일반 설명

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 ® 250 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.

애플리케이션

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

질문

1–10 / 15 질문  

  1. Can Stericup® and Steritop® filters be reused?

    1 답변

    1. All Stericup® and Steritop® filters were developed for single use, disposable processing.

      도움이 되었습니까?

  2. What is the difference between classic Stericup® filters and Stericup® “Quick Release” filters?

    1 답변

    1. Stericup® Quick Release, or “QR”, filters feature a connection between funnel filter and receiver bottle that requires only a quarter-turn release to facilitate funnel removal. These filters come fully engaged – there is no need to tighten before use. The receiver bottle cap has flanges on the top surface to improve grip, as well as a positive lock stop to ensure a leak-proof seal with the receiver bottle. Other improvements include a large, frosted writing surface on the receiver bottle and a lighter cap color to facilitate labelling, more prominent volume markings on the filtration funnel and receiver bottle, and a product label with a peel-off lot record strip on the bag for easy viewing in storage.

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

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

    1 답변

    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

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

    1 답변

    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)

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

    1 답변

    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.
