How Does It Compare with Other JLab Long-Stem Funnels?
| Listing | Material | Listed details |
|---|---|---|
| This funnel (EL-SLE-5675) | Soda lime glass | Straight stem, or bent stem with 2 safety bulbs, 300 mm long |
| Thistle Funnel | Glass, stout-walled | Pitcher-shaped head on a 300 mm stem; for gas preparation and osmosis demonstrations |

Choose this funnel when you want the safety-bulb form for gas preparation or a plain long straight stem in economical soda lime glass. A thistle funnel has a rounded head instead of a cone, and the Funnel with Long Tube is a borosilicate filter funnel for filtration rather than for feeding a reaction.
What Is a Long-Stem Safety Funnel Used For?
In a school gas-preparation set-up, the funnel stem passes through a cork into the generating flask and dips below the liquid, so acid can be poured in without the gas escaping back up the stem. The two safety bulbs on the bent-stem form hold a little liquid that acts as a seal and catches splashes if the reaction froths up. A long straight stem also lets you deliver a liquid to the bottom of a tall vessel without wetting its sides. Set-ups like this are standard in school and college chemistry demonstrations where a gas is made and collected.
Fit the stem through a bored cork or bung with a little water or glycerol as a lubricant, twisting gently and holding the stem close to the cork to avoid snapping it. Soda lime glass is not meant for strong heating or sudden temperature changes, so keep the funnel away from direct flame and wash it with warm, not boiling, water.
What to Specify When Ordering
- Form — straight stem or bent stem with two safety bulbs, and how many of each.
- Stem length — confirm the straight-stem length with JLab before ordering.
- Quantity — the minimum order is 10 units; corks and flasks can be quoted alongside.
Frequently Asked Questions
What forms of this funnel are available?
Two: a straight-stem funnel and a bent-stem funnel with two safety bulbs. Both are soda lime glass; the bent safety-bulb version is listed as 300 mm long.
What are the safety bulbs for?
They hold a small amount of liquid in the stem, which acts as a seal against gas escaping and traps splashes from a vigorous reaction before they reach the user.
How long is the straight stem?
Please confirm it with JLab. The listing’s figure for the straight stem is being checked, so ask for the length when you request a quotation.
Can this funnel be heated?
It is not intended for direct heating. Soda lime glass handles room-temperature and warm liquids well but is more sensitive to sudden temperature changes than borosilicate glass.
Who manufactures this 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, a school and college lab glassware manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The funnel is produced in JLab’s own works instead of being bought from a trader, so schools, colleges, dealers and importers order direct, each funnel is checked visually before it is packed, and repeat orders go back to the same works. JLab exports worldwide and ships to buyers in every region — examples include Turkmenistan in Central Asia, Cameroon in Central Africa, Armenia in Eastern Europe, the USA in North America and Guyana in South America. Tender buyers can use the JLab lab tenders page.
