Description

Contains: 1 x TST Helix, 250 x TST Strips

The Browne TST Helix is a hollow load process challenge device. The TST Helix is designed for testing the air removal (steam penetration) capability of small Type B steam sterilisers. The chemical indicator located in the capsule will show a defined colour change from yellow to dark blue/purple when exposed to a specific combination of Team, Steam and Temperature. When all the air has been removed from the steriliser chamber, steam will penetrate through the helix and the indicator will show a uniform colour change. If air or non-condensable gases are present the indicator will show distinct yellow markings.

Should you use in any other steriliser or with any other type of indicator, it may give dangerously misleading results.

The TST Helix has a limited life, when the 250 indicators have been used the device must be replaced.
