Description

[table id=825 /]

The MEDILAB Coil Condenser, also known as a Graham Condenser, is a high-efficiency laboratory condenser designed for superior vapor condensation in distillation, reflux, and solvent recovery systems. Featuring a tightly wound inner coil for maximum cooling surface area, it provides excellent heat-exchange performance even under demanding laboratory conditions. It is an essential component for chemical synthesis, analytical workflows, and industrial research where high cooling capacity and stability are required.

 Key Features

• High-efficiency cooling coil ensures maximum vapour-to-coolant contact.
• Manufactured from premium Borosilicate Glass 3.3 for durability and thermal shock resistance.
• Superior chemical resistance suitable for organic solvents, acids, and laboratory reagents.
• Leak-proof construction with precision-made ground joints.
• Smooth coolant flow through the outer jacket for stable and uniform heat exchange.
• Crystal-clear transparency for easy observation of condensation.
• Available with glass hose connectors for secure coolant tubing attachment.
• Wide compatibility with standard distillation and reflux assemblies.
