Steam autoclave control tests

Perfecto Bowie & Dick Test

The essential daily test for verifying an autoclave’s correct functionality. It checks the efficiency of air removal and steam penetration, ensuring the safety and effectiveness of every sterilisation cycle.

  • Autoclave effectiveness control
  • Steam penetration control
  • Clear and immediate results
  • Compliant with the current standards

Safety and regulatory compliance

Performing the test daily is essential for ensuring compliance with the safety regulations (e.g. Legislative Decree 81/08) and for ensuring the protection of patients and operators.

Rapid detection of malfunctions

A non-compliant result immediately highlights issues in the autoclave (e.g. steam quality, leaks), allowing the use of an inefficient machine and incorrectly sterilised instruments to be avoided.

Traceability and record-keeping

The indicator sheet can be easily stored in sterilisation records, providing documented evidence of correct equipment maintenance and functionality.

The daily test that certifies your sterilisation process

The Perfecto Bowie & Dick test is an indispensable device for the daily verification of steam autoclave functionality. This single-use test pack simulates a porous load, and allows for the verification of the preliminary vacuum and the steam’s ability to penetrate evenly throughout the chamber. The change of the internal indicator’s colour provides clear and immediate visual confirmation of the autoclave’s proper functionality, ensuring that effective sterilisation conditions are met. This is a crucial step in guaranteeing the safety of every instrument to be used.

WHY IT IS ESSENTIAL

Sterilisation safety is not optional

Sterilisation is a vital process for ensuring the safety of patients and staff. Regulations such as Italian Legislative Decree 81/08 require employers to take all necessary measures to guarantee safe procedures. The Bowie & Dick test is one of the essential checks for verifying autoclave functionality. A negative result could indicate serious issues, such as poor steam quality, residual air pockets or leaks in the vacuum system. Performing this test prior to sterilisation is the most effective way to validate the process and ensure complete safety.

USER GUIDE

How to perform the test correctly

For accurate results, the test should be performed at the start of the day with the autoclave empty and cold. Place the test pack alone at the centre of the sterilisation chamber’s lowest shelf. Select and start the dedicated “Bowie & Dick” cycle (usually 134°C for 3.5 minutes). When complete, remove the indicator sheet: a uniform and consistent colour change indicates that the test was successful. Spots or areas of different colour indicate a malfunction, requiring technical intervention before the autoclave can be used.
