95 - 135 Litre Top Loading Autoclave

The 95 - 135 litre toploading autoclave range offers increased chamber sizes compared to the 'Compact' units, as well as featuring advanced options not available on smaller sized autoclaves, including Heated Jackets, Integral Steam Generators, Simple/Advanced Vacuum and Cooling options.

These options enable a top loading sterilizer to be tailored to the needs of the customer by speeding up cooling, dealing with liquids, porous-type loads and allowing a wider range of items to be efficiently processed.

Astell autoclaves are used in scientific research worldwide.  View selected peer-reviewed research papers that reference their use in experimental methodology.

Range Classification


The option to purchase additional features means that this range is highly versatile and can be used for a large range of sterilizing situations. As standard, the autoclave is fitted with heaters in the base of the chamber and can be used for sterilizing liquids (media), discard, glassware and other instruments. Selecting the optional Integral Steam Generator will help to improve efficiency and cycle times.

Direct steam models are available at no extra cost.

Astell can custom build the Top Loading range to your specifications.
