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.

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.

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?
