PCD-A-3.5BD / Bowie-Dick Simulation Test for use in Helix-PCD System. Sterilizer monitoring. Laminated self-adhesive strips printed with indicator ink (77 x 6 mm), for Steam sterilization processes. BD cycle: 3,5 min. 134°C. Turns from Blue to Black. ISO 11140-1 Type 2.

Bowie-Dick test simulation for use with Helix-PCD system to control steam sterilization processes (Type 2 Chemical Indicator according to ISO 11140-1:2014). Indicators 100% free of toxic heavy metals.

Instructions for use

1. Insert PCD-A-3.5BD chemical indicator, according to the selected process conditions, within the pin (metal capsule) or slot (plastic capsule) of the screw cap; settle the reactive indicating ink towards the capsule lumen, avoiding folding those areas printed with the reactive indicating ink. IMPORTANT: avoid contact between PCD-A-3.5BD chemical indicator and capsule interior surface, because it can alter the result.

2. Put the capsule cap with moderate pressure.

3. Settle the system into the fabric bag.

4. The entire system should be sterilized in a vacuum chamber under conditions that depend on the chemical indicator to be used:

PCD-A-3.5BD Bowie-Dick cycle 3.5 min. 134 ºC

5. Remove the indicator and evaluate the result. If the 4 bars change from blue to dark grey/black, the result can be considered successful, which means the sterilizer is working correctly. If one bar doesn€™t reach the final color, it means that residual air is present in the sterilizer, therefore a malfunction of the equipment.

The reasons for the failure can be insufficient air removal, leakages and noncondensable gases in steam. We suggest to perform the test once again, before sending the equipment to technical service.
