What Is the Jumbo Clamp Used For?
Laboratory clamps grip flasks, condensers, cylinders, gas jars and similar apparatus and hold them steady at the height an experiment needs, usually on a retort stand through a boss head. A jumbo clamp is the choice when the item is too wide for an ordinary clamp, for example a large flask or a wide vessel used in a distillation or gas-preparation set-up. Tighten the clamp only enough to hold glass firmly, keep the load over the base of the stand so it cannot tip, support heavy vessels from below as well, and leave a little play when clamping glass that will be heated, because it expands as it warms.
What to Specify When Ordering
- Size — the widest diameter you need to hold, so JLab can confirm the clamp suits it.
- Stand fittings — add boss heads, stand bases and rods if the clamps are for new stands.
- Quantity — the minimum order is 10 clamps.
Frequently Asked Questions
What is a jumbo clamp used for?
It holds larger flasks, cylinders and other apparatus on a laboratory stand, where a standard-size clamp would not open wide enough.
What size of item will it hold?
The jaw opening is not stated in the listing. Give the diameter of the widest item you need to clamp in your enquiry and JLab will confirm the fit.
Does it come with a boss head?
The listing does not say. JLab lists a retort boss head separately, which fixes a clamp to the upright rod of a retort stand, so add it to the order if you need one.
How is it different from the 3-finger and 4-finger retort clamps?
Those listings describe aluminium die-cast clamps with rubber-covered jaws for larger glassware. This listing gives no material or jaw details, so ask JLab to compare them for your use.
Who manufactures the jumbo clamp?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of laboratory stands, clamps and school science equipment in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. This clamp is made in JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers are supplied directly by the manufacturer, each clamp is checked by eye before packing, and repeat orders are handled at the source. JLab exports worldwide and ships to buyers in every region — for example Laos in Southeast Asia, Madagascar in East Africa, Tajikistan in Central Asia, Brazil in South America and Taiwan in East Asia.
