Reliable Chemical Handling

Constructed from high-quality glass, these cylindrical dropping funnels offer excellent chemical resistance, making them ideal for working with acids, solvents, and other reactive substances. The transparent body provides clear visibility of contents, supporting accurate monitoring and transfer during experiments.

Precision and Versatility in the Lab

Featuring standard taper ground cone joints (such as 19/26 and 24/29), the funnels ensure secure and universal fit with other laboratory apparatus. The open stopcock stemavailable in glass or PTFEallows for smooth, controlled dispensing or separation of liquids, enhancing experimental accuracy.

Autoclavable and Easy to Clean

Designed for repeated laboratory use, these dropping funnels are fully autoclavable, ensuring effective sterilization and contamination prevention. The robust glass construction withstands high temperatures, making routine cleaning and maintenance straightforward for reliable long-term usage.

FAQs of Dropping Funnels Cylindrical,Open Stopcock Stem With Cone:

Q: How do I use a cylindrical dropping funnel with an open stopcock stem?

A: To use, attach the funnels cone joint securely to the receiving flask. Place your solution in the funnel. Adjust the glass or PTFE stopcock to regulate the flow of liquid dropwise or in a controlled stream, ideal for titration or gradual reagent addition.

Q: What materials are these dropping funnels made from?

A: These funnels are constructed from chemical-resistant transparent glass, with the stopcock made from either glass or PTFE. This ensures durability and compatibility with a wide range of laboratory chemicals.

Q: Are cylindrical dropping funnels autoclavable?

A: Yes, the product is autoclavable, allowing for thorough sterilization at high temperatures. This is essential for maintaining cleanliness and preventing contamination in laboratory processes.

Q: When is it appropriate to use a dropping funnel in the lab?

A: Dropping funnels are most suitable for controlled addition of liquids, such as during titration, or when mixing reagents that require careful, gradual combination to avoid sudden reactions.

Q: What cone joint sizes are available for these funnels?

A: Commonly available cone joint sizes include 19/26 and 24/29, compatible with many laboratory apparatus. Always choose the size that matches your existing glassware setup for a secure fit.

Q: What are the benefits of using a PTFE stopcock over a glass one?

A: PTFE stopcocks offer superior chemical resistance and a smoother, more precise control of liquid flow, even with aggressive or viscous chemicals. They are also less prone to sticking compared to traditional glass stopcocks.
