SSB’s new small-scale and single-use filter device Sartocon Slice 50

Sartorius Stedim Biotech (SSB), an international supplier to the biopharmaceutical industry, has added the single-use ultrafilter Sartocon Slice 50 to its portfolio.

The new crossflow filter device is particularly for membrane screening and small-volume process development.

Sartocon Slice 50 is offered as an encapsulated and ready-to-use crossflow module with a filter area of 50cm2 and a variety of molecular weight cutoffs. The cGMP validated self-contained unit does not require a compression holder and is available in a choice of two polymers.

The Hydrosart membrane is a stable polymer suitable for a broad pH range and can be depyrogenated using NaOH at elevated temperatures. It is hydrophilic, making it non-protein-binding and virtually non-fouling, and delivers a high flux.

The polyethersulfone membrane (PESU), which is well established in the biotechnological and pharmaceutical industries, is a stable polymer suitable for a broad pH and temperature range.

A major benefit of the new crossflow filter device is its linear scalability, along with identical materials of construction. This eases transfer of process development results to the next scale up level.

Sartocon Slice 50 can easily be interfaced with SSB’s recently launched Sartoflow Smart benchtop crossflow system, as well as with many other laboratory-scale filtration systems.
