SOLVENT DISTILLATION APPARATUS, AIRFREE, SCHLENK

Apparatus for use in distillation of material such as THF or ether. Storage reservoir has a capacity of 125mL or 500mL. Extremely efficient cold finger coil condenser has a section that is immersed into the distillate. This assures that the distillate is at room temperature instead of the distillation temperature. The 0-4mm Chem-Vac™ Chem-Cap® valves provide for grease-free, leakproof seals.

Side vapor tube (A) is fitted with a 14/20 standard taper outer joint, to be used with a CG-1042-14 thermometer adapter which fits a plain stem thermometer. A short (50mm) vigreux section is provided to enhance separation. Syringe access port (B) incorporates a 4mm PTFE stopcock with a 14/20 outer joint for use with CG-3022 septum stopper permitting repeated syringe punctures or changes of the septum without breaching the integrity of the solvent. Lower 3-way valve (C) allows for solvent return to flask, take-off or storage in graduated reservoir. Delivery adapter is fitted with a 12/5 spherical joint for flexibility and a 0-4mm Chem-Vac™ Chem-Cap® valve (D) for purging of the receiving vessel. Top outer joint is a 24/40 while the uptake tube is a 24/40 inner joint. Delivery adapter has a 14/20 inner joint and is supplied with the complete apparatus along with a CG-150-02 S.S. Pinch Clamp.
