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 Distillation Head, 250mL, Solvent, Modified, 24/40 Inner Joint On Take-Off
Distillation Head, 250mL, Solvent, Modified, 24/40 Inner Joint On Take-Off. Designed to maintain distilled solvents in an inert atmosphere. Top of main vapor tube is open and an additional vapor tube has been added to decrease risk of pressure buildup. Upper sampling port has a 4mm PTFE stopcock with a 14/20 outer joint for use with CG-3022 septa. Lower drain is centered to allow total drainage of storage head. Double oblique 2mm bore PTFE stopcock on the 250 through 1000mL sizes allows for removal of distilled solvent or return to flask. The 250mL size has a 4mm double oblique stopcock. Both the uptake tube and top outer joints are 24/40, while the take-off tube is supplied with a 24/40 inner joint.**Design suggested by Dr. A.K. Saksena, Schering Plough Research Institute, Kenilworth NJ.
Chemglass Life Sciences Distilling Receiver, 15mL, 14/20, Complete
Distilling Receiver, 15mL, 14/20, Complete. Cow type design has three receivers 45º apart. Condensers with lower drip tip inner joints will protrude into the spherical section, permitting the distillate to fall directly into the receiving flasks. Distribution adapter has a serrated connection for attachment to vacuum source. Complete item supplied with distribution adapter, three flasks of the listed size and six stainless steel springs.

Ace Glass, Inc. DISTILLING APPARATUS COMP DISTILLING APPARATUS COMP
A compact fractionation unit for distilling small quantities in a vacuum, and for ordinary separation. Column is vacuum jacketed. The indents are positioned to cause the vapor to follow a spiral path. Approximately three theoretical plates at 60mL/hr. hold up to 1.2mL operating, 0.5mL static. Receiver capacity is 15mL. By use of the three-way stopcocks, a manifold arrangement is achieved, making it possible to remove receivers without disturbing the equilibrium of the system. 10/30 thermometer joints are for 25 mm immersion thermometers.
Ace Glass, Inc. 14/20 130mm distillation column
14/20 130mm long Vigreux distillation column. Length in millimeters refers to the effective length as measured from the lowest to the highest indent of the column.
