Sartolab RF/BT are disposable vacuum filtration units. The Bottle Top (BT) units contain an optimized Sartorius PES membrane and combine highest flow-rates and throughput with extremely low protein binding and extractables. They are therefore the product of choice for sterile filtration of tissue culture media, buffers, additives and other aqueous biologicals. Sartolab BT vacuum units are available as 150 ml, 500 ml and 1000 ml units.

  • Low protein binding
  • Fast flow and high throughput
