1. Medium cooling without cooling water

LAMBDA Peltier electronic cooling loop for MINIFOR fermenter-bioreactor Cooling with this device is based on the electronic cooling effect produced by the flow of electric current through a Peltier cell. The Peltier cell  allows cooling of the medium without the necessity of other means such as a refrigerating compressor or cooling water baths…

2. Automatic recognition of the culture volume

A very compact control system, which will allow good measurement and control of all important parameters by the same unit, is preferable for the user. Living organisms are extremely complex and it is desirable to measure and control as many parameters as possible. This will help to identify problems when they possibly arise. Therefore, we decided…

3. Revolutionary radiation heating

The vessel is heated from underneath by infrared radiation generated by a spiral heater of high heating power but very low heat capacity. Heat rays are concentrated by the gilded parabolic reflector with 98 % efficiency onto the bottom of the vessel, where about 50% is absorbed by the glass and about 50% is absorbed directly by medium. The result…
