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 Distilling Column, 14/20 Joint, 130mm, Vigreux
Distilling Column, 14/20 Joint, 130mm, 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 Bump Trap, 100mL, Self Washing, Rotary Evaporator, 24/40 Top Outer, 29/26 Lower Inner
Bump Trap, 100mL, Self Washing, Rotary Evaporator, 24/40 Top Outer, 29/26 Lower Inner. Trap is designed to eliminate hold up common to the round style of rotary evaporator traps. Tapered sidewalls permit continuous washing with condensed solvent while preventing vapor cooling points along the path of the condenser. The upper stem has 4 large holes flush with the lower end, allowing solvent vapor to flow freely and making this portion of the trap easy to clean. The increased volume of the trap prevents “bumping” and keeps solvent out of the vapor tube.
