Stericup® Filter Units

The Stericup vacuum filtration system combines a Steritop vacuum filtration unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL.

The Stericup vacuum filtration system combines a Steritop filter unit with a receiver flask for processing and storing volumes from 150 mL to 1,000 mL.

Its new no tip/easy grip flask design and compact profile improve stability during filtration, make gripping the receiver easier, and make Stericup Filter Units ideal for use in laminar flow hoods.

As an added convenience, the bottom of the receiver flask is slightly recessed, enabling capped flasks to be stacked for convenient storage.

* These products have been tested for use in stem cell research applications. To determine their effects on Mouse Stem Cell growth or differentiation, three lots of Stericup-GP devices were used to filter media with LIF. Once filtered, this media was used to passage mouse stem cells five times to verify that Stericup-GP filtration does not impact pluripotency of mouse stem cells.

FAQ

QuestionAnswer
Can I purchase extra receiver flasks for the Stericups separately?Yes, the catalog number is SC00B10RE.
Can you freeze Stericup units?You can successfully freeze and store many aqueous solutions ( such as culture media ) at temperatures to -20C ( -4F ). We strongly recommend that you run a trial under actual conditions to test for suitability of the bottles for frozen storage.
Do you have a filter for 100% serum?Yes, you can filter serum with Millipore Express membrane. The Express membrane was designed for this application and offers fast filtration time. Millipore Express is available in a large number of filter devices including Millex syringe filters, Stericup and Steritop vacuum devices, Sterivac for large volumes of media and Steriflip for 50 mls.
I want to sterilize 100% ethanol. Are any of the Stericups or Steritops compatible with ethanol?The funnel and receiver flask is made of polystyrene. Any molded polystyrene will craze in pure ethanol and could structurally fail depending on the forces being applied to it. The funnel could handle the short exposure time but the receiver would craze eventually. Therefore we would not recommend the Stericup with 100% ethanol. The Steritop, if you keep the exposure time to the funnel minimal, should be fine. As you dilute the alcohol the compatibility improves.

Both Express and Durapore membranes are compatible. MCE is not.
I will be filtering tissue culture media with your Stericup/top and am concerned that wetting agents in the filter could effect my cells. Which membrane type would you recommend to avoid this?All of Millipore's Tissue Culture Media filtration sterilization devices contain membranes that are wetting agent (surfactant ) free.
When I use my Stericup/top, sometimes some of my sterilized solution gets pulled into my vacuum line. How can I eliminate this from happening?Attach your vacuum tubing and turn the vacuum on before adding the liquid to the Stericup/top. This eliminates any initial solution that flowed through the membrane before starting the vacuum from being pulled into the vacuum line.
What is the diameter of the membrane in the Stericup and Steritop units?All of the cups and tops currently have a 70mm diameter membrane, which has 43 cm2 of surface area.
Should I filter my acrylamide solution prior to gel casting?Yes, filtering your acrylamide solution before adding the polymerization activator ammonium persulfate and TEMED will accomplish two things.
1. It will eliminate particulate matter that may interfere with base calling when sequencing or that may create "hot" spots in the gel, and
2. It will aid in degassing, which will promote efficient polymerization of the gel.

Products appropriate for this application would be Stericup, Steritop or Steriflip with express membrane.
It sounds like air is leaking into my Stericup, what should I do?First make sure that the top is securely fastened to the base. Discontinue use if there appears to be any cracks on the apparatus.
What Stericup would you recommend to remove mycoplasma?The Stericup VP ontains an 0.1um Express membrane. The VP membrane has been validated for the removal of mycoplasma.
