Laboratory separating funnels supplied by LabChoice Australia provide controlled and efficient liquid liquid separation for analytical chemistry, sample purification and solvent extraction workflows across teaching, industrial and research laboratories. Available in high clarity BORO 3.3 borosilicate glass and chemically resistant polypropylene, these funnels are engineered to deliver reliable phase separation, solvent handling accuracy and safe reagent transfer. Glass models comply with ISO 3585 and ASTM E438 Type 1 Class A standards, ensuring exceptional resistance to thermal shock, chemical attack and long term wear. Polypropylene variants follow USP Class VI and ISO 10993 biocompatibility frameworks and adhere to ASTM D4101 performance requirements for laboratory grade polymers.
Each separating funnel features a tapered body that promotes clean phase layering and efficient separation of immiscible liquids. BORO 3.3 glass versions provide superior clarity for accurate interface observation, while PP models offer lightweight, shatter resistant handling suitable for high throughput environments. High precision PTFE or glass stopcocks ensure smooth reagent release and excellent chemical resistance, supporting reliable dropwise or continuous flow control. Wide mouth designs allow easy loading, cleaning and sample transfer, while standard ground glass joints manufactured to ISO 383 and ASTM E676 ensure full interchangeability with laboratory assemblies.
Separating funnels are essential in organic synthesis, solvent extraction, impurity removal, washing procedures, partitioning workflows, environmental testing, pharmaceutical QC and general liquid phase purification. Their balanced geometry and precise flow control enable consistent and reproducible separations of aqueous and organic layers, supporting analytical accuracy in workflows involving dyes, oils, solvents, acids, bases and natural product extracts.
All separating funnels supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional accuracy checks, stopcock sealing verification, chemical resistance testing conducted under ASTM D543 principles, clarity evaluation, surface finish inspection and thermal shock testing for borosilicate glass variants. Materials are validated for compliance with ISO 3585, ASTM E438, ISO 10993 and ASTM D4101 performance standards depending on model type. These rigorous measures ensure safe, predictable and long lasting performance for laboratories requiring high precision separation glassware.
