Liebig Condenser

Product Code : SCL-LG-11987

The Liebig Condenser is a straight, water-cooled laboratory condenser used to cool hot vapours and convert them back into liquid during distillation and related laboratory procedures. This 200 mm model is intended for chemistry laboratories, schools, colleges, universities, and research settings.

Product Description

The Liebig Condenser has a straight inner tube surrounded by a cooling-water jacket. The Science Lab Supplies model has a verified 200 mm jacket length, a narrow jacket for efficient cooling, and an inner tube integral with the body. It is manufactured from borosilicate glass.

During operation, vapour passes through the inner tube while cooling water circulates through the outer jacket. This arrangement removes heat from the vapour and supports condensation. For compatible teaching and laboratory apparatus, explore the chemistry lab equipment collection.

Key Features

• 200 mm jacket length: Provides a compact cooling section for laboratory distillation setups.
• Borosilicate glass construction: Verified material for this Science Lab Supplies model.
• Narrow water jacket: Designed to support efficient cooling around the vapour tube.
• Integral inner tube: The inner tube forms part of the condenser body.
• Straight condenser design: Supports clear observation of vapour condensation and condensate flow.
• Educational and laboratory value: Suitable for demonstrating condensation, distillation, phase change, and heat transfer.

Technical Specifications

What's Included in the Kit

• 1 × Liebig Condenser with 200 mm jacket length.
• Rubber tubing, clamps, stands, flasks, adapters, heating sources, receivers, and other accessories are not included unless specifically confirmed.

Applications / Uses

• Cooling vapours during standard laboratory distillation.
• Condensing evaporated solvent or liquid into a recoverable liquid phase.
• Demonstrating condensation and phase change in chemistry practicals.
• Supporting compatible reflux or extraction setups where a straight water-cooled condenser is specified.
• Use with suitable laboratory flasks in properly assembled distillation apparatus.

How to Use the Liebig Condenser

1. Inspect the glass condenser for cracks, chips, blocked passages, or damaged hose connections.
2. Secure the condenser with appropriate laboratory clamps and connect it to compatible apparatus.
3. Attach the cooling-water inlet to the lower jacket connection and the outlet to the upper connection so the jacket fills effectively.
4. Start a gentle coolant flow before significant vapour reaches the condenser.
5. Heat the distillation flask according to the approved experimental procedure.
6. Observe vapour condensing inside the inner tube and collect the liquid in a suitable receiver.
7. After use, stop heating, allow the apparatus to cool, then shut off the water supply and dismantle carefully.

Safety note: Clamp glassware securely, avoid thermal shock, keep hoses firmly attached, and never operate a sealed distillation system. Use appropriate personal protective equipment and follow the laboratory procedure for the chemicals being handled.

Care & Maintenance

• Rinse the inner tube promptly with a cleaning method compatible with the chemical residue.
• Flush the water jacket when mineral deposits or contamination may affect coolant flow.
• Avoid abrasive tools and sudden temperature changes.
• Store the condenser in a protected rack or padded area to prevent impact damage.

Frequently Asked Questions

What is a Liebig Condenser used for?

A Liebig Condenser is used to cool hot vapours and convert them back into liquid, most commonly during laboratory distillation.

How does a Liebig Condenser work?

Vapour travels through the straight inner tube while cooling water circulates through the surrounding jacket. Heat transfers from the vapour to the coolant, causing the vapour to condense.

What is the size of this Liebig Condenser?

This model has a verified jacket length of 200 mm. Its overall dimensions and joint size should be confirmed before purchase.

What material is this condenser made from?

This Science Lab Supplies Liebig Condenser is made from borosilicate glass, as stated on the current product page.

Which direction should cooling water flow?

For effective jacket filling, connect cooling water to the lower inlet and allow it to exit through the upper outlet.

Can this Liebig Condenser be used in schools and colleges?

Yes. It is suitable for supervised chemistry practicals involving distillation, condensation, phase change, and heat-transfer demonstrations.
