Sartorius expands small sample filtration to 50mL

By Samantha Black, Ph.D.

December 3, 2019 -- The new Sartolab RF 50 vacuum filtration units are available in two versions, one with an asymmetric 0.22 µm PES membrane for sterile filtration and another with a 0.45 µm PES membrane for clarification.

Sartolab RF 50, 0.22 µm, PES, vacuum filtration units are single-use units for the sterile filtration of sample volumes up to 50 mL. These products complete the Sartolab Receiver Flask (RF) | Bottle Top (BT) range.

Sartoclear Dynamics lab V50 kits for the filtration of ≤ 50 mL cell cultures comprises the Sartolab RF 50 for the filtration and either 1 or 2 pouches of filter aid for the clarification. The kits eliminate the centrifugation step and, together with the MultiStation, facilitate the filtration, avoiding extra time typically consumed for connection and stabilization.

Many customers working on small volumes of 30 – 50 mL must filter multiple samples at the same time. This creates a critical pain point in handling: Each unit must be attached to a vacuum tube, then stabilized before filtration and then disconnected again before attaching the next unit to the vacuum source. Sartorius facilitates the filtration of these smaller sample volumes through the introduction of the new Sartolab MultiStation, a stand that enables hands-free and parallel filtration of up to 6 samples.

The MultiStation, in combination with the 50 mL vacuum filtration units & the DE filter aid, is the perfect tool for customers struggling with processing many small samples of mammalian cell cultures.
