How Does It Compare with Other JLab Clamps?
| Model | Fingers | Listed construction |
|---|---|---|
| This clamp (EL-SLE-4709) | Four | Aluminium pressure die casting; rubber-covered jaws; iron and brass screws; JLab brand or regular quality |

Four fingers spread the grip around wide or irregular items such as large flasks and condensers, which is where this clamp is most useful. The three-finger clamp suits smaller necks, the four prong clamp is the plated-steel alternative, and the Fisher-type clamp is the choice for holding a burette.
What Is the 4 Finger Retort Clamp Used For?
In chemistry and general science labs, the clamp is fixed to a retort stand rod, normally through a boss head, to hold round-bottom and conical flasks over a burner, condensers during distillation, separating funnels, large test tubes and gas jars, and odd-shaped items that a two-jaw clamp cannot grip securely. School practicals that need a flask or condenser held steady — preparing gases, distillation, and heating liquids — and college organic chemistry set-ups all rely on clamps of this kind.
Close the jaws until the glass is held without forcing it, since glass can crack under point pressure, and grip a flask by its neck rather than its body when it will be heated. Keep the rubber covering away from the flame and hot surfaces.
What to Specify When Ordering
- Grade — JLab brand or regular quality.
- Quantity — minimum 10 units.
- Stand and boss heads — add retort stand bases, rods and boss heads to the same enquiry if you are equipping complete stands.
Frequently Asked Questions
What is a 4 finger retort clamp used for?
Holding larger glassware and odd-shaped objects firmly on a retort stand, for example flasks, condensers and separating funnels.
What is the clamp made of?
Aluminium pressure die casting, with rubber-covered jaws and iron and brass screws.
Why are the jaws rubber covered?
The rubber gives a firmer grip and cushions the glass, so a flask is less likely to slip or be scratched by bare metal.
How does it differ from the 3 finger clamp?
Both are aluminium die-cast with rubber-covered jaws. This clamp has four fingers and is offered in JLab brand or regular quality; the three-finger clamp is listed in superior quality. Four fingers wrap further round wide or irregular items.
Is a boss head included?
The listing does not say. Boss heads are listed separately, so add one per clamp to your enquiry or ask JLab to confirm what is supplied.
Who manufactures the clamp?
JLab — Jain Laboratory Instruments Pvt Ltd — at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of laboratory stands, clamps, glassware and teaching apparatus, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. Its retort clamps are die-cast and assembled at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers receive them factory-direct, every clamp is visually inspected before dispatch, and repeat orders are made by the same manufacturer. JLab exports worldwide and ships to buyers in every region — for example Gabon in Central Africa, Ethiopia in East Africa, Eswatini in Southern Africa, Nepal in South Asia and Guyana in South America.
