Robust Chemical Resistance

The use of high-quality borosilicate glass for the funnel body and PTFE for the key and stopcock gives these separating funnels outstanding compatibility with a variety of chemicals, including strong acids, bases, and organic solvents. This makes them exceptionally versatile for laboratory use where exposure to harsh substances is common.

Precision and Ease of Use

Graduated with clear, permanent volume markings, these funnels enable accurate measurement and separation. The PTFE key ensures smooth manual control over the liquid flow, providing reliability and safety during extractions, while the glass/ground joint maintains a secure and leak-proof seal.

Sterilizable and Reusable

Engineered for repeated use, these separating funnels are fully autoclavable for easy sterilization. Their robust materials withstand thermal cycling, ensuring long-term durability and performance. Easy to clean and maintain, they offer cost efficiency and environmental benefits for laboratories.

FAQs of Separating Funnels, with PTFE Key:

Q: How is the PTFE key beneficial for separating funnels in laboratory applications?

A: The PTFE (Polytetrafluoroethylene) key offers superior chemical resistance, smooth operation, and ensures leak-proof separations, making it ideal for handling a wide range of aggressive acids, bases, and organic solvents commonly used in laboratories.

Q: What is the recommended sterilization process for these separating funnels?

A: These funnels are autoclavable, meaning they can be sterilized in a standard laboratory autoclave at appropriate temperatures and pressures. Always ensure the PTFE stopcock is loosely positioned to prevent pressure buildup during the process.

Q: When should I use a separating funnel with a PTFE key?

A: Separating funnels with PTFE keys should be used whenever high chemical resistance, precision in liquid-liquid extraction, and safe, contamination-free operation are required, such as in analytical chemistry, organic synthesis, and industrial laboratories.

Q: Where can these separating funnels be effectively utilized?

A: These funnels are suitable for use in research laboratories, educational institutions, industrial testing facilities, and any setting that requires precise handling of immiscible liquid phases, especially where aggressive chemicals are present.

Q: What is the process of cleaning and maintaining these separating funnels for reuse?

A: After use, disassemble the funnel and wash it thoroughly with compatible cleaning agents. Both the borosilicate glass and PTFE key can be rinsed with distilled water and dried, ensuring all residues are removed before reuse.

Q: What benefits do the permanent graduation markings provide?

A: The clear, permanent graduations on the funnel body allow for precise and repeatable measurement of liquids during separations, increasing accuracy and minimizing user errors in laboratory procedures.
