Legacy DEGASi® Semi-Prep

Discontinued old degasser model

Information below for reference only

When working with higher flow rates, up to 6 ml/min, we strongly recommend DEGASi® Semi-Prep degasser equipped with 925 µl degassing chambers.

These chambers can be used up to 10 ml/min but with a bit lower degassing efficiency.


  • Ultra-high degassing efficiency
  • Fits every system
  • Long life expectancy – 5+ years continuous (24/7) running capacity
  • Easy to prime
  • Extremely quiet
  • Closed loop vacuum control means constant vacuum (variable RPM)
  • ZHCR® patented control eliminates baseline fluctuations
  • Excellent chemical compatibility flow path
  • Biocompatible flow path
  • Continuous vacuum system monitoring to ensure optimum operational conditions are maintained
  • Advanced error and leak checking functions
  • 2-pin vacuum level validation output
  • CE & RoHS compliant
