Helix Test System

The Helix Test System by Interster is the ideal process challenge device for performing “worst case” sterilisation scenarios. Suitable for every sterilisation process in a loaded autoclave, it ensures maximum steam penetration for hollow instruments or those with small lumina. The Helix strips comply with EN 867-5 and EN-ISO 11140-1 (Type 2) and feature a clear, even colour change for easy interpretation. The non-toxic ink prevents instrument damage, and the slice strip on the back allows for easy storage in logs or registration cards. Available in 3.5-minute, 5.3-minute, and 7-minute variants, the Helix Test System meets diverse international testing requirements.
