Hirsch Filtration Funnels

Hirsch filtration funnels are essential tools for efficient small-scale filtration in laboratories. Designed for precision, these funnels are ideal for separating fine particulates from liquids, ensuring clear filtrates.

Featuring a robust porcelain or glass construction, Hirsch funnels provide durability and chemical resistance, making them suitable for various laboratory settings. Their unique design includes a perforated plate that supports filter paper, which aids in achieving more efficient filtration compared to standard funnels. The angled sides of Hirsch funnels also help in minimizing the loss of material during transfer.

These features of Hirsch funnels contribute to faster and more reliable filtration processes, saving valuable time and ensuring consistency in results. Available in multiple sizes and capacities, users can select the perfect fit for their specific filtration needs. Hirsch funnels can be used interchangeably with Buchner funnels, offering flexibility and compatibility with a wide range of filtration setups.

Whether working with Hirsch funnel filtration or combining with Buchner and Hirsch funnel systems, these funnels are indispensable for precise and effective laboratory filtration. Accessories such as rubber adapters and vacuum filtration setups further enhance their functionality, making Hirsch funnels a versatile choice for any lab.
