Rugged magnetic drive on permanent magnets (NO MECHANICAL PARTS in the drive such as Motor / belt, Unwanted bearings etc.. & hence NO WEAR AND TEAR, assuring years of continuous and trouble free operation). – Facility of variable throw diameters on the same machine. The user can vary the diameter of orbital rotation from 12.5 mm / 25 mm / 50 mm or even 70 mm for high or low aeration/oxygen transfer rate. Extremely useful option for mammalian cell cultivation where we cannot have a high speed (owing to shear forces) but we can still have a large diameter of orbital rotation. – Upgrade possibility anytime in the future with most reliable CO2 Control and very unique Humidity Control without any spraying / fumigation (ensures very accurate High Humidity) without the need of even a continuous water supply. In case of machines with humidity control, a Heated Front Glass Door is provided as standard feature to prevent condensation & for a clear view of the cultures.
