Separatory funnels supplied by LabChoice Australia provide controlled, contamination free liquid liquid extraction for analytical, teaching and industrial laboratory environments. Available in high clarity BORO 3.3 borosilicate glass and chemically resistant polypropylene, these funnels are engineered for phase separation, solvent extraction and purification workflows requiring precision and chemical durability. Glass models comply with ISO 3585 and ASTM E438 Type 1 Class A standards, ensuring excellent thermal stability and inertness when used with organic solvents, acids and bases. Polypropylene versions follow USP Class VI and ISO 10993 biocompatibility guidelines and align with ASTM D4101 requirements for laboratory grade polymers.
Glass separatory funnels feature uniform wall thickness, tapered bodies and precision formed stems that promote clean phase separation and controlled solvent flow. Their BORO 3.3 construction provides exceptional resistance to cracking, thermal shock and chemical attack, supporting repeated heating and cleaning cycles. PP models offer lightweight, shatter resistant handling suitable for field work, educational settings and high throughput extraction tasks. Their non reactive polymer composition is ideal for aqueous and mild organic solutions, providing safe, impact resistant performance where glass may be unsuitable.
Each funnel is fitted with a leak resistant stopcock system engineered to support smooth, controlled solvent release. PTFE stopcocks provide excellent chemical inertness and minimal torque operation, while glass stopcocks deliver robust, vacuum compatible performance for routine extraction workflows. The wide mouth design supports easy sample loading and cleaning, and the clear body allows technicians to observe interface formation and track separation progress with accuracy.
Separatory funnels are widely used in organic chemistry labs, environmental testing, pharmaceutical quality control, food and beverage analysis, petrochemical workflows and academic teaching laboratories. They support solvent extraction, impurity removal, washing procedures, liquid phase purification and partitioning of multi component mixtures. Their precise flow control and balanced geometry help maintain reproducible, contamination free separations essential for analytical reliability.
All separatory funnels supplied by LabChoice Australia undergo ISO 9001 aligned quality control inspection. This includes dimensional conformity checks, stopcock sealing verification, chemical resistance testing under ASTM D543 evaluation principles, clarity and surface finish assessment and structural stability testing. Glass models are additionally tested for thermal shock resistance to ensure compliance with ISO 3585 and ASTM E438 performance expectations. Polypropylene funnels are validated for conformity with USP Class VI, ISO 10993 and ASTM D4101 material stability standards. These rigorous measures ensure dependable, accurate and safe extraction performance for laboratories that require high quality separation equipment.
