Double-Through Separating Chamber

The Double-Through Separating Chamber is a versatile, dual-compartment TLC development chamber designed for the simultaneous development of two thin-layer chromatography plates. Built from durable, high-quality borosilicate glass or chemically resistant polymer, this chamber enhances laboratory efficiency by allowing side-by-side comparison of samples or methods.

The chamber features two separate internal grooves or slots that securely hold two TLC plates—commonly up to 20×20 cm or 10×20 cm in size. Each compartment functions independently, permitting either the same or two different solvent systems to be used simultaneously. This feature makes it ideal for comparative chromatographic studies, solvent system evaluation, or parallel sample analysis.

A precision-sealed lid—either ground-glass or flat—ensures a tight seal, minimizing solvent evaporation while maintaining an evenly saturated internal atmosphere. This uniform saturation guarantees consistent development across both plates, resulting in sharp, reproducible separations.

The clear design of the Double-Through Separating Chamber allows users to monitor solvent front progression in both compartments, facilitating real-time observation and accurate timing for plate removal. Whether for pharmaceutical quality control, forensic testing, environmental screening, or food safety analysis, this chamber supports efficient and reliable dual-sample workflows.

In research and development settings, the double-through design saves time and solvents by enabling comparative experiments within the same device. Academic institutions also benefit, using the chamber to teach chromatography principles and demonstrate solvent effects in a single lab session.

Reusable and easy to clean, the Double-Through Separating Chamber is built for long-term use, providing exceptional value and performance. Its ability to handle simultaneous TLC development with either matched or varied solvent systems sets it apart as a highly practical and innovative tool for modern chromatographic analysis.
