FAQs of Pressure Equalising Funnels, Cylindrical:

Q: How do I use the pressure equalising funnel for controlled liquid transfer in the laboratory?

A: To use the pressure equalising funnel, attach it to a compatible apparatus via the standard ground glass joint. Open the PTFE stopcock to allow precise transfer or addition of liquids. The design enables both safe transfer and pressure equalisation to prevent splashing and ensure accuracy.

Q: What materials are used in the construction of this funnel, and what benefits do they offer?

A: This funnel is made from borosilicate glass, which provides high chemical and thermal resistance, and features a PTFE (Teflon) stopcock and optional stopper. These materials enhance durability, offer broad chemical compatibility, and withstand temperatures up to 400C.

Q: Where is this equipment typically used within the laboratory context?

A: These pressure equalising funnels are utilized in chemical, biological, and pharmaceutical laboratories across India and globally. They serve essential roles in precise liquid transfer and controlled reagent addition during analytical and preparative procedures.

Q: What makes the stopcock and joint connection reliable for repetitive use?

A: The stopcock is constructed from PTFE for excellent chemical resistance and minimal wear, ensuring smooth operation and leak-free performance. The ground glass joint guarantees a secure, standard fit for repeated assembly and disassembly in various laboratory setups.

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

A: The funnel should be autoclaved prior to use for sterile applications or after use for effective decontamination. It is safe to autoclave at 121C, making it suitable for demanding sterile laboratory protocols.

Q: What are the advantages of having clear and durable graduation markings?

A: Clear and durable graduation marks provide high measurement accuracy, supporting precise volume determination for sensitive experiments. The marks remain intact over extended use, maintaining consistent performance and result reliability.
