Description

The RTS-8 is an eight position bioreactor that utilises patented Reverse-Spin® technology to non-invasively optimise mixing and oxygenation for aerobic cell cultivation. With this novel technology a cell suspension in a single use 50 mL Falcon tube with a membrane filter is rotated around its axis in alternating directions to achieve a mass transfer coefficient (k_La (h^-1)) of up to 450. This level of mass transfer is ideal for efficient aerobic cell culture.

The RTS-8 features a laser-based optical system that emits NIR light at 850 nm. Highly accurate measurements of OD can be taken from 1 - 60 times per hour to provide a profile of cell growth in real-time. The temperature control range for the RTS-8 is 15°C below ambient to +60°C.

Key applications for the RTS-8 include:

• Fermentation real time growth kinetics
• Clone candidate screening
• Protein expression
• Temperature stress and fluctuation experiments
• Media screening and optimisation
• Growth characterisation
• Inhibition and toxicity tests
• Strain quality control
• Initial bioprocess optimisation studies
