Laboy Glass Allihn Condenser with 24/40 Standard Taper Joints, 400mm Length, Borosilicate 3.3 Reflux Condenser with 10mm Glass Hose Connections

This long-length Laboy Allihn condenser features 24/40 standard taper joints and an effective length of about 400mm, providing a very generous cooling path for more demanding reflux or distillation operations. The sequence of spherical bulbs inside the vapor tube greatly expands surface area, allowing vapors to condense efficiently even for higher-boiling solvents or larger flasks. It is a good choice as a main condenser in teaching and research laboratories where robust, water-cooled performance is required. The condenser is hand-blown from borosilicate 3.3 glass, giving chemical durability, good thermal shock resistance and clear visibility of condensate. Top outer and bottom inner 24/40 joints interface directly with standard 24/40 glassware. Fixed 10mm serrated glass hose connections are appropriately sized for this large condenser and work with common medium-bore tubing from tap-water or recirculating chillers.

• Long 400mm Allihn reflux condenser provides a very long cooling path and high surface area for demanding organic chemistry applications.
• 24/40 standard taper top outer and bottom inner joints connect to common larger-scale flasks, adapters and Soxhlet extractors.
• Spherical bulb design increases vapor–liquid contact area and greatly improves condensation efficiency over straight condensers.
• Fixed 10mm serrated glass hose connections sized for 24/40 condensers; compatible with typical coolant tubing for water-cooled use.
• Borosilicate 3.3 hand-blown glass ensures clarity, chemical resistance and resistance to thermal shock in routine laboratory service.
