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.

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?

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