Sterile Large-volume Filtration Samples
Larger volumes (> 5 liters) may require a capsule filter with pleated membrane. A capsule filter incorporates a larger surface by using a pleated membrane design. This larger membrane surface area allows for both faster filtration and higher volumes to be filtered. Capsule filters are ideal for positive pressure filtration and can operate at higher pressures. The volume recommendations presented below are intended as a general guide to selecting the most appropriate device.
* Total throughput (capacity) of a filter depends on the characteristics of the fluid being filtered, such as the extent of microbial contamination, viscosity, and particulate load.
