In vacuum-assisted filtration, filter funnels are required for microbiological testing of germs or fungi, for example. Filter funnels are made of materials such as glass, metal or plastic and are used in various filtration processes. There are single-use laboratory funnels and reusable filter funnels, e.g. made of glass, which are suitable for applications involving the use of chemicals.
We supply sterile and non-sterile filter funnels in various sizes made of polypropylene, polystyrene, stainless steel and glass. You can also obtain filter funnel holders, manifolds and filtration apparatuses at Analytics-Shop.
