Available in two versions: 0 to 2000 mbar, -700 to 1000 mbar.

The Cobalt is an autonomous pressure or vacuum controller based on the Elveflow Mk4 piezo technology.

  • Precise pressure or vacuum control: delivers a smooth flow with the highest accuracy
  • Intuitive user interface: built-in screen or Windows software
  • Integrated pressure or vacuum pump: no external source required
  • Quick Connect reservoir connection: plug and unplug your reservoirs in a second
  • Compact and standalone

Unique performance in a standalone system

The Elveflow Cobalt is available in two versions:

  • 0 to 2000 mbar (pressure control)
  • -700 to 1000 mbar (pressure & vacuum control)

When paired with an MFS flow sensor, the Cobalt generates a smooth flow with ultra-short settling times:

  • high stability (0 to 5 ml/min range): repeatability from 3.5 nl/min (MFS2) up to 1 µl/min (MFS5) in water
  • high accuracy: from 20 nl/min (MFS2) up to 10 µl/min (MFS5) in water
