Glassco Borosilicate Laboratory Funnel, DIN/ISO and USP
The Glassco laboratory funnel is manufactured from borosilicate 3.3 glass in compliance with DIN/ISO and USP standards — providing a reliable, chemically resistant, and dimensionally consistent general-purpose laboratory funnel for routine filtration, liquid transfer, and reagent addition workflows. Available in rim diameters from 35mm to 150mm with matched stem lengths and outer diameters, these funnels cover the full range of common laboratory filtration and liquid handling requirements.
Borosilicate 3.3 glass provides excellent resistance to the acids, bases, and organic solvents encountered in routine laboratory use, along with good thermal stability for applications involving heated solutions. All funnels feature white printing for clear identification and are supplied from Glassco’s European warehouse in the Netherlands for fast delivery across Ireland.
Key Features
Borosilicate 3.3 Glass — DIN/ISO and USP Compliant
Manufactured from borosilicate 3.3 glass in compliance with DIN/ISO and USP standards, providing the chemical resistance, dimensional consistency, and material quality required for use in pharmaceutical, analytical, and regulated research laboratory environments.
Full Range of Rim Diameters
Available in rim diameters from 35mm to 150mm — covering the full range of standard filter paper sizes and laboratory funnel applications. The appropriate rim diameter depends on the filter paper size being used and the volume of material being filtered per batch.
Matched Stem Configurations
Each rim diameter size is supplied with a matched stem length and outer diameter, ensuring appropriate flow rate and compatibility with standard laboratory filter setups, ring stands, and funnel racks across the full size range.
Smooth Conical Bowl
The smooth conical bowl interior minimises filter paper tearing and ensures consistent flow of filtrate through the filter medium — important for maintaining filtration efficiency and reproducibility across routine laboratory filtration workflows.
White Printing
Durable white printing on the glass surface for clear size identification during laboratory use.
EU Warehouse — Fast Delivery to Ireland
Supplied from Glassco’s European distribution warehouse in the Netherlands, providing fast and reliable delivery across Ireland with shorter lead times than direct import from outside the EU.

Applications
- Filtration with filter paper — gravity filtration of solutions and suspensions using standard circular filter papers in analytical and preparative chemistry workflows
- Liquid transfer — controlled transfer of liquids between vessels with narrow necks, minimising spillage during reagent preparation and sample handling
- Reagent addition — addition of liquids to reaction vessels, columns, and other laboratory apparatus during synthesis and preparation procedures
- Pharmaceutical QC — general filtration and liquid handling in regulated pharmaceutical quality control environments
- Sample preparation — gravity filtration of sample extracts and reagent solutions prior to analytical measurement
