Category: Laboratory Vacuum System

Chemical-resistant laboratory vacuum systems, available in two- and three-stage configurations, feature pump models with 2 to 8 heads. These systems offer flow rates ranging from 1 m³/h (16.7 l/min) to 9.1 m³/h (151.7 l/min) at 50 Hz, delivering ultimate pressure levels from <8 Torr to <2 Torr.

Constructed with high-quality, chemical-resistant materials, including clear plastic-coated glassware, all wetted parts enable the pumping of solvent and acid vapors.

Additional features such as energy-saving exhaust vapor condensers and inlet separators safeguard the pump from liquid and particle ingestion.

The systems can be equipped with digital (ecoflex) vacuum controllers, allowing precise adjustment of vacuum levels for automatic, efficient, and reproducible processes. For applications requiring constant ultimate vacuum pressure, unregulated models are available.

Utilizing a hysteresis-free control method, these controllers dynamically adjust pump speed to maintain user-defined vacuum levels, ensuring stability despite changes in process requirements. This control method is particularly beneficial in evaporation processes, enhancing evaporation rates by up to 40% while minimizing sample bumping and foaming.
