Disposable Filters
Disposable Filter is a filter that cannot be cleaned and re-used. It must be discarded and replaced at time of change-out. These filters are an easy, effective way to meet the filtration requirements of the U.S. Environmental Protection Agency, as they incorporate a 0.45 μm membrane into a disposable device.
Features of disposable filters
Centrifuges can be expensive to purchase, involve high maintenance and a great deal of personnel involvement to operate under aseptic or "clean" conditions. Batch filtration equipment can also be expensive and involves a high degree of operator attendance. Both types of units used in the small production environment may be so radically different than that available for commercial production, that scaleup is costly. In addition, centrifugation and batch filtration present costly manual cleaning operations that require the unit to be opened to the environment. This, in turn, leads to chances of exposure of the material being processed to the outside "uncontrolled" environment, increasing the risks to the final product as well as to operations personnel. Because of this, there is a need for another type of equipment to conduct these solid-liquid separations that addresses some of the short-comings mentioned above.
Advantages of disposable filters
- Compact size with no bulky holder requiring replacement filter discs
- Almost five times the effective filtration area obtained with 142 mm disc filters
- Reduces the need for multiple filter changes
- Assures rapid sample filtration
- Fast change-out for increased efficiency
- No hazardous residue on the fitler housing
- No handling of the filter element for enhanced safety
- Self-contained, low maintenance and disposal
- No costly decontamination
- No assembly/disassembly, nor the multiple filter changes associated with reusable filter holders
