Sterilizer tests

Helix test

CAUTION! Follow local/national guidelines on the frequency of testing.

PURPOSE OF THE TEST

The test is used to validate the sterilizer performance for hollow items.

DESCRIPTION

It consists of a 1.5 m long tube open on one side and closed with a capsule containing a chemical indicator strip on the other side. The colour
assumed by this indicator strip at the end of the sterilization cycle gives the result of the test.

CARRY OUT THE TEST (IN ACCORDANCE WITH EN13060)

Empty the sterilizer chamber to ensure no load is present. Do not remove the
standard chamber accessories mounted (e.g. chamber rack and trays).

Unscrew the tube capsule and place inside it an indicator strip according to the
instructions of the test manufacturer.

Screw the capsule.
