About DROPPING FUNNELS

A dropping funnel is a type of laboratory glassware used to transfer fluids. They are fitted with a stopcock which allows the flow to be controlled. Dropping funnels are useful for adding reagents slowly, i.e. drop-wise

Engineered for Laboratory Precision

Dropping funnels are designed to deliver unparalleled accuracy in liquid measurement and reagent addition. The presence of clear graduation markings and manually controlled stopcock valves permits highly controlled flow rates. Manufactured from borosilicate glass or PTFE, these funnels provide reliability and durability for a range of scientific applications, including chemical synthesis and titration procedures.

Versatile and Robust Construction

These dropping funnels are available in various sizes and configurations to suit diverse laboratory needs. Their borosilicate glass build tolerates rapid temperature changes and aggressive chemicals. The combination of a leak-proof design and chemical-resistant stopcock ensures both safety and operational stability during use with acids, alkalis, or solvents.

FAQs of DROPPING FUNNELS:

Q: How do I use a dropping funnel with a stopcock for precise liquid dispensing?

A: To use the dropping funnel, fill it with the desired liquid, secure it onto the reaction vessel using the standard ground glass joint, and adjust the stopcock valve to control the flow rate. The graduation markings help you monitor and dispense the required quantity accurately.

Q: What advantages does a PTFE or glass stopcock provide in a dropping funnel?

A: PTFE and glass stopcocks offer high chemical resistance and reliable leak-proof performance, ensuring compatibility with a wide range of laboratory reagents. PTFE is especially resistant to aggressive chemicals, reducing maintenance and contamination risks.

Q: When should I choose a dropping funnel in laboratory procedures?

A: Dropping funnels are ideal for titrations, gradual reagent additions, or any process that requires controlled and accurate liquid transfer. They are particularly useful when precise dosing is essential, such as during chemical synthesis or analytical experiments.

Q: Where can these dropping funnels be used?

A: Dropping funnels are commonly used in educational, industrial, and research laboratories across chemistry, biology, and material science disciplines. They are widely supplied and manufactured in India and globally.

Q: What are the safety benefits of using this dropping funnel design?

A: The funnels feature a chemically resistant, leak-proof stopcock, and can be autoclavable for sterilization. These attributes minimize exposure to hazardous chemicals, reduce spills, and enhance laboratory safety overall.

Q: How do the graduation markings benefit laboratory work?

A: Graduation markings on these dropping funnels enable precise measurement and delivery of liquids, supporting high-accuracy experiments and ensuring reproducibility of laboratory results.
