Description

Filter Funnels Long Stem 60 Degree Cone, BORO 3.3 Glass are designed for clean, controlled gravity filtration and safe liquid transfer where chemical resistance, thermal stability, and consistent flow are essential. The 60° cone angle supports efficient filter paper seating and steady drainage, helping reduce bypass and improve filtration consistency during routine solution clarification and precipitate removal. The long stem enables deeper insertion into receiving vessels such as conical flasks and filter flasks, helping reduce splashing, improve flow direction, and minimise product loss during filtration or decanting.

Manufactured from high quality LabChoice BORO 3.3 borosilicate glass, these funnels offer excellent thermal stability, low thermal expansion, and strong chemical resistance to many common laboratory reagents and solvents. BORO 3.3 glass performance aligns with recognised borosilicate standards such as ISO 3585 and ASTM E438 Type I, supporting dependable durability under routine laboratory handling and moderate heating conditions. Smooth internal surfaces minimise residue retention and support efficient cleaning between uses, while consistent wall thickness improves robustness for frequent bench work.

The 60° cone profile helps maintain a stable filter paper fit, supporting smoother flow and more consistent filtration, particularly for routine aqueous solutions and common laboratory solvents. For best practice, select the correct funnel diameter for your filter paper size, pre-wet the filter paper where required, avoid overfilling, and support larger funnels with a ring stand to reduce tipping risk.

Supplied by LabChoice Australia, these BORO 3.3 long stem 60° filter funnels are widely used across Australian schools, universities, research facilities, medical laboratories, and industrial quality control environments where durable borosilicate filtration and transfer equipment supports consistent results.
