Microsart® funnels are sterile plastic funnels. They enable fast execution of filtration steps required in routine testing of water, food and beverages, as well as pharmaceutical and cosmetic products. The mesh membrane is mounted on a stainless steel filter holder, and the Microsart® funnel is easy and practical to install. The funnel is made of polypropylene and is therefore elastic enough for optimal sealing. Placed volume labels inside the hoppers ensure accurate dosing. The large inner diameter ensures a high flow rate, and the optimized shape allows a thorough rinsing of the system after filtration.
