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 Sublimator Complete, Minum-Ware
Sublimator Complete, Minum-Ware. Sublimator consisting of a MW-33 adapter and vertically adjustable condenser tube having an O.D. of 7mm. For use with all 14/10 jointed flasks and reaction vials. Supplied complete with nylon compression cap (CG-352-01) and Viton o-ring (CG-305-07).
Petroleum Analyzer Corporation Ferrule, Vespel, Reducer, 1/8 - 1/16
Ferrule 1/8"-1/16" Reducer Vespel
Chemglass Life Sciences Sublimation Apparatus, 50mL, Complete
Sublimation Apparatus, 50mL, Complete. Two-piece sublimer consisting of an upper water cooled condenser and lower flat bottom flask. Sublimate is collected on the inner wall of the condenser. The two components are assembled by a grease-free o-ring seal which permits the components to be gently separated for maximum product recovery. When condenser is inverted, the top vacuum connection serves as a funnel for convenient product removal. Complete apparatus consists of a condenser, flask, Viton o-ring and CG-150 Stainless Steel clamp.
Chemglass Life Sciences 125mL Solvent Distillation Still Head, Airfree, Schlenk
125mL Solvent Distillation Still Head, Airfree, Schlenk. Still head in 125mL 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.
