Fractionating Column Manufacturer,Supplier and Exporter in India

Product Code : EL-SLE-5664
Jlab Export is a leading Fractionating Column Manufacturer,and suppliers in India

Fractionating Column (code EL-SLE-5664) is a rod and disc type column in borosilicate glass, used in fractional distillation to separate miscible liquids with close boiling points in school, college and university chemistry labs. A removable centre rod carries 20 discs inside a smooth-bore tube, so the rod and discs can be taken out for cleaning. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Specifications

How Does It Compare with Other JLab Fractional Distillation Glassware?

Choose this column when you want a rod-and-disc column to add to glassware you already have. The Fractional Distillation Column listing describes the same design and states its length, so compare the two if length matters; the assembly suits labs that want a complete set built around a Vigreux column rather than discs.

What Is a Fractionating Column Used For?

In fractional distillation the column stands upright between the boiling flask and the condenser. Vapour rising from the flask condenses and re-evaporates again and again on the discs as it climbs, so the vapour that reaches the top is richer in the more volatile liquid; it then passes into the condenser and is collected. This separates miscible liquids whose boiling points are close more cleanly than simple distillation, and it is the same principle a refinery uses to split crude oil into fractions. Students meet the method in class 9 science when separating miscible liquids and again in class 11 chemistry purification techniques, and college organic chemistry labs use it for teaching and solvent purification.

Clamp the column vertically on the flask, place a thermometer at the top so the vapour temperature can be read, and heat gently so the vapour climbs slowly; heating too fast floods the column and spoils the separation, and wrapping the column with insulation reduces heat loss. Let the glass cool before washing, then draw out the centre rod to clean the discs and the bore.

What to Specify When Ordering

• Length and joints — this listing does not give the overall length, joint size or side connection; say what your flask and condenser use so JLab can confirm the fit.
• Quantity — the minimum order is 10 columns; many labs order one per distillation set plus a spare.
• Matching glassware — add boiling flasks, condensers, thermometers and clamps to the same enquiry so each set is complete on delivery.

Frequently Asked Questions

What is a fractionating column used for?
It improves the separation of miscible liquids with close boiling points during fractional distillation. Fitted between the boiling flask and the condenser, it gives the rising vapour many chances to condense and re-evaporate, so the distillate collected is richer in the more volatile liquid.

How many discs does this column have?
Twenty. The listing describes a removable centre rod carrying 20 discs inside a smooth-bore borosilicate glass tube, which is why it is called a rod and disc type column.

What is the length and joint size of this column?
They are not stated in this listing. Ask JLab to confirm the overall length, the end joints and the side connection before you order, especially if the column must fit flasks and condensers you already have.

How is a rod and disc column different from a Vigreux column?
A Vigreux column has indentations formed in its glass wall, while this design uses separate discs on a centre rod. Because the rod is removable, the discs and the inside of the tube can be cleaned separately.

Are the flask, condenser and thermometer included?
No. This listing covers the fractionating column only; boiling flasks, condensers, thermometers and clamps are separate items and can be quoted in the same enquiry.

Who manufactures this fractionating column?
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 manufacturer of borosilicate glassware and school lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This column is produced at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers order it factory-direct, every piece is visually inspected before dispatch, and repeat orders and replacement parts are handled by the maker. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — Mali in West Africa, Papua New Guinea in Oceania, Austria in Western Europe, Estonia in Northern Europe and Uzbekistan in Central Asia are examples. Institutions buying through tenders can find details on the JLab lab tenders page.

Distillation Glassware

• Fractional Distillation Column — the same rod-and-disc design, listed with its overall length and side entry tube.
• Fractional Distillation Assembly — a complete borosilicate set with Vigreux column, Liebig condenser and flasks.
• Liebig Condenser — a borosilicate condenser that cools and condenses the vapour leaving the column.
• Condensers — a borosilicate condenser with a narrow fused-on cooling jacket.
• Round Bottom Flask — a heat-resistant borosilicate boiling flask for the bottom of the set.
