Jlab Export is a leading Funnel Manufacturer,and suppliers in India
Funnel (code EL-SLE-5674) is a graduated dropping funnel in borosilicate glass with an open top, used to add a liquid reagent gradually to a reaction flask in college and university chemistry labs and in school demonstrations. It is listed in 100 ml, 250 ml and 500 ml capacities, and the graduations let the user see how much liquid has been added. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Addition Funnels?
| Listing | Capacities | Other listed details |
|---|---|---|
| This dropping funnel (EL-SLE-5674) | 100, 250 and 500 ml | Borosilicate glass; open top; graduated; joints not stated |
| Cylindrical Funnels, Plain Stem | 25 ml to 500 ml | Cylindrical body; plain stem; ground socket size listed for each capacity |
| Pressure Equalising Funnels, Pear Shaped | 100 ml and 250 ml | Pear-shaped body; socket and cone sizes listed for each capacity |
Choose this open-top funnel for simple additions where a ground-glass joint is not needed or not specified. For a sealed apparatus, the cylindrical funnels state their socket sizes, and a pressure equalising funnel keeps the pressure above the liquid equal to that in the flask so the liquid keeps flowing in a closed set-up.
What Is a Dropping Funnel Used For?
A dropping funnel holds a liquid above a reaction flask and lets it run in slowly through the tap at its base, so a reagent can be added a little at a time while the reaction is watched. This matters when a reaction gives off heat or gas quickly, for example when an acid is added to a solid to prepare a gas, or when a reagent has to be added dropwise in an organic preparation. Because the top is open, air enters as the liquid runs out and the flow does not stall. Borosilicate glass stands up to the heat and chemicals met in this work better than soda glass.
Clamp the funnel firmly above the flask rather than letting it rest on the neck, keep the tap closed while you fill it, and open the tap gradually to set the drop rate. The graduations give an approximate guide to the volume added; for exact volumes use a burette or pipette. Rinse the funnel after use and store it with the tap open if it has a glass key, so it does not seize.
What to Specify When Ordering
- Capacity — 100 ml, 250 ml or 500 ml, and the number of each.
- Tap and stem — the listing does not describe the stopcock, stem or joint; tell JLab what your flask or apparatus needs so it can confirm the fit.
- Quantity — the minimum order is 10 units.
- Flasks and clamps — add the reaction flasks, stands and clamps to the same enquiry.
Frequently Asked Questions
What capacities is this dropping funnel available in?
Three: 100 ml, 250 ml and 500 ml, all in graduated borosilicate glass with an open top.
What does open top mean?
The top of the funnel is left open rather than closed by a stopper or joint. Air can enter as the liquid drains, so the flow continues steadily, but the funnel is not suited to sealed systems.
Does it have a ground-glass joint and stopcock?
The listing does not describe the stopcock, stem or any joint. Ask JLab to confirm these details before ordering if the funnel must fit a particular flask.
How is a dropping funnel different from a separating funnel?
A dropping funnel is built to feed a liquid into another vessel at a controlled rate; a separating funnel is shaped to let two immiscible liquids settle into layers so they can be drawn off separately.
Who manufactures this dropping funnel?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of borosilicate laboratory glassware and teaching lab equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The dropping funnel is made at JLab’s own works, not bought from a trader, so colleges, schools, dealers and importers buy it factory-direct, each piece is visually checked before dispatch, and repeat orders are handled by the maker. JLab exports worldwide and ships to buyers in every region — for example Barbados in Central America and the Caribbean, Tajikistan in Central Asia, Malawi in East Africa, Uruguay in South America and Slovakia in Eastern Europe. For tenders, see the JLab lab tenders page.
