Frequently Asked Questions

Which retort clamp should I choose for a flask or condenser?
Three- and four-prong clamps are the usual choice for flask necks and condensers because they close around round glassware. A standard clamp suits test tubes and smaller items.

What is the difference between cork jaws and rubber jaws?
Both linings cushion the glass so it is not held metal-to-glass. Which one a laboratory prefers is largely a matter of practice; both are listed with and without a bosshead.

Do the clamps come with a bosshead?
Two versions, the Retort Clamp with Bosshead in cork-jaw and rubber-jaw form, are listed with a bosshead. For the other clamps, add bossheads from the Bosshead range.

Can you supply clamps for every station in a new lab?
Yes. Clamps are quoted in class sets and in bulk for schools, colleges, distributors and tenders, and can be combined with stands and bossheads on one order.

What should a quotation request include?

Retort Clamp Standard 18/10 Stainless Steel

Product Code : SLE/RC/01

Retort Clamp Standard 18/10 Stainless Steel (Product Code: SLE/RC/01) is a round-jaw laboratory clamp used to hold flasks, tubes and other round apparatus on a retort stand. It is made from 18/10 stainless steel in seven sizes, from 150 mm long with a 10 mm shaft and 25 mm span up to 180 mm long with a 12 mm shaft and 150 mm span. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

What Is the Standard Retort Clamp Used For?

A standard retort clamp grips a flask, condenser, test tube or column so it stays steady above a burner or over a collecting vessel. Its shaft locks into a bosshead on a vertical support rod, and the round jaws close around the neck or body of the apparatus. Matching the span to the vessel matters: the 25–60 mm spans suit test tubes and flask necks, while the 80–150 mm spans take larger flasks and columns.

The 18/10 grade of stainless steel is corrosion-resistant and wipes clean after spills, so this clamp is a practical choice for teaching labs, research benches and any chemistry lab equipment set that sees daily use. Tighten the jaws only until the glassware is held firmly, because over-tightening metal jaws can crack glass. Where glass is thin-walled, a strip of rubber or cloth between jaw and vessel spreads the pressure.

What to Specify When Ordering

  • Span d — choose 25, 40, 60, 80, 100, 120 or 150 mm to fit the diameter of your apparatus.
  • Shaft diameter — the 150 mm clamps have a 10 mm shaft and the 180 mm clamps a 12 mm shaft; check that your bossheads accept it.
  • Quantity per size — most labs mix small and large spans, so state the number needed of each.
  • Stand parts — add bossheads and stand bases from the list below if you are equipping new stands.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the original equipment manufacturer (OEM) of this stainless steel retort clamp and makes the full size range at its own licensed factory at Saha, Ambala, Haryana, India.

Retort Clamp Special 3-Prongs, 18/10-Stainless Steel

Product Code : SLE/RC/02

Retort Clamp Special 3-Prongs, 18/10-Stainless Steel (Product Code: SLE/RC/02) is a three-finger laboratory clamp used to hold glassware of different diameters on a support stand. Its stainless steel fingers carry a silicone coating that cushions the glass, and it comes 190 mm long on a 12 mm shaft with a span of 0–80 mm or 0–120 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

ManufacturerJain Scientific Equipments Pvt Ltd (ScienceLab) — OEM
Country of originIndia (made in Ambala, Haryana)

What Is the 3-Prong Special Retort Clamp Used For?

Three fingers close on an object from three directions, centring round-bottom flasks, separating funnels, condensers and columns more naturally than a two-jaw clamp. Because the span opens from zero, the 0–80 mm version holds slim tubes as well as medium flasks, while the 0–120 mm version reaches wider vessels. That range lets one clamp serve many setups in chemistry lab glassware work, from distillation to filtration.

The silicone coating on each finger grips without scratching and spreads the load on glass, cushioning it without extra padding. Mount the 12 mm shaft in a bosshead, position the clamp before tightening, and check that the vessel hangs straight before adding liquid or heat. Keep the coated fingers away from direct flame.

What to Specify When Ordering

  • Span version — 0–80 mm or 0–120 mm, based on the widest vessel you need to hold.
  • Quantity — the number of clamps per bench or per stand.
  • Bossheads — confirm that yours accept a 12 mm shaft, or add stainless bossheads to the order.

OEM Manufacturer

This 3-prong clamp comes from ScienceLab, the trade name of Jain Scientific Equipments Private Limited, which is its OEM and produces it at the company's own licensed factory at Saha, Ambala, Haryana, India. Research laboratories, universities, schools, dealers and importers in India and international markets buy it direct from the manufacturer rather than through a trading house.

The Retort Clamp Special 3-Prongs, 18/10-Stainless Steel is available in two versions, both 190 mm long with a 12 mm shaft: one with a 0–80 mm span and one with a 0–120 mm span.

Why are the fingers of this 3-prong clamp silicone coated?
The fingers of the Retort Clamp Special 3-Prongs carry a silicone coating so they grip glassware firmly without metal-to-glass contact, which helps prevent scratches and spreads the pressure on thin-walled flasks and tubes.

How does the 3-prong special clamp differ from a standard retort clamp?
The Retort Clamp Special 3-Prongs uses three silicone-coated fingers that centre round vessels and open from zero, whereas a standard retort clamp has bare round jaws in fixed span sizes. The 3-prong design suits mixed diameters on one stand.

Product codeSLE/RC/05
ManufacturerJain Scientific Equipments Pvt Ltd (ScienceLab) — OEM
Country of originIndia (made in Ambala, Haryana)

What Is the 4-Prong Special Retort Clamp Used For?

A fourth finger spreads the holding force around more of the vessel, so the clamp resists tilting when it carries a large round-bottom flask, a wide chromatography column or a full separating funnel. The 150 mm size with a 0–120 mm span covers everything from narrow necks to mid-sized bodies, while the two 190 mm sizes reach further from the rod and are set for mid-range (20–100 mm) or wide (50–150 mm) vessels.

Silicone-coated fingers keep metal off the glass and add grip on smooth surfaces. For heavy loads, mount the clamp low on the support rod, tighten the bosshead fully before adding liquid, and keep the coated fingers clear of direct flame. Checking the stand for wobble before starting a long run is a good habit in any teaching or research lab.

What to Specify When Ordering

  • Size — 150 mm with 0–120 mm span, 190 mm with 20–100 mm span, or 190 mm with 50–150 mm span.
  • Vessel range — note the smallest and largest diameters you need to hold.
  • Bossheads — confirm that they accept a 12 mm shaft.
  • Quantity — the number required of each size.

Retort Clamp with Bosshead, Cork Jaws

Product Code : SLE/LC/16

Retort Clamp with Bosshead, Cork Jaws (Product Code: SLE/LC/16) is a diecast alloy laboratory clamp with cork-lined jaws, used to hold flasks, condensers and tubes on a retort stand rod. It comes complete with a bosshead that accommodates rods up to 15 mm in diameter, giving a lab stand clamp and boss head in one item, while the cork lining cushions glassware.

Country of originIndia (made in Ambala, Haryana)

What Is the Cork-Jaw Retort Clamp with Bosshead Used For?

Cork is a traditional jaw lining because it is slightly compressible and a poor conductor of heat, so it moulds gently around a flask neck or condenser and cushions glass that is warm from a heating setup. To mount the clamp, slide the bosshead onto a stand rod of up to 15 mm diameter, tighten it at the working height, then close the cork-lined jaws around the apparatus until it no longer turns.

Because the clamp and bosshead come together, a teacher or technician can equip a new stand in one step, and the diecast alloy body suits everyday school, college and research use as part of a chemistry lab equipment set. Cork liners can dry out over the years, so wipe them with a dry cloth rather than solvents and keep the clamp away from strong heat when stored.

OEM Manufacturer

This cork-jaw clamp is manufactured by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab and acts as its OEM. Production takes place at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414), and finished clamps go directly to laboratories, schools, dealers and importers in India and international markets. Buying from the maker keeps quotations, repeat orders and spare-part questions in one place, so just ask us. More detail is on the ScienceLab company profile.

Retort Clamp with Bosshead, Rubber Jaws

Product Code : SLE/LC/15

Retort Clamp with Bosshead, Rubber Jaws (Product Code: SLE/LC/15) is a rubber-lined diecast alloy clamp used to grip smooth glassware, plastic bottles and tubing firmly on a laboratory retort stand. Its bosshead takes rods up to 15 mm in diameter, and the rubber lining adds friction so smooth, slippery items stay put during room-temperature work.

What Is the Rubber-Jaw Retort Clamp with Bosshead Used For?

Rubber linings give a firm, non-slip hold on smooth and slightly wet surfaces, which makes this clamp a good fit for separating funnels, measuring cylinders, gas jars during collection over water, and plastic bottles or tubing that a hard jaw might dent. The bosshead lets the whole unit be set at any height on a rod of up to 15 mm diameter.

Rubber softens with heat and can swell on contact with some organic solvents and oils, so this version is suited to room-temperature work; for warm glassware the cork-jaw version is the usual choice. Inspect the linings from time to time and clean them with water and a mild detergent rather than solvent. Tighten the bosshead first, then the jaws, so the vessel is never left hanging on a loose clamp.

What to Specify When Ordering

  • Quantity — the number of clamps per stand or bench.
  • Rod diameter — confirm your stand rods are no thicker than 15 mm.
  • Jaw lining — rubber for grip at room temperature, or cork for warm apparatus; many labs order some of each.

OEM Manufacturer

The rubber-jaw clamp is an OEM product of ScienceLab, the trading name of Jain Scientific Equipments Private Limited, and is manufactured at the company's own licensed factory at Saha, Ambala, Haryana, India. Educational institutions, research labs, stockists and importers in India and international markets receive it straight from that factory rather than through a trader. If you need spare parts or a repeat batch to match earlier supplies, the manufacturer handles it directly, so ask us. Background on the company is available on the ScienceLab profile.

Retort Clamp, Cork Jaws

Product Code : SLE/LC/17

Retort Clamp, Cork Jaws (Product Code: SLE/LC/17) is a four-prong laboratory clamp with cork-lined jaws, used to hold items from 2 to 90 mm in diameter, from thin tubes to flasks, on a retort stand. It has a blue coated finish, an overall length of 245 mm and a 145 mm rod, and its jaw design keeps a firm grip at every angle of opening. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Four-Prong Cork-Jaw Retort Clamp Used For?

The wide 2–90 mm range means one clamp can hold a thin tube for one experiment and a mid-sized round-bottom flask for the next, cutting down the number of clamp types a lab has to stock. Four cork-lined prongs close evenly around the item, and because the jaw geometry keeps its grip at all angles of opening, small items are held as firmly as larger ones.

Cork cushions glass and insulates against moderate warmth, and on this clamp the liners are well secured to the jaws, so they stay put through repeated tightening. The 145 mm rod fits into a boss or clamp holder on a retort stand, while the blue coating protects the metal and makes the clamp easy to pick out on a shared bench. Keep the cork away from open flame and wipe it with a dry cloth after use.

What to Specify When Ordering

  • Quantity — the number of clamps needed per stand or bench.
  • Mounting — the clamp fixes by its 145 mm rod, so each one needs a boss or clamp holder on the stand.
  • Largest item — check that your widest vessel is within the 90 mm capacity; for wider items see other clamps in the category.

Retort Clamp, Rubber Jaws

Product Code : SLE/LC/18

Retort Clamp, Rubber Jaws (Product Code: SLE/LC/18) is a laboratory clamp with rubber-lined diecast jaws, used to hold flasks, bottles and tubes up to 90 mm across on a retort stand. It is mounted on a 135 mm rod of 8 mm diameter, measures 250 mm overall, and its clamping rod works through swivels set into the jaws so they settle evenly on the item. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Mounting rod135 mm long, 8 mm diameter
Overall length250 mm
Product codeSLE/LC/18
ManufacturerJain Scientific Equipments Pvt Ltd (ScienceLab) — OEM
Country of originIndia (made in Ambala, Haryana)

What Is the Rubber Jaw Retort Clamp Used For?

A 90 mm jaw capacity covers a wide range of everyday glassware on a student bench, including conical flasks, reagent bottles, measuring cylinders and boiling tubes. The swivels in the jaws let each jaw pivot slightly as the clamping rod is tightened, so the rubber pads sit flat against curved or tapered surfaces instead of pinching at one point.

Before setting up, check that your boss or clamp holder grips an 8 mm rod securely; the 135 mm rod length decides how far the vessel sits from the stand upright. The rubber lining grips smooth glass well but should be kept away from flames, hot plates and prolonged solvent contact. Used this way, it is a common piece of chemistry lab equipment on school and college benches.

Jain Scientific Equipments Private Limited, whose brand is ScienceLab, is the OEM of the Retort Clamp, Rubber Jaws and produces it at its own licensed factory at Saha, Ambala, Haryana, India.
