Constructed from borosilicate glass, these dropping funnels withstand temperatures up to 120C and resist corrosion from most acids, bases, and solvents. Each funnel is packed individually in cardboard or bubble wrap, reducing the risk of damage during shipment or storage.

FAQ's of Dropping Funnels:

Q: How do I use a laboratory dropping funnel to control liquid addition during experiments?

A: To use the dropping funnel, fill it with your liquid reagent, attach it securely to your setup using its standard ground joint, and use the stopcock to gradually release the liquid. The graduations help monitor the precise quantity added.

Q: What are the chemical resistance properties of this dropping funnel?

A: The funnel, made from borosilicate glass with either a PTFE or glass stopcock, offers excellent resistance against acids, bases, and most organic solvents, ensuring longevity and reliability during laboratory use.

Q: When is it beneficial to use a dropping funnel in laboratory procedures?

A: Dropping funnels are essential when you require slow, controlled addition of liquids-such as in titration, chemical synthesis, or when mixing reactive substances to prevent sudden reactions or splashes.

Q: Where can I use the laboratory dropping funnel?

A: This dropping funnel is suitable for any laboratory setting, whether academic, industrial, or research, wherever precise liquid addition is required. Its ground joints fit standard laboratory glassware.

Q: What is the typical process for cleaning and maintaining this dropping funnel?

A: Rinse thoroughly after use with suitable solvents or detergents, ensuring the stopcock is also cleaned. For stubborn residues, soaking in appropriate cleaning solutions is recommended. Inspect for cracks or wear regularly before use.

Q: How does the graduated marking on the funnel enhance my workflow?

A: The printed graduations allow you to measure and dispense specific reagent volumes confidently, supporting procedural accuracy in all laboratory experiments and reducing the risk of errors.

Q: What are the benefits of the stopcock material options (PTFE or glass)?

A: PTFE stopcocks offer superior chemical resistance, particularly to aggressive acids and solvents, and smooth flow control. Glass stopcocks provide an all-glass system, preferred for certain applications for purity and compatibility.
