Rotary evaporator vacuum system MD 4C NT +AK SYNCHRO+EK

laboratorymulti-stage

Overview

• Designed for outstanding chemical resistance and high vapor tolerance
• High pumping performance even close to ultimate vacuum
• Good ultimate vacuum with gas ballast for solvent handling
• Simultaneous operation of two independent vacuum lines with check valves to prevent cross-interference
• Efficient solvent recovery for improved environmental performance

Product description
The MD 4C NT +AK SYNCHRO+EK chemistry vacuum system enables two vacuum processes to run in parallel from a single pump. Typical applications include rotary evaporators, vacuum concentrators and vacuum drying ovens for high-boiling solvents. Each vacuum port is fitted with a manual valve to control effective flow at that port. The MD 4C NT pump provides sufficient pumping speed for parallel operation of two demanding applications. The inlet separator (AK), made of glass with a protective coating, traps particles and liquid droplets. The outlet waste-vapor condenser (EK) is compact and highly efficient, enabling near-100% solvent recovery for reuse and reduced emissions. The unit is delivered ready for use with user manual.
