Hach carries high quality filters, funnels, and pumps from Millipore, Pall, and Microfil in a variety of sizes and shapes. Disposable funnels can save sterilisation and mess; stainless-steal manifolds offer long-term, autoclavable solutions. Clear, shatter-resistant polypropylene separatory funnels allow for safe and easy separation processes - available in Squibb and other shapes, along with separatory funnel supports. Vacuum pumps, both hand-operated and electrical, create vacuum for the micro testing process.
