UMB420BT - 33L 'Classic' Sterilizer

Suitable for Wastewater, Food Safety, Veterinary, Microbiology and Biohazard applications.

Astell’s front loading Benchtop autoclaves require no plumbing and operates from a standard single phase power supply. Many customers choose this model not only for its small footprint, but also because it requires no services other than a standard power supply.

This 'Classic' model UMB420BT requires manual water-fill where the user pours the water in the front of the autoclave between cycles to the required level and then during the cycle condensate leaves the vessel via a silicone tube that can be connected to a heat-resistant bottle (available as an optional extra).

This model is suitable for sterilizing:

  • Liquids (media)

  • Lab waste

  • Glassware

  • Lab instruments

This model features

  • A fully programmable touch screen color controller

  • An electro polished stainless steel chamber

  • A base shelf within the chamber

  • An ultra quick Swiftlock door mechanism

  • A self contained design with no installation required - just fill it with water and plug it in and the machine is ready to be used.

  • Angled chamber orientation, ensuring a greatly reduced water requirement every sterilizaion cycle.
