Loggershop and Wessex Power are proud to have contributed to the Fall 2019 issue of the MadgeTech Connections magazine. This issue focuses on the importance of autoclave temperature validation and how to effectively sterilize steam.

We highlight a selection of MadgeTech temperature and pressure data loggers available at Loggershop that are renowned for overcoming barriers within autoclave monitoring. Read our helpful summary below comprising of the best bits from the magazine:

Top 5 Reasons Why Autoclave Steam Sterilization Fails

This section discusses the importance of autoclave validation and why steam sterilization can sometimes fail. Autoclaves are part of regular practice in a variety of industries, from healthcare to medical laboratory. However, there are some variables that can cause steam sterilization to go wrong, including:

  • Putting autoclave contents on the incorrect cycle: Sometimes autoclave contents need to be sterilized at different times. This is because different types of objects need to be sterilized on different cycles. Therefore, putting objects of various types on the same autoclave cycle can result in some contents not being fully sterilized.
  • Improper loading or packing methods: Autoclaves usually have specific requirements in terms of how they should be loaded before sterilisation. As well as this, certain tools need packing or wrapping before sterilization. If any packing, wrapping or loading is performed incorrectly, this can negatively impact the quality of the sterilization process.
  • Inadequate steam quality: If your steam quality is poor, you may not be achieving the level of sterilization that is deemed compliant. Inadequate steam quality can be due to the water content within the steam being too high, or because steam has overheated and causing all liquid to vaporise.
  • Vacuum failure: A vacuum cycle is used for specifically small or intricately shaped contents, where steam can reach every nook and cranny. If this vacuum fails, this puts your contents at risk of being ineffectively sterilised.
  • Incorrect temperatures: If your autoclave does not reach the correct temperature, the contents will not be sterilized to an adequate level. This could mean that you fail to meet government compliance. Facilities can ensure their autoclaves are reaching the appropriate temperature for sterilization with a temperature data logger.
