD OVER THE PROBE.

Before putting away for storage always DECONTAMINATE the probe and clean the capillary.

Tools needed:

Syringe with non-return valve and Benson adaptor.
Sample tube with 10% Tween 20.
Some distilled or de-ionised water.

Instructions:

Remove the cassette if necessary (see Cassette removal instructions).

Soak the cassette in non-hypochlorite based disinfectant for the appropriate time (see the cleaning instruction supplied by the cleaning agent manufacturer).

Place the sample tube containing 10% Tween in a suitable rack without its cap.

Picture showing components for this procedure.
The Syringe with non-return valve and Benson adaptor.
Screw the syringe adapter to the capillary connector at the back of the blocked cassette.
Wash Place the probe and cassette into the tube containing 10% Tween with the syringe facing you. Pull on the syringe until a small volume of Tween solution can be seen in the syringe. Leave with Tween inside the capillary for ten minutes. Remove the probe and cassette from the tube, and force out the Tween solution into a waste sink. Move the syringe back and forth, drawing air through the cassette to remove water droplets and moisture. Repeat the above operation using distilled or de-ionised water. Repeat again in 2^nd tube of distilled or de-ionised water. Remove the probe from the water, and move the syringe back and forth, drawing air through the cassette to remove water droplets and moisture. Replace the guard on the probe. Replace the complete cassette in the box provided for storage.
