Vacuum filter cups are commonly used in the industry to degas solutions. For some liquid chromatography systems, applying a vacuum while filtering the mobile phase may remove enough gas to prevent issues.

Description générale
Les dispositifs de filtration stérilisante Stericup® et Steritop® utilisent des membranes fiables et hautement performantes pour une filtration stérilisante optimale des réactifs, tampons et milieux de laboratoire. Ces dispositifs associent des débits et des volumes filtrés supérieurs à une faible liaison non spécifique et à une conception stable et évitant tout basculement.
Cette unité de filtration à membrane en polyéthersulfone (PES) Steritop® de 250 ml et de 0,22 µm de dimension de pores peut être utilisée sur des flacons avec des ouvertures de 45 mm, conçus pour des applications sous vide.
Application
- Milieux de culture cellulaire +/- additifs
- Tampons
- Solutions biologiques

What is the maximum processing volume for Stericup® and Steritop® filters? Can I add more volume after initial filtration?
1 answer-
All Stericup® and Steritop® filters were developed for single-use application. The maximum volume is dependent on the receiver bottle capacity. Stericup® filters come with a receiver bottle with a specified maximum volume. For Steritop® filters, the maximum recommended volume is 2 L with an appropriate-sized receiver bottle. Larger processing volumes can result in membrane fouling, increase chance of spillage and contamination, and lead to possible airlock*.
*Note that devices with PES membranes can airlock if filtered to dryness. Some liquid must be left on top of the filter, then the system stopped, receiver changed or emptied, and more sample volume added before restart. This increases the chance of spillage.Helpful?
