FDG-L Series Laboratory Fractional Distillation Equipment

Product Overview

The FDG-L Series is a versatile, high-performance lab fractional distillation system designed for laboratory R&D, process development, and small-batch purification.
With capacities ranging from 1 L to 20 L, this fractional distillation equipment offers high separation efficiency, excellent chemical compatibility, and operational flexibility. The system is suitable for applications including pharmaceuticals, essential oils, biofuels, and high-purity chemical synthesis.

Capacity

1 - 20 L

Mantle Heating

Fractionating Columns

Up to 380°C

30/35/40mm × 1m
[custom lengths available]

Modular Fractionating Column: Standard fractionating columns are available in 30/35/40 mm diameters with a 1 m height, while customized column lengths can be supplied for specific separation requirements.
Diverse Packing Options: Compatible with θ-rings, glass springs, Raschig rings, and structured packings for high-purity separation.
Flexible Distillation Setup: Supports both atmospheric and vacuum distillation (≤50Pa), suitable for heat-sensitive materials (e.g., vitamins, essential oils).
High Chemical Compatibility: Constructed with borosilicate glass and PTFE, resistant to acids, alkalis, and organic solvents.
Visual Process Monitoring: The transparent borosilicate glass design allows real-time observation of vapor-liquid flow and packing conditions during the fractional distillation process.
Easy Cleaning: Smooth surfaces minimize residue and cross-contamination risks.
