Stericup® 过滤装置
Stericup真空抽滤系统包含一个Steritop真空抽装置和一个接收瓶,用来处理和储存150 mL至1,000 mL液体。
Stericup真空抽滤系统包含一个Steritop过滤装置和一个接收瓶,用来处理和储存150 mL至1,000 mL液体。
接收瓶设计新颖,不会倾倒,易于抓握,外形紧凑,在过滤过程中保持稳定,因此Stericup过滤装置特别适合在层流罩中使用。
另一个方便的特点是,接收瓶的底部稍微凹陷,盖上盖的瓶子可以方便地叠放储存。

问与答
问题 | 回答 |
---|---|
Are Stericup and Steritop units autoclavable? | No. The highest temperature that the product can be used at is 50C ( 122F ). |
Can I filter 100% serum with the Stericup? | Yes. The Express membrane is the highest throughput membrane available on the market today. |
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. |
Can I bubble point my Stericup/top? | No. The unit is not designed to handle the pressures required to perform a bubble point test. It is designed to be run under vacuum only (15 psi max). Bubble points for any of the membranes in the Stericups/tops need to be run at pressures ranging from 22 psi to 57psi. |
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. |
For tissue culture media filtration which membrane should I use? | The best membrane for this application is the Millipore Express membrane. It was designed specifically to filter tissue culture media with serum. It is low protein binding, has fast flow and high throughput (which is also called filter capacity). |
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. |
Is the Express membrane surfactant free? | Yes, the Express membrane is surfactant free. It also has a very low extractables specification - less then 1.5% by weight. |
