Laboy Glass Coiled Reflux Condenser, Coil Style, 300 mm Jacket Length, 24/40 Joints, 8 mm Glass Hose Connections, Borosilicate 3.3 Lab Glassware for Organic Chemistry

Coiled condenser is the reverse of the Graham Condenser, the coolant flows through the inner coil, and the vapor condenses inside the outer jacket. With 10mm serrated glass hose connections accommodating 8mm I.D. rubber tubing. Laboy glass are all made of high-quality borosilicate glass and made by hand-blowing to ensure uniform wall thickness.

• Coil style coiled reflux condenser for intensive cooling in organic chemistry; the tightly wound inner coil provides a large cold surface so vapors condense quickly and return to the flask for strong, stable reflux.
• 300 mm jacket length with 24/40 standard taper joints, offering increased cooling capacity for roughly 250–600 mL flasks in teaching or research labs.
• Jacketed body has a 24/40 outer joint at the top and a matching inner drip-tip joint at the bottom so condensate returns directly to the reaction mixture instead of running down the joint surface.
• Fixed glass hose connections for coolant tubing around 8 mm I.D.; serrated ends grip standard laboratory tubing and support counter-current coolant flow from the lower to the upper port.
• Hand-blown from heavy-wall borosilicate 3.3 glass with precision-ground joints, offering good thermal shock resistance and reliable sealing with other Laboy 24/40 jointed glassware.
