Straight Cooler (Condenser)

Product Code : SCL-CL-11479

Straight Cooler (Condenser) (SKU SCL-CL-11479) is a Liebig-type glass condenser, 480 mm long, in which cold water flowing through an outer jacket cools and condenses vapour passing along the straight inner tube. It is the core of simple distillation and reflux set-ups in school, college and training chemistry labs. Science Lab Supplies sources and ships it from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.

Specifications

This straight condenser follows the Liebig pattern and measures 480 mm, a length that gives a long cooling path for water and common solvents. The transparent glass is heat and chemical resistant, so students can watch condensation happen inside the tube.

Applications and Experiments for the Straight Cooler (Liebig Condenser)

The condenser is used to turn vapour back into liquid during distillation, and, fitted vertically, to return vapour to a boiling flask during reflux. It supports separation and purification practicals from Class 9 science to B.Sc. organic chemistry and small-scale water distillation.

• Class 9 science: separating acetone and water, or another pair of miscible liquids, by distillation.
• Class 11 chemistry: purifying an organic liquid by simple distillation.
• B.Sc. organic practicals: refluxing reaction mixtures and distilling off solvents.
• Water treatment topics: preparing distilled water and discussing why it is used in labs.

Connect the cooling water so it enters at the lower inlet and leaves at the upper outlet; this keeps the jacket full. Clamp the condenser securely and never heat a closed system.

Standard Scope of Supply

The Straight Cooler (Condenser) is supplied as a single 480 mm Liebig-type glass condenser, as described above. Rubber tubing for the water supply, clamps, flasks and the receiver adapter are separate items that can be added to your quotation.

Packing, MOQ and Lead Time

We quote condensers singly as replacements or in sets for a full distillation practical. Your quotation states the packing, delivery time and price for the quantity, and other laboratory distillation apparatus in India such as flasks, adapters and tubing can be quoted with it.

Science Lab Supplies is a registered exporter with an Importer-Exporter Code, able to ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Questions and orders can come through the contact page or the enquiry cart; for public procurement, see the lab tender page.

Frequently Asked Questions

What is a straight cooler?
It is another name for a Liebig condenser: a straight glass tube inside a water jacket. Vapour passing through the inner tube is cooled by the circulating water and condenses to liquid.

How long is this condenser?
It is 480 mm long, which provides a long cooling section for distillation and reflux of water and common organic solvents in teaching labs.

Who supplies the Straight Cooler (Condenser)?
Science Lab Supplies supplies it from Ambala, India, and prepares quotations and shipments for schools, colleges, tender contractors and distributors.

What else do I need for a distillation set?
A boiling flask, a stand with clamps, rubber tubing for the cooling water, a receiver adapter and a receiving flask. All of these can be quoted together with the condenser.

Related Distillation Apparatus

A condenser works only as part of a train: flask, condenser, adapter and receiver, with tubing for the cooling water. These four items complete that train for chemistry lab equipment in India buyers and can be ordered on one quotation.

• Adapter (Alunge) — 150 mm glass adapter linking the condenser to the receiver.
• Liebig Condenser 200mm — shorter condenser for compact set-ups.
• Distillation Pot with Side Funnel 250ml — boiling flask for the heated side.
• Rubber Tube (Laboratory) — tubing for the cooling-water inlet and outlet.
