Distillation

ABOUT DISTILLATION
  • Distillation is the process of separating the compounds of a solution according to their boiling points. Short path distillation uses a very small condenser and low pressure to isolate desired compounds. The compounds are collected in recovery flasks.
HOW UNITED (PRODUCTS) CAN HELP
  • Components are pre-selected for compatibility and offered as kits (Short Path Distillation Kits)
  • Heating and stirring equipment is available in a variety of capacities and configurations (Heating Mantles)
  • All glass components are made of high-quality borosilicate 3.3 glass (Condensers, Flasks, Distillation Head)
SHORT PATH DISTILLATION KIT, 250ML

This kit contains essential components for short path distillation. All glass parts are manufactured from high quality 3.3 borosilicate glass.

Short Path Distillation Head with 24/40 flask joints and 10/30 thermometer port features a condenser coil and three ¼” hose nozzles, two for condenser and one for vacuum.

The cow-type Distillation Receiver has one 24/40 outer joint and three 24/40 inner joints that can be used to attach up to three (included) 50ml Single Neck round bottom flasks.

The 250ml round bottom 2-Neck flask includes 24/40 outer joints to accept the Distillation Head and the Rubber Inlet Adapter. The Rubber Inlet Adapter holds the tapered Glass Inlet Tube.

The Thermometer, with a range of -10°to 50° C and filled with a petroleumbased solution with red dye, connects to the Distillation Head through the 10/30 port.

Plastic Clamps (six included in the kit), size 24, are used to secure glassware connections.

Penny Head Glass Stoppers (three included in the kit) are used to cap the 50ml Single Neck round bottom flasks after distillate is collected.

HEATING MANTLES WITH STIRRER

HMS1500 series Mantles feature stirring capability (50 – 750 RPM). Heating and stirring functions are independently controlled by 2 separate knobs. Each unit is supplied with a magnetic stir bar.

Mantles with stirrer feature polyurethane coated aluminum exteriors and a high quality knitted mantle with glass fiber underlay for uniform distribution of heat. Maximum operating temperature is 400°C. Mantles can be used in a wide range of ambient temperatures, from about 45°F to 100°F, and relative humidity up to 80%. The units are not waterproof, and are rated as IP code 10 equipment.

Power (from 0 – 100%) and stir speed (50 – 750 RPM) are controlled from 2 separate knobs that are built-into the unit. No need for a separate external control unit! Mantles are designed to securely hold flasks so that the top half of the flask is easily visible during operation. Elements can be replaced easily. An outlet tube is builtin for draining any spilled liquids. A 4-foot long grounded cord is included. Each unit features a fuse that can be easily replaced.

Heating mantles are used with a boiling flask and condenser to extract desired chemicals
