The MEDILAB Liebig Condenser is a straight-tube laboratory condenser designed for efficient cooling and condensation of vapours during distillation and reflux operations. Manufactured from premium Borosilicate Glass 3.3, it ensures excellent thermal stability and chemical resistance. Its simple yet highly effective design makes it an essential component in organic synthesis, chemical processing, academic research, and QA/QC laboratories worldwide.

Key Features

• Constructed from high-quality Borosilicate Glass 3.3 for superior durability and heat resistance.
• Straight condenser design ensures consistent coolant flow and efficient vapour condensation.
• Uniform wall thickness enhances mechanical strength and minimises thermal stress.
• Highly transparent glass enables clear visibility of internal processes.
• Chemical-resistant material suitable for acids, solvents, and organic reagents.
• Available with standard ground-glass joints for leak-free, secure connections.
• Compatible with a wide range of laboratory setups and distillation apparatus.
• Easy to clean, maintain, and integrate into modular glassware assemblies.
