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.

Product Specifications

Applications and Benefits:

• Efficient laboratory filtration with improved flow rate
• Compatible with standard filter papers
• Durable, resistant to chemical corrosion and thermal shock
• Heavy-wall glass for mechanical strength and longevity
• Fire-polished edges for safety and smooth liquid transfer
• Ideal for chemistry, environmental, and biological labs

Caution:

Avoid using with hot concentrated phosphoric acid, hydrofluoric acid, or strong alkalis for prolonged exposure. Sudden extreme temperature changes should also be avoided to prevent breakage.
