This question is part of the following Ask The Expert session:
It depends upon what method of ultrafiltration is best suited, however below are the typical volume ranges for our lab based upon the different types of force.
Centrifugation: 100ul to 100ml
Pressurisation: 20ml to 100ml
Tangential Flow Filtration: 100ml to 5000ml
So for example the Sartorius ambr 15 bioreactors produce working culture of 10-15ml, this would work directly with our Vivaspin Turbo 15 or Vivaspin 20 devices. Perhaps the Vivaspin Turbo 4 or Vivaspin 6 devices if some volume is lost after initial clarification.
