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.

General description
Die sterilen Stericup® und Steritop® Filtrationseinheiten verwenden zuverlässige Hochleistungsmembranen für eine optimale Sterilfiltration von Laborreagenzien, Puffern und Medien. Diese Geräte kombinieren überlegene Durchflussraten und Durchsatz mit geringer unspezifischer Bindung und einem stabilen Design ohne Spitzen.
Diese Stericup® Polyethersulfon(PES)-Membranfiltereinheit mit einer Porengröße von 0,22 μm kombiniert einen 150-ml-Flaschenverschluss mit einem 150-ml-Auffangkolben und Deckel für Verarbeitung und Lagerung.
Application
- Gewebekulturmedien +/- Additive
- Puffer
- Biologische Lösungen
Features and Benefits
- Der Schnellverschluss-Filtertrichter wird mit nur einer Vierteldrehung von der Sammelflasche getrennt,— was die Wahrscheinlichkeit eines Verschüttens verringert und die Handhabung auf dem Labortisch oder unter der Haube erleichtert.
- Die fett gedruckte Produktkennzeichnung auf dem Steritop® Filtertrichter zeigt deutlich die Membraneigenschaften einschließlich Zusammensetzung und Porengröße an, um eine schnelle, anwendungsgerechte Produktauswahl zu ermöglichen.
- Die Click-Dichtungskappe ist angeflanscht und modifiziert, um einen festen Halt unter nassen oder trockenen Bedingungen zu ermöglichen—und ein taktiler Anschlag bestätigt den sicheren Verschluss. Sorgen Sie sich weniger über die Möglichkeit eines Verschüttens oder einer Kontamination des sterilisierten Inhalts.
- Die matte, große Beschriftungsfläche auf der Auffangflasche und die hellere Deckelfarbe erleichtern die Lesbarkeit und reduzieren unleserliche Abstriche.
- Die Verschlusskappe liegt auf der Seite auf, um das Risiko einer Kontamination zu vermeiden.
- Die Auffangbehälter sind stapelbar, um Platz zu sparen.

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

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?

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