Features printed funnels that identify membrane type and product number for easy product product identification. Corning™ Disposable Vacuum Filter/Storage Systems provide a complete solution for your filtering needs.

When conducting analytical filtration in your lab, we understand that particle retention efficiency is critical to your research. Producing accurate results in this type of testing is especially dependent on the filter's performance in retaining microbes on the membrane.

The Witt filtration apparatus is used for solid-liquid filtration in which the filtrate is subsequently further processed.
