SafeSeal(R) Quattro sterilisation pouches are made from high-quality porous medical paper and mechanically sealed with TruePress(TM) technology. The perforated fold facilitates precise folding of a wide self-adhesive strip to form an airtight seal. Internal and external multiparameter process indicators for steam sterilisation respond to three variables: time, temperature and saturated steam. The multiparameter process indicators printed directly on the pouch confirm sterilisation parameters. The blue-tinted film makes it easy to view instruments and detect punctures or tears. A convenient thumb notch makes it easy to open the pouch without contaminating the contents.

Available in:

89 x 229mm - hand tool & equipment (nipper, clipper etc.)

254 x 356mm - multiple tools & equipment (trays, dishes, etc.)

Colour Chart Guide

Below is a colour change guide that should help in the interpretation of the colour change that occurs when the pouches are processed in an autoclave, or ethylene oxide sterilisation chamber.

Caution: the chemical indicators are only used as a sterilisation process indicator. The indicators should be used in conjunction with biological indicators (spore strips) to ensure the devices within the pouches are sterile. Each strip has a starting colour and a finishing colour. Ideally, the indicator should change from the first box to the last box, but this is often not the case due to the large variation in sterilisation chambers. Therefore, an acceptable range of colour changes is recommended as below:

FAQs

What is a normal process of sterilisation?

A normal process of sterilisation implies 3 stages: The pre-conditioning time, the sterilisation exposure time, and the cooldown time (also commonly referred to as "drying time").

At 132/134 degrees C, the sterilisation exposure time is usually 4 minutes (although can be longer for special applications). At this temperature, we know...
