Kbiotech Bio-Book Compact is a new line of latest generation Bioreactors that allow for the growth and cultivation of cells, microorganisms, and other biological systems in controlled conditions. They are designed to be small and portable, making them ideal for laboratory research, development but also for advanced bioprocessing and small-scale GMP production.

Compact bioreactors vessel are available in a variety of sizes and capacities. The smallest models can hold a few as 50 milliliters of culture medium, while the largest models can hold up to 20 or 30 litres, You can interchange different types of autoclavable Glass and Stainless Steel vessels but also Disposable vessels (click here for more informations). Compact bioreactors are typically equipped with a mechanical agitation system or magnetic stirring system on request with a choice of rushton, pitched, marine blade impellers for up or down flow as well as customizable impellers. The Compact control system is equipped with an accurate liquid dosing system for nutrients and additives with variable speed stepper pumps and gas mixing with Massflow meters or Rotameters with selectable flow rate based on your application. The Compact control unit is equipped with standard measurements and controls such as Temperature, PH, dissolved oxygen, foam & level but also already provides additional channels for the interface of auxiliary sensors such as for the measurement of Biomass Turbidity, Capacitance, O2/CO2/CH4/Methane gas analyzers, dissolved CO2 and other online devices such as Glucose.
