Laboy Glass Graham Condenser, Coiled Inner Tube Style, 19/22 Joints, 200 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 condenser for high-efficiency cooling in organic chemistry distillation or reflux setups; long internal coil and surrounding jacket provide strong, stable condensation.
• 200 mm jacket length with 19/22 standard taper joints at top (outer) and bottom (inner drip tip); suited to typical 50–250 mL 19/22 round-bottom flasks used in teaching and research labs.
• Fixed glass hose connections accept coolant tubing around 8 mm I.D. and support counter-current flow, with coolant entering at the lower port and exiting at the upper port for an efficient temperature gradient.
• Heavy-wall borosilicate 3.3 glass construction provides resistance to thermal shock and chemical corrosion, and clear glass walls make it easy to observe vapor and condensate behavior during operation.
• Precision-ground 19/22 joints seal reliably with Laboy flasks and adapters, allowing this condenser to integrate into modular distillation trains, reflux assemblies and solvent-recovery setups.
