Laboratory Funnels

Laboratory funnels are essential glassware items used across a wide range of sample handling, filtration, and liquid transfer applications in pharmaceutical, analytical, research, and academic laboratory environments. The appropriate selection of funnel type — whether a standard glass funnel for filtration and liquid transfer, or a separating funnel for liquid-liquid extraction — is an important consideration for laboratories seeking reliable and reproducible results across their routine workflows.

Varen Scientific supplies a comprehensive range of laboratory funnels to pharmaceutical, analytical, and research laboratories across Ireland. Our laboratory funnel range includes borosilicate 3.3 glass funnels in a range of rim diameters, and separating funnels in both Squibb and conical configurations — available across a wide range of capacities with PTFE stopcocks for chemical resistance.

Standard borosilicate 3.3 glass funnels are used for filtration with filter paper, liquid transfer between vessels, and the addition of reagents to reaction vessels. Available in rim diameters from 35mm to 150mm with varying stem lengths and diameters, the appropriate funnel size depends on the volume of material being transferred and the size of the receiving vessel or filtration setup.

Separating funnels are specialist glassware items used for liquid-liquid extraction — a critical technique in analytical chemistry, pharmaceutical development, and sample preparation workflows where two immiscible liquid phases must be separated. Our separating funnels are manufactured from borosilicate 3.3 glass and feature PTFE stopcocks, which provide excellent chemical resistance and a reliable seal across a wide range of organic solvents and aggressive reagents.

Both Squibb (pear-shaped) and conical separating funnel configurations are available — each with specific advantages for different extraction applications. Our team can advise on the most appropriate funnel type and size for your specific laboratory application.
