About Borosilicate Glass separating funnel

A separatory funnel, also known as a separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture into two immiscible solvent phases of different densities.

Exceptional Chemical and Thermal Resistance

Crafted from robust borosilicate glass, this separating funnel withstands aggressive chemicals, acids, alkalis, and solvents, making it a reliable choice for various laboratory applications. The material also tolerates temperatures up to 400C, allowing safe usage across a wide range of experiments. Its PTFE stopcock complements this resistance, ensuring effective, leak-free operation even with challenging reagents.

Precision and Ease of Use for Liquid Extraction

Featuring clear graduation markings, the funnel ensures accurate volume measurement during liquid-liquid extraction. The manual PTFE stopcock enables smooth, controlled separation of phases, aiding in the reproducibility of your outcomes. Its ergonomic shape-whether pear-shaped or cylindrical-enhances pouring and handling, while the transparency provides clear visibility of phase boundaries throughout the process.

Laboratory Compliance and Versatility

Compliant with ASTM, ISO, and USP standards, this separating funnel meets strict laboratory requirements. Its autoclavable and reusable design supports sustainable, repeated use, making it cost-efficient for schools, research labs, industry, and service providers. The standard ground glass joint provides compatibility with most lab setups, and multiple available sizes cater to a variety of experiments.

FAQ's of Borosilicate Glass separating funnel:

Q: How do I use the Borosilicate Glass Separating Funnel for liquid-liquid extraction?

A: To perform a liquid-liquid extraction, add the immiscible liquids into the separating funnel, secure the glass stopper, and gently shake. After allowing layers to separate, carefully operate the PTFE stopcock to release the desired phase into a separate container. The clear gradations help with precise measurement of each phase.

Q: What benefits does the PTFE stopcock offer during separations?

A: The PTFE (Polytetrafluoroethylene) stopcock is highly chemically resistant and leak-proof, enabling precise and safe manual control over liquid flow. It ensures durable, smooth operation even when working with harsh chemicals or solvents.

Q: When should I autoclave the separating funnel, and is it safe to do so?

A: Autoclaving is recommended before and after use, especially when sterility is required. The borosilicate glass and PTFE stopcock are both autoclavable, so the funnel can safely withstand high-temperature sterilization procedures up to 400C.

Q: Where is this separating funnel most effectively used?

A: This funnel is ideal for laboratories conducting organic chemistry, pharmaceutical research, educational experiments, and any environment where separation of immiscible liquids or liquid-liquid extractions are necessary. It is widely used in research institutions, academia, and industry.

Q: What is the cleaning process for this funnel and how often should it be cleaned?

A: After use, rinse the funnel with a suitable solvent and follow with laboratory-grade detergent. Disassemble the PTFE stopcock and ground glass stopper, clean thoroughly, and allow to dry. The cleaning frequency depends on usage, but always clean immediately after use to prevent residue buildup.

Q: Can I observe the phase separation easily with this funnel?

A: Yes, the high transparency of borosilicate glass ensures clear visibility of the interface between separated liquid phases, aiding in precise and efficient separations.
