Short-stem borosilicate glass 3.3 funnel ASTM E1905
Short-stem funnel in borosilicate 3.3 glass, type 1 class A. Fire-polished stem, thick walls and moulded edges. Conforms to ASTM E1905.
Specifications
- Material: Borosilicate 3.3, type 1 class A
- Standard: ASTM E1905
- Stem: Fire-polished
- Walls: Thick and uniform; moulded edges
- Stem length: Short
Applications
Reagent transfers, gravity filtration with filter paper and analytical assemblies. The short stem suits wide-mouth vessels and reduces splashing on pouring.
Used in chemistry laboratories, quality control, teaching environments and settings involving solvents or dilute acids.
Why borosilicate 3.3
Borosilicate 3.3 is the reference glass for technical labware. Resistant to most acids, dilute bases and organic solvents—it handles sudden thermal changes and routine daily use better than soda-lime glass. Suitable for contact with aggressive reagents or temperature baths.
Construction
- Edges: Moulded to prevent chipping
- Stem: Fire-polished for clean flow and precise fit
- Walls: Uniform wall thickness throughout
