Durable borosilicate glass funnels with a 58° cone angle for efficient filtration.
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.
