Distillation Labware
Glassware and replacement parts designed to carry out distillations in laboratory settings; includes condensers, distillation heads, receivers, etc. Products are available for various scales and for specialty distillations.
Distillation is a process used widely in the laboratory or in wider working environments for separating or purifying liquids or liquid mixtures based on the different boiling points of individual components.
Distillation Applications:
• Separation and purification of miscible liquid mixtures in organic chemistry
• Drying of solid residues and/or solvent removal
• Fractional distillation of liquids from polymers and petroleum products
• Removal of particulates or other solid contaminants
• As part of a water purification system for production of distilled water for laboratory use
• Specialist steam distillation-based applications such as Kjeldahl analysis of nitrogen and proteins in food, beverage, or environmental samples
What Types of Distillation Equipment Are Available?
Conventional distillation apparatus, typically comprising individual, jointed borosilicate glassware components assembled by the user (depending upon the application), using appropriate clamps, stands, and supports. Most conventional distillation assemblies combine a round-bottomed distilling flask to contain and heat the liquid(s) that require purification, fitted with a stoppered or jointed neck to which is attached a downward-sloping, inclined side-arm for connection to a condensing unit to cool the heated vapors back down to their liquid state. Heating mantles are the preferred heat source for improved temperature control. These conventional distillation units are also available supplied complete and ready-assembled for added convenience and ease of use.
Specialized automated distillation equipment, notably units designed for the determination of volatile acidity and alcoholic strength by volume in wines, musts, and alcoholic beverages, and units designed for Kjeldahl nitrogen or protein determinations.
Chemglass Life Sciences Adapter Only, Distribution, 24/40 Joint
Adapter replacement part for the CG1276 series of cow type design distillation receivers. 24/40 Joint. Adapter only.
Chemglass Life Sciences 500mL Solvent Distillation Still Head, Airfree, Schlenk
500mL Solvent Distillation Still Head, Airfree, Schlenk. Still head in 500mL capacity for use in re-purification of solvents under inert atmosphere. One-piece design of condenser and storage reservoir eliminates multiple connections usually associated with distillation setup. 0-4mm Chem-Vac™ Chem-Cap valves provide for grease-free, leakproof seals. Lower 3-way valve (C) allows for solvent return to flask, take-off or storage in graduated reservoir. Syringe access port (B) incorporates a 4mm PTFE stopcock with a 14/20 outer joint for use with CG-3022 septum stoppers permitting repeated syringe punctures or changes of the septum without breaching the integrity of the solvent. Valve (A) allows for isolation of the still from the inert gas source. Valve (D) permits evacuation and purging of the receiver flask. Uptake tube (F) is a 24/40 inner joint, while the takeoff connection (E) is a 14/20 inner joint. Design Suggested by Dr. Thomas Oberhauser.
Chemglass Life Sciences Hickman Still Head, Minum-Ware
Hickman Still Head, Minum-Ware. Unique design of the Hickman still makes it both the collection vessel and condenser for simple fractional distillations. The threaded side port permits easy removal of distillate via a syringe or Pasteur pipette. Side port has a 8-425 thread. Still has an upper threaded outer joint and lower inner joint, both 14/10. Supplied complete with open-top screw cap (MW-102-33) and Viton o-ring (MW-100-08) for 14/10 joint and PTFE faced septa (MW-104-01) and open-top screw cap (MW-102-11) for 8-425 sidearm.
Chemglass Life Sciences 100mL HW Pressure Vessel, Cylindrical, #15 Internal Thread, Complete, 38mm O.D. x 190mm Length, Bushing Size/15
100mL Heavy Wall Pressure Vessel, Cylindrical, #15 Internal Thread, Complete, 38mm O.D. x 190mm Length, Bushing Size/15. Heavy wall pressure vessels have an internal thread for use with PTFE bushings as pressure seals. The design allows hand tightening/loosening for easy access into the vessel. O-ring is positioned on the bushing above the thread for improved sealing. Supplied complete with vessel, PTFE bushing & Viton o-ring. Optional Perfluoro o-ring has the chemical resistance & service temperature range similar to Kalrez 4079. See CG-362, CG-364, and CG-366 for optional PTFE Bushings.IMPORTANT NOTICE: ALL CHEMGLASS PRESSURE VESSELS ARE TESTED AT 150 PSI, OR APPROX TWO AND ONE-HALF TIMES THEIR RECOMMENDED WORKING PRESSURE. HOWEVER, CHEMGLASS DOES NOT GUARANTEE THE VESSEL FROM BREAKING UNDER PRESSURE, DUE TO THE NATURE OF MATERIAL AND CONDITIONS BEYOND OUR CONTROL. CHEMGLASS RECOMMENDS THE USE OF SAFETY SHIELDS AND/OR OTHER SAFETY EQUIPMENT.
