The Getinge Assured Bowie-Dick Test Card TT is a top-of-the-line product designed for daily monitoring of small pre-vacuum type B steam sterilizers operating at 134°C. This card is specially packaged and designed to meet ISO 11140-6 requirements. It is a replacement for the now obsolete Green Card Test. The Test Card TT is specifically packaged for daily monitoring and detection of residual air, which can inhibit pre-vacuum steam sterilization. The special pouch packaging prevents the indicator card from being exposed to excessively wet steam conditions that are sometimes present in small steam sterilizers.
