Vacuum Degasser for analytical HPLC

HPLC Vacuum Degaser analytical

5-year guarantee on the high-performance membrane!

Our new HPLC Online Degassers offer the user highest
degassing potential.

Gases are removed from the solvents by applying vacuum via a semi-permeable membrane. Owing to the excellent gas permeability of the highly efficient Teflon-AF® material, the usual internal volume can be reduced. This considerably reduces the time required for stabilisation following a change in solvent.

The vacuum pump of this degasser operates in either constant or hysteretic mode, i.e. the pump switches on or
off at a defined reduced pressure.

The innovative, high-performance membrane, produced exclusively from a special Teflon material, provides a particularly service-friendly, continuous-flow degassing system. ERC offers an extended guarantee of 5 years on
this special membrane.

Performance characteristics

  • innovative membrane technology

  • highly efficient Teflon-AF® capillaries

  • 2 operation modes, constant or hysteretic mode

  • 2-channel or 4-channel version, for use in parallel or in series, metal-free

Function principle

The solvents each flow through a short Teflon-AF® capillary. Each capillary is in a separate chamber, in which a vacuum is produced by means of a vacuum pump. Any gases present in the eluents are thus removed through a semi-permeable membrane. By using highly efficient Teflon-AF® material, very short capillaries with a small dead volume (<500 µl) can be used.
