Laboy Glass Graham Condenser,Coiled Inner Tube Style, 14/20 Joints, 120 mm Jacket Length, 8 mm Glass Hose Connections, Heavy-Wall Borosilicate 3.3 Lab Glassware for Distillation & Reflux

The borosilicate glass graham condenser consists of an inner coil to condense vapors and an outer jacket through which the coolant flows. With 8mm hose connections accommodate 6mm tubing for cool water in and out. Laboy glass are all made of high-quality borosilicate glass and made by hand-blowing to ensure uniform wall thickness.

• Coiled Graham (Inland Revenue) condenser for efficient condensation in small-scale distillation and reflux; long internal coil and water jacket give an extended vapor path and strong cooling compared with a simple Liebig condenser.
• 120 mm jacket length with 14/20 standard taper joints at top (outer) and bottom (inner drip tip); ideal for microscale and teaching-lab setups using small 14/20 round-bottom flasks.
• Equipped with fixed glass hose connections sized for coolant tubing around 8 mm I.D.; serrated ends grip flexible tubing securely and support counter-current cooling from the lower to the upper port.
• Hand-blown from heavy-wall borosilicate 3.3 glass and carefully annealed for improved durability, thermal-shock resistance and chemical resistance to common organic solvents and reagents.
• Precision-ground joints are compatible with other Laboy 14/20 jointed glassware, allowing this condenser to integrate easily into modular distillation and reflux assemblies in teaching and research laboratories.
