Sterilizing Filtration of Aqueous Solutions
How ready-to-connect units from Sartorius
fulfill the requirements of the customers.
Scale-up
The combination of the large filter area and
the optimized geometry of the filter supports
of Minisarts and Sartolab P20 units ensure
high flow rates at low pressures and optimal
throughputs. Often, the filterable volume
can even be doubled by using Minisart-plus
or Sartolab P20 plus units with an integrated
prefilter. Sartobran 150 and 300 and
Sartobran P Capsules contain a pleated
double membrane for maximum economy.
Regulatory compliance
All units are comprised of practice-proven
cellulose acetate or polyethersulfone
membrane filters, tested according to HIMA.
Each single unit is tested for housing and
membrane integrity prior to packaging, and
statistically valid numbers of units from each
batch are subjected to the Bacteria Challenge
Test. All types can be integrity tested by the
user before and after filtration.
All materials pass the USP Plastics Test
Class VI. Sartorius cellulose acetate and
PES membrane filters have proven to display
particularly low adsorption and assure
minimal loss of proteins and preservatives
(see diagram).
