Unsurpassed for non-vacuum, high-speed filtration, these clear funnels have internal helicoid ribs to increase the filtration speed. Vertical outer ribs prevent airlock. Made from autoclavable polymethylpentene plastic, these funnels are glass-clear, unaffected by corrosive liquids, and are heat resistant to 177°C (350°F).

These heavy-duty polypropylene (PP) analytical funnels are perfect for use in Analytical Chemistry applications. The funnels feature long, narrow stems, which make them ideal for use with liquids. The analytical funnels have internal and external ribbing which helps to prevent air lock. They are angled at exactly 60° for rapid filtration. Available in 9 different sizes, these analytical funnels accommodate standard filter paper sizes and are approved for use with food products.

Molded of polypropylene, these funnels are unbreakable and resistant to corrosion and heat. Two piece construction allows top and bottom to be separated for easy cleaning. The funnels are fully autoclavable and feature excellent chemical resistance. These funnels are approved for use with food products.

Specially designed for transferring powders, these funnels have a wide stem for clog-free filling. Made of polypropylene plastic with a 60° angle, they are steam autoclavable at 121°C (250°F).

Externally ribbed, polypropylene funnels are steam autoclavable at 121°C (250°F) and useful for a variety of lab applications.
