The Thermo Scientific™ HyPerforma™ DynaDrive™ Single-Use Bioreactor (S.U.B.) is our latest advancement in S.U.B. technology; it offers better performance and is scalable to larger volumes than previous bioreactors. The complete HyPerforma DynaDrive S.U.B. system consists of a 500 L bioreactor tank and a Thermo Scientific™ HyPerforma™ DynaDrive™ BioProcess Container (BPC). This cube-shaped tank and unique stirred-tank design utilizes a novel drive train with multiple impellers. The mixing capability of the bioreactor is superior, which enables optimal mixing and mass transfer performance. The newly designed tank shape allows for mixing at very low volumes and has a turndown ratio of 20:1.
