Sartorius Stedim Biotech adds PESU membranes to benchtop filtration techs

Sartorius Stedim Biotech (SSB) claims benchtop vaccine and protein purification techs could save developers €2000 per batch and reduce processing time by 60%.

The new filtration assemblies – which is part of SSB’s Sartocon range – are based on the firm’s polyethersulfone membrane (PESU), which filter proteins and vaccines based on their molecular weight across a broad pH and temperature range.

Previously the Sartocon systems used SSB’s Hydrosart membranes according to spokesman Frank Meyeroltmanns, who said: “Now customers can select from a broader range of membrane polymers and cut offs for ensuring optimal parameter for their specific process.”

He added that: “When compared with reusable filter cassettes, we estimate that using these new single-use, PESU membrane-based assemblies will reduce processing time by around 60 percent and could save up to €2,000 per batch on buffer and water costs.”

The single-use system filtration assemblies are also so called "closed loop" systems, which means they are fully enclosed and can be used in current Good Manufacturing Practices (cGMP) environments for a broad range of applications.

This flexibility makes the system ideal for contract manufacturing organisations (CMO) and other organizations operating multi-product production facilities according to SSB.

The launch follows just a month after SSB bundled its upstream technologies into a single offering – called Connect Upstream.

At the time the firm said the move was already designed to help developers get products to market quicker and more cheaply.
