Functional suggestions for 3 liter Perfusion-SUBs

Designed medium size PerfuseCell HSF accessory

The Heating-Support-Foot is fully interchangeable between the 2 different product ranges based on the same P-SUB-3 liter vessel size being OD137 mm. It all Plug & Play between CellMembra / Integrated and CellRetention / SUBmerged. In practice the Working Volume of both range from 400 ml to 2,500 ml though depending on chosen impeller and sensors.

Thermal control

The Heating-Support-Foot improves vastly mechanical stability for light weight 3 liter P-SUB operating in specific with partly small volumes or/and a heavy servo motor on the head plate.

The HSF design gives these benefits:

  • encapsulates 90 % of the SUB bottom circumference allowing a vessel bottom outlet such as for the CellMembra-3 Integrated P-SUB
  • as to the 35 mm HSF height allows visual inspection of the broth
  • the entire bottom area of the SUB is resting on a Titanium disc allowing thermal transfer
  • the ALU body integrate two heating rods for very fast thermal control

 

Heating-Support-Foot (HSF) beautifully bolts onto the MST. Here the MST Is driven by a Papst from Sartorius and a Teknic servo motor from the G3 PCS. Infrared camera photo show perfect temperature distribution inside the P-SUB. Same setup works equally well for CellMembra and CellRetention in the HSF.
