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 Stericup® E is a 38mm thread collar which uses a 0.22 μm pore size polyethersulfone (PES) membrane filter unit combined with a 1000 mL receiver flask and cap for processing and storage. The 38 mm thread directly connects to our media bottles and majority of other standard commercial media bottles.
Use only glass or plastic bottles designed for vacuum applications.

Application
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
For Research Use Only
Features and Benefits
- The filter collar disconnects from the receiver bottle with just a quarter turn—reducing the likelihood of spillage and making it easier to manipulate on the bench or under the hood.
- Bold product identification on the filter collar plainly displays membrane characteristics, including composition and pore size, for rapid, application-appropriate product selection.
- Click seal cap is flanged and modified to enable a firm grip in wet or dry conditions—and a tactile stop confirms secure closure. Worry less about the possibility of spilling or contamination of sterilized contents.
- Frosted, ample writing surface on the receiver bottle and lighter cap color facilitate clear labelling to improve legibility and reduce unreadable smears.
- Click seal cap rests on the side to avoid risk of contamination.
- Receiver bottles are stackable to save storage space.

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.

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