Fermentador KLF

A remarkable bioreactor

The KLF is the only in-situ sterilizable glass benchtop fermenter on the market.

During sterilization, the medium is stirred and the temperature is continuously measured and recorded – comparable to the processes in larger steel fermenters.

The steam-sterilizable bottom drain valve ensures complete emptying and can also be used for sampling. As optional feature, the KLF can be fitted with pressure control up to 1 bar, making it the ideal tool for downscaling applications in the food, pharmaceutical and research industries. A steel vessel with a total volume of up to 5 litres is also available.

All Bioengineering benchtop fermenters are supplied with the advanced Bio­SCADA Plant cell reactor software – license-free and with extensive functionality.
