Choose this listing when you want to equip a lab with a mix of basic clamps — a rod-mounted retort clamp in packs of 5 plus 2- and 3-prong utility clamps. The finger clamps state an aluminium die-cast body and rubber-covered jaws, which this listing does not, so pick them if a lined grip on glass is a requirement.
What Are the Clamps Used For?
A retort clamp holds apparatus at a fixed height: its rod goes into a boss head on the stand, and the jaws close around the glassware. Typical uses are holding a flask over a burner during the preparation of a gas in class 10 and class 11 chemistry, holding a condenser in a distillation set-up, steadying a boiling tube or test tube while it is heated, and supporting a thermometer in physics heat experiments. A 2-prong utility clamp suits test tubes and narrow items, while a 3-prong clamp centres round flasks and condensers more evenly.
Tighten the clamp until the glass is just held — overtightening cracks glassware, especially once it is hot — and let heated apparatus cool before you release it. The 8 mm rod of the retort clamp fits JLab’s Boss Head, which takes rods up to 16 mm.
What to Specify When Ordering
- Clamp type — retort clamp, 2-prong or 3-prong utility clamp, or prong clamp, and the number of each.
- Quantity — the minimum order is 10 units; the retort clamp is packed in fives.
- What the clamps must hold — give the widest flask or condenser diameter so the jaw opening can be confirmed.
- Boss heads and stand rods — add them to the same enquiry so each stand is complete.
Frequently Asked Questions
What does this clamps listing include?
A retort clamp on an 8 mm metal rod, supplied in packs of 5, plus utility clamps with 2 or 3 prongs and prong clamps. State which types you need and how many of each.
Will the retort clamp fit my boss head?
It has an 8 mm diameter rod, so it fits any boss head that accepts that size, including JLab’s zinc alloy Boss Head for rods up to 16 mm.
Should I choose a 2-prong or a 3-prong clamp?
A 2-prong clamp is fine for test tubes and narrow items. A 3-prong clamp grips round flasks and condensers from three sides, so it holds them more centrally and securely.
Are the jaws lined?
The listing does not state the jaw lining or body material. If you need rubber-covered jaws, the 3-finger and 4-finger retort clamps linked here list them, or ask JLab about this listing.
Are stands and boss heads included?
No. These are the clamps only; boss heads, stand rods and bases are separate items and can be quoted together.
What should an export quotation request include?
The clamp types and quantities, the destination country and port or city, preferred delivery terms such as FOB or CIF, packing or labelling instructions, and any tender reference.
Who manufactures these clamps?
JLab — Jain Laboratory Instruments Pvt Ltd — makes them at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory equipment manufacturer in India incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. Its clamps are made in its own works instead of being bought from traders, so schools, colleges, dealers and importers deal directly with the factory, each clamp is visually inspected before packing, and repeat or matching orders come from the same source. JLab exports worldwide and ships to buyers in every region — for example Australia in Oceania, the Dominican Republic in Central America and the Caribbean, Sweden in Northern Europe, Mexico in North America and Tanzania in East Africa. For tender purchases, see the JLab lab tenders page.
