The Funnel, DIN/ISO & USP manufactured by Edulabs is an indispensable piece of general laboratory glassware engineered for fluid transfer and liquid clarification procedures. Designed to meet strict international standards, including DIN/ISO and United States Pharmacopeia (USP) guidelines, this funnel ensures zero chemical leaching, high dimensional accuracy, and exceptional performance across clinical, analytical, and educational environments.

The physical design of the Edulabs laboratory funnel features a precision-formed 60-degree internal angle bowl. This specific geometry is mathematically optimized to support standard circular filter paper folded into a cone, creating a snug fit against the inner glass walls. This snug alignment facilitates rapid fluid flow via gravity filtration while preventing air pockets that can slow down filtration speeds. The uniform glass wall thickness ensures mechanical strength and resistance to thermal stress during liquid transfers involving hot solutions.

Constructed entirely from premium BORO 3.3 Borosilicate Glass, this funnel offers near-universal chemical durability. It remains unaffected by exposure to concentrated acids, organic solvents, halogenated liquids, and alkaline solutions, making it a reliable tool for wet chemistry, reagent preparation, and sample transfer. The narrow delivery stem is fire-polished at both ends to reduce liquid hold-up and minimize splash formation when discharging fluids into narrow-necked volumetric flasks or bottles.

Available in an extensive range of bowl diameter sizes from 25 mm up to 150 mm, the Edulabs Glass Funnel caters to both micro-scale transfers and high-volume liquid filtration. By adhering to international USP and ISO manufacturing standards, Edulabs provides laboratories with dependable, durable, and chemically pure transferring solutions for daily operational excellence.
