Product Description

Our 60° angle filtering funnels are essential for precise and reliable separation of solids from liquids in laboratory settings. Manufactured from chemical-resistant glass, these funnels conform to IS 1591 and ISO/DIN 4798 standards, ensuring accuracy and compatibility with global laboratory requirements.

Each funnel features a smooth exterior, a robust body for secure handling, and a perfectly engineered 60-degree cone for optimal filtration performance. Bottom stems are cut to match expected filter paper sizes and maintain smooth, rapid flow without clogging. Available in a wide variety of sizes, these funnels support routine filtration work all the way up to bulk/industrial scale.
