General description

Work with ease and filter with confidence with Stericup® and Steritop® Filtration Systems.

Stericup ® and Steritop ® sterile filtration devices use reliable, high-performance membranes for optimum sterile filtration of laboratory reagents, buffers, and media. These devices combine superior flow rates and throughput with low non-specific binding and a stable, no-tip design.

This Steritop ® 150 mL bottle top 0.22 μm pore size polyethersulfone (PES) membrane filter unit can be used on bottles with 33 mm openings, designed for vacuum applications.

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

  1. Can we filter oil-type liquids with Stericup® filters?

    Can we filter oil-type liquids with Stericup® filters?

    1 answer

    1. Likely not, due to pore size/possible fouling/chemical compatibility. Refer to our guide, "Chemical compatibility of filter components": https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/302/855/membrane-chemical-compatibility-ds2532en-ms.pdf

  6. The User Guide says “Use only glass or plastic bottles designed for vacuum applications”. Can you specify which bottles are compatible?

    1 answer

    1. Steritop® Quick Release bottle top units require a vacuum-rated receiver bottle with either a GL33 or GL45 mm closure thread as specified. Steritop® E bottle top units require a vacuum-rated receiver bottle with a GL45 mm closure thread. Bottles no larger than 2 L should be used.
      Glass bottles, GL33:
      • Wheaton media bottles (glass), 500 mL (Product Z364886)
      • Wheaton media bottles (glass), 1 L (Product Z364894)

  8. What is the maximum processing volume for Stericup® and Steritop® filters? Can I add more volume after initial filtration?

    1 answer

    1. 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.
