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.

Distilling Head, Short Path, Vigreux Indents, 10/18 Thermometer Joint, 14/20 Lower Inner Joint, Approx. 110mm Width x 110mm Height. Designed for use with small quantities where hold up between the flask and receiver must be kept to a minimum. The thermometer bulb and stem serve as column packing. Upper hose connections are for cooling lines while the lower connection is for vacuum. Available with Vigreux indentations to improve efficiency. NOTE: The 14/20 size accepts a 1” immersion 7/12 or 10/18 thermometer, while the 24/40 and 29/42 sizes accepts a 2” immersion, 10/30 thermometer.
Chemglass Life Sciences Condenser, 45/50 Joint, Reflux, 315 x 100mm
Condenser, 45/50 Joint, Reflux, 315 x 100mm. Compact high efficiency reflux condenser employs a double wall thimble shape bulb sealed into the outer jacket. Serrated hose connections for water connection extend through the outer bulb and have an O.D. of 10mm at the middle serration. While the overall height of this condenser is only 210-215mm, it has the efficiency of a standard 400mm Liebig or West condenser.
Chemglass Life Sciences 0-8mm Chem-Vac Chem-Cap Valve
0-8mm Chem-Vac Chem-Cap Valve. CHEM-VAC CHEM-CAP valve has a single sidearm sealed at a 90 angle to the barrel. This inexpensive configuration allows for the lower portion of the barrel to be sealed directly to the apparatus being constructed, making for more compact, stronger assemblies. See CG-961 for replacement CHEM-CAP plug and CG-902 for glass portion only.
Chemglass Life Sciences Distilling Receiver, 20mL, Moisture Test, Barrett, Jacketed, 24/40 Joint Size, 2mm PTFE Stopcock, Approx. 325mm Height x 105mm Width
Distilling Receiver, 20mL, Moisture Test, Barrett, Jacketed, 24/40 Joint Size, 2mm PTFE Stopcock, Approx. 325mm Height x 105mm Width. Similar to CG-1261 but with the uptake tube vacuum jacketed to improve distillation performance. The jacket eliminates the possibility of condensation or recrystallization of distillate in the sidearm. The 5ml has subdivisions of 0.20ml; 10ml has subdivisions of 0.1ml; the 20ml has subdivisions of 0.2 from 0 to 3ml and 0.5 from 3 to 20mL. Available with glass or PTFE stopcocks.
Chemglass Life Sciences Distilling Column, 24/40 Joint, 150mm, Vigreux
Distilling Column, 24/40 Joint, 150mm, Vigreux. Vigreux style column with indentations that run the entire length of the column for improved vapor-liquid contact. Column length refers to the effective length, measured from the lowest to highest indent in the column. Column has a top outer and lower inner standard taper joint.
Chemglass Life Sciences Distillation Head, Vigruex, Jacketed, 10/30 Thermometer Joint, 24/40 Joint Size, 200mm Column Length, Approx. 325mm Height x 350mm Width
Distillation Head, Vigruex, Jacketed, 10/30 Thermometer Joint, 24/40 Joint Size, 200mm Column Length, Approx. 325mm Height x 350mm Width.
