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.

Application
For Research Use Only
Stericup® and Steritop® systems are designed to reduce foaming and protein denaturation while maximizing flow and can be used for sterile vacuum filtration of aqueous solutions such as tissue culture media and biological fluids.
- Tissue culture media +/- additives
- Buffers
- Biological solutions
Features and Benefits
Bold product identification on the Steritop® filter funnel plainly displays membrane characteristics, including composition and pore size, for rapid, application-appropriate product selection.

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?
