Buchner funnels made from polypropylene and supplied by LabChoice Australia provide durable, chemically resistant and lightweight filtration solutions for teaching, analytical and industrial laboratory environments. Manufactured from high quality laboratory grade PP that aligns with ASTM D4101 specifications and evaluated against ISO 10993 biocompatibility frameworks, these funnels offer excellent resistance to acids, alkalis and a wide range of solvents. Their rigid, non reactive construction ensures reliable performance during vacuum or gravity filtration while avoiding contamination risks associated with glass or ceramic components.
Each polypropylene Buchner funnel features a perforated plate designed to support filter papers securely during filtration of fine particulates, precipitates, microbial cultures and suspended solids. The smooth internal surfaces promote consistent flow and easy cleaning, while the robust PP body offers impact resistance ideal for high throughput laboratories, field use and teaching environments. The material’s low extractables profile helps preserve sample integrity when filtering sensitive solutions, buffers or biological media.
Polypropylene Buchner funnels are widely used in microbiology labs, water testing facilities, environmental analysis, educational laboratories, food and beverage QC workflows and general chemical filtration tasks. Their lightweight design allows safe handling during wet filtration, and their compatibility with vacuum filtration setups supports faster throughput compared with gravity filtration alone. PP funnels are also suitable for applications requiring resistance to thermal variation, routine sterilisation and repeated chemical exposure.
All polypropylene Buchner funnels supplied by LabChoice Australia undergo ISO 9001 aligned quality control procedures. This includes dimensional accuracy checks, perforated plate integrity testing, material verification, chemical resistance evaluation under ASTM D543 guidelines and visual inspection to ensure smooth surfaces free from manufacturing defects. Funnels are validated for compliance with ASTM D4101 polymer specifications and assessed against ISO 10993 requirements for laboratory polymer suitability. These rigorous processes ensure dependable, safe and long lasting performance for laboratories requiring robust and cost effective filtration equipment.
