Laboratory vacuum system MD 12C NT

high flow capacity

Overview

• Outstanding chemical resistance and high vapor tolerance
• High pumping speed even near ultimate vacuum reduces process time
• Very low vibration and low noise (50 dBA at 50 Hz)
• Good ultimate vacuum even with gas ballast open for condensate purge
• Inlet separator (AK) and exhaust condenser (EK) enable efficient solvent recovery and protection under rough conditions

Short description
The MD 12C NT +AK+EK chemistry vacuum system is designed for evacuation, evaporation and pumping of gases and vapors in chemical and pharmaceutical environments. The compact MD 12C NT pump delivers particularly high pumping speed and achieves a very good ultimate vacuum even with the gas ballast open, making it suitable for applications with high-boiling solvents. Materials and construction are selected for chemical compatibility to allow broad use in laboratory and production settings. The AK inlet separator protects the pump from particles and liquid droplets; the EK exhaust condenser provides compact, near‑100% solvent recovery for recycling and environmental protection.
