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

The Stericup® E and Steritop® E sterile filters are designed as a Greener Alternative for vacuum sterile filtration that significantly reduces plastic and packaging.

This Steritop® E is a 38mm thread collar which uses a 0.22 μm pore size polyethersulfone (PES) membrane filter unit. The 38 mm thread directly connects to our media bottles and majority of other standard commercial media bottles. Use a 45 mm threaded glass or plastic receiver bottle no larger than 2 liters.

Use only glass or plastic bottles 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

Features and Benefits

Bold product identification on the Steritop® E filter collar plainly displays membrane characteristics, including composition and pore size, for rapid, application-appropriate product selection.

Questions

1–10 of 15 Questions  
  1. What leachables are detected during filtration processes using Stericup® filters?

    1 answer
    1. We have not performed extractables/leachables studies for our Stericup® filters.

      Helpful?

  2. Can Stericup® bottles be placed inside freezers for long-term storage of media?

    1 answer
    1. You can successfully freeze and store many aqueous solutions (such as culture media) in Stericup® bottles at temperatures up to -20 °C (-4 °F). It is strongly recommended that you run a sample stability trial under your actual storage conditions prior to using Stericup® bottles for frozen storage.

  3. What is the maximum vacuum pressure for filtration?

    1 answer
    1. 700 mm Hg (27.5” Hg, 0.9 bar) differential vacuum at 25 °C (77 °F)

  4. Are Stericup® and Steritop® filters GMP-certified?

    1 answer
    1. No, Stericup® and Steritop® devices are not GMP-approved.

  5. What tubing can be used with Stericup® and Steritop® vacuum filters?

    What tubing can be used with Stericup® and Steritop® vacuum filters?

    1 answer
    1. Stericup® and Steritop® filters are fitted with a 1/4” tube adapter. We recommend 3/16 in. (4.8 mm) ID silicone tubing to fit this tube adapter: https://www.sigmaaldrich.com/product/mm/xx7100004

  6. 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.

  7. 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

  10. 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.
