SDU Standard Distillation Unit

SDU Standard Distillation Unit

The SDU – Standard Distillation Unit is a modular industrial glass distillation system engineered for precise separation, purification, and recovery of liquid mixtures using controlled boiling and condensation principles.

Manufactured from scientific-grade Borosilicate Glass 3.3, the SDU is designed for chemical laboratories, pilot plants, R&D facilities, and small-scale production units, where process visibility, chemical compatibility, and operational safety are critical.

This unit supports atmospheric as well as vacuum distillation, making it suitable for heat-sensitive materials, solvent purification, essential oils, intermediates, and specialty chemicals.

Construction & Design Details

• All-glass contact parts ensure zero contamination
• Ground glass joints provide leak-proof and secure connections
• Uniform wall thickness reduces thermal stress
• Vertical configuration ensures efficient vapor-liquid separation
• Modular layout allows easy dismantling and cleaning

Each unit is assembled to maintain optimal vapor flow, efficient condensation, and stable liquid collection.

Working Principle

• The feed material is charged into the distillation flask
• Controlled heating causes the liquid to vaporize at its boiling point
• Vapors pass through the distillation head / column
• Vapors are cooled inside the condenser
• Condensed liquid is collected in the receiver flask
• Residual non-volatile components remain in the boiling vessel

The process ensures clean separation based on boiling point differences with excellent repeatability.

Main Components Included

•         Boiling / Distillation Flask
•         Distillation Head
•         Liebig / Coil Condenser
•         Vacuum Adapter
