Its construction supports repeated laboratory use and sterilization procedures up to 250C without compromising integrity or performance.
Precision in Liquid Separation and MeasurementDesigned for precise extractions, the funnel is equipped with clear, acid-resistant graduation markings which provide accurate volume readings. The manual stopcock-crafted from PTFE or glass-delivers leak-proof performance, facilitating controlled separation of immiscible liquid phases with ease and minimal loss.
Versatile Design for Laboratory UseAvailable in capacities from 100 ml to 2 L, the separatory funnel features a compact, ergonomic design suitable for a variety of laboratory settings. The standard ground neck allows for a secure fit with accessories, while the autoclavable and individually packed funnel ensures both sterility and protection during transport.
FAQ's of Separatory Funnel:
Q: How does the PTFE or glass stopcock enhance the usage of the separatory funnel?
A: The manually operated PTFE or glass stopcock provides excellent chemical resistance and a leak-proof seal, allowing precise and safe control of liquid flow during the separation process.
Q: What is the process for conducting a liquid-liquid extraction using this separatory funnel?
A: Add your sample and two immiscible solvents of different densities into the funnel, secure the stopper, shake gently, and allow the mixture to settle. Open the stopcock slowly to release and collect the separated liquid phases individually.
Q: When should this separatory funnel be autoclaved?
A: The funnel should be autoclaved before initial use and after each use if sterility is necessary, as its borosilicate glass or PTFE construction tolerates high temperatures up to 250C.
Q: Where can this separatory funnel be used effectively?
A: This separatory funnel is ideal for chemical, pharmaceutical, academic, and industrial research laboratories where liquid-liquid extractions are routinely performed.
Q: What are the benefits of the acid-resistant, clearly printed graduation markings?
A: Acid-resistant graduation markings ensure durability and clear, accurate volume readings over time, enhancing the precision of extractions and the reliability of results.
Q: How does the interchangeable stopper add value to laboratory operations?
A: The ground glass or plastic stopper provides a secure closure and can be easily replaced or interchanged, allowing compatibility with various laboratory practices and extending the lifespan of the funnel.
