We offer a variety of filter holders, filter flasks, adaptors, and accessories for vacuum filtration. These products are suitable for filtering botanical extracts in a broad range of volumes for further processing.
Filter holder selection is based on the desired filtration level, from rudimentary Buchner funnels to precise glass microanalysis holders. Glass filter holders provide sealed support for the filter membrane to ensure solution passes through, and not around. Depending on the system, a manifold can be added to increase throughput by running multiple solutions.
If you are building a system from scratch, Sterlitech offers complete vacuum filtration kits: these consist of a filter holder, vacuum pump, receiving flask, and other necessary parts. There are a variety of kits for different applications, available here.
