Glass Filtration Set, Complete Vacuum Filtration Kit with Funnel, Flask & Clamp Kit, Borosilicate Glass (BORO 3.3)

Description

A complete glass vacuum filtration set provides a reliable and efficient system for separating solids from liquids in analytical, microbiological, and chemical workflows. This BORO 3.3 filtration kit includes a heavy quality funnel, vacuum filtration flask, and a secure clamp assembly designed for stable, leak free operation under reduced pressure. The clear glass components allow continuous visibility of the filtration process, supporting accurate monitoring of flow rates, sample clarity, and particulate separation during laboratory procedures.

The BORO 3.3 borosilicate composition follows ISO 3585 requirements for laboratory grade borosilicate glass and aligns with ASTM E438 guidelines for chemically resistant, heat tolerant glassware. These standards support excellent resistance to acids, solvents, and thermal variation, ensuring consistent performance throughout repeated filtration cycles. The precision ground joints and smooth internal surfaces help maintain airtight connections and prevent sample contamination, while the robust flask design supports safe vacuum operation across a wide range of laboratory applications.

This filtration set is used in microbiology sample preparation, environmental testing, water and wastewater analysis, organic chemistry, quality control labs, and educational science programs. Its dependable construction and professional level clarity meet the expectations of LabChoice Australia customers who require accurate and durable filtration equipment for routine and advanced laboratory work. Designed for repeated use in modern Australian research and teaching environments, this BORO 3.3 vacuum filtration kit offers stable operation, long service life, and consistent high quality results across filtration workflows.
