Guidance for Industry Sterile Drug Products Produced by Aseptic Processing — Current Good Manufacturing Practice U.S. Department of Health and Human Services In most cases, we sterile filter the finished mixed product ahead of filling. We have established procedures for sterile filtering through several different types and sizes of filters. If the filter needed for sterile filtration of your product is not part of our standard range, we can evaluate and implement a new filter type and size ahead of your manufacture. Sterile air filters reduce batch contamination, spoilage and product loss, effective sterile air filtration is a necessary part of your process.

Filter-sterilize volumes up to 1,000 mL or 2,000 mL, using Sterivex™ pressure-driven filter units (capacity depends on the type of membrane used in the device). Here, we illustrate the basic steps involved with sterile-filtering reagents with a vacuum filter. This technique is useful for preventing the contamination Used for heat sensitive media Removal of multiple particle sizes Allows for fairly high throughput Disadvantages: Each filter has a specific nominal pore size Unable to separate microorganisms that have the same size May require a high differential pressure This film shows the process of sterile filtration used for liquid media which are not autoclavable due to their sensitivity to heat.German version is also av 2019-02-05 2009-03-13 Sterile filtration of your final drug is the critical step to ensure product sterility and safety.
