The Glass Liebig Condenser is a water-cooled laboratory condenser used for cooling hot vapour and converting it back into liquid during distillation and related laboratory procedures. It is intended for school, college, university, chemistry, and research laboratories requiring a simple straight-path condenser for controlled vapour condensation.
Product Description
The STEMAids Glass Liebig Condenser uses the established Liebig condenser design: a straight inner vapour tube surrounded by an outer cooling-water jacket. Vapour travels through the inner tube while circulating water removes heat through the surrounding jacket, causing suitable vapours to condense into liquid.
For efficient operation, cooling water is normally connected to the lower jacket inlet and allowed to leave through the upper outlet. This arrangement helps keep the jacket filled with coolant. The exact STEMAids glass grade, jacket length, overall length, joint configuration, and hose-connection size are. Related equipment can be found under Laboratory Glassware and General Lab Products.
Key Features
- Straight-path condensation: Provides a direct inner tube for vapour flow and condensate recovery.
- Water-cooled jacket: Circulating coolant around the inner tube removes heat from passing vapour.
- Suitable for distillation: Supports laboratory separation procedures involving vaporisation followed by condensation.
- Continuous cooling: Lower-inlet and upper-outlet water flow helps maintain effective jacket filling.
- Visible process: Glass construction allows users to observe vapour condensation and liquid movement.
- Reusable laboratory format: Designed for repeated use when cleaned and handled according to laboratory procedures.
- Critical specifications: Glass grade, joint size, jacket length, and connection dimensions are.

How to Use the Glass Liebig Condenser
- Inspect the condenser for cracks, chips, blocked passages, or damaged joints.
- Mount the condenser securely using appropriate laboratory supports and clamps.
- Connect the lower water-jacket port to the cooling-water supply.
- Connect the upper port to a suitable drain or return line.
- Start a controlled cooling-water flow and confirm that the jacket fills without leaking.
- Connect the condenser to the distillation apparatus using the specified joints or adapters.
- Heat the sample only according to the approved experimental procedure.
- Observe condensate formation and collect the condensed liquid in the designated receiving vessel.
Safety note: Never seal a heated distillation system completely. Secure all glassware, inspect coolant tubing before heating, and keep water connections away from electrical equipment. Do not assume a specific maximum operating temperature or vacuum rating until the STEMAids glass and joint specifications are confirmed.
Care & Maintenance
- Rinse and clean the inner vapour path promptly after use to prevent residue buildup.
- Flush the cooling jacket with clean water and drain it before storage.
- Inspect joints and hose connections for chips, cracks, mineral deposits, or blockage.
- Store the condenser with adequate support so the side arms and glass joints are protected from impact.

Frequently Asked Questions
What is a Glass Liebig Condenser used for?
A Glass Liebig Condenser is used to cool hot vapour and convert it back into liquid, particularly during laboratory distillation procedures.
How does a Liebig condenser work?
Hot vapour travels through the straight inner tube while cooling water circulates through the surrounding outer jacket. Heat transfers from the vapour to the coolant, causing the vapour to condense.
Which direction should water flow through a Liebig condenser?
Cooling water should normally enter through the lower jacket connection and leave through the upper connection. This helps fill the cooling jacket continuously and improves heat exchange.
Can a Liebig condenser be used for distillation?
Yes. Distillation is one of the principal applications of a Liebig condenser because it provides a simple water-cooled path for converting separated vapour back into liquid.
What glass is the STEMAids Liebig Condenser made from?
The product is made from glass, but the exact glass grade is. Borosilicate 3.3 or another specific composition should not be claimed until verified.
Can the STEMAids Liebig Condenser be used under vacuum?
Vacuum compatibility is. Do not use the condenser under reduced pressure unless its glass construction, joints, wall thickness, and vacuum rating are confirmed for that application.
