Digestion Systems

Distillation systems manually or automatically purify liquids through heating to evaporate the volatile components. Designed to follow the physical separation with a cooling cycle, the materials are efficiently extracted, leaving a condensed substance with a higher purity. Providing more control in sample preparations, the stills facilitate more consistent testing results and eliminate hazards common in traditional preparative methods. The benchtop distillation systems come with one or multiple sample places when higher batch yields are needed.
