Borosilicate Powder Funnel with Ground Glass Joint

Funnel designed for transferring solids — powders, granules, crystals — fabricated from borosilicate glass with a standard ground glass joint. Seats directly onto flasks and vessels with a matching taper without adapters.

Features

• Material: Borosilicate glass
• Joint: Standard ground glass taper
• Stem: Wide bore to prevent blockages with solid materials
• Chemical resistance: Acids, bases, and common organic solvents

Applications

Charging round-bottom reaction flasks, transferring solid reagents into glass reactors, and weighing operations in organic and inorganic synthesis. Also used in quality control when introducing powdered samples into narrow-neck vessels.

The ground glass joint is particularly useful when working under inert atmosphere or when a provisional seal is required during charging.

Compatibility

Compatible with flasks, round-bottoms, and vessels fitted with a matching standard taper joint. Fits and removes in seconds — no tools, no additional rubber seals required.
