Durable borosilicate glass funnels with a 58° cone angle for efficient filtration.
Chemical-resistant funnel with angled stem and air-release grooves.
Medium chemical-resistant funnel with air-release grooves and angled stem.
58° Angle Borosilicate Glass Filtration Funnels
These laboratory filtration funnels are made of high-quality borosilicate glass with a precise 58° cone angle. The narrower angle enhances filtration efficiency by preventing filter paper from sealing against the glass, allowing better flow. Designed for chemical resistance and durability, these funnels feature heavy-wall construction with reinforced, fire-polished edges for long-term laboratory use.

Funnel, Long Stem (Large) 150 mm, Polypropylene
This translucent plastic funnel allows for convenient pouring of liquids into containers. It is a useful tool for safe pouring in the laboratory.
Made of Polypropylene, it is resistant to all inorganic acids, bases and salt solutions. It is also safe to be used with many organic chemicals including alcohols.
"Polypropylene chemical resistance" is well studied and compatibility charts can be found online.
Design includes thin lines embossed on the outer body of the funnel allowing the air to exit from your container while the liquid is entering. This results in a continuous and smooth flow of liquid. The lower part of the stem is cut on a 45 degree angle to direct the flow of liquid to one point and avoid random drips.
Product Specifications
| Mouth/ Rim Diameter | 150 mm (6 inches) |
| Stem Length | 110 mm (more than 4 inches) |
| Overall Height | More than 230 mm (more than 9 inches) |
