Premium Pressure and Vacuum Control
Choose between two Cobalt versions; both allow either gas or flow control when paired with a flow sensor.
- 0 to 2000 mbar positive pressure control
- -700 to 1000 mbar dual vacuum & pressure control
The Cobalt technology improved microfluidic instrument performance and made ease of utilization a reality. This autonomous microfluidic pump was engineered based on the OB1 MK4 controller – our Elveflow® best-seller – using the Piezoelectric-based pressure regulation.
Unique Performances Compared to Syringe or Peristaltic Pumps
The Elveflow® Cobalt autonomous microfluidic pump offers superior fluidic performances compared to microfluidic syringe or peristaltic pumps. It generates smooth flow with the highest accuracy since it does not use a mechanical piece to produce pressure.
When paired with the MFS flow sensor from our product line, Cobalt generates powerful flow control with:
- high stability on a 0 to 5ml/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
For more details, please refer to the MFS series specifications.
Autonomous & Standalone Instrument
No Need for Gas/Vacuum Supply:
Cobalt is the ideal benchtop companion. It is equipped with a pressure (and vacuum) source so it does not require an external compressor or laboratory gas supply. Its design minimizes vibrations and sound volume.
Embedded User Interface:
Cobalt’s intuitive firmware can be fully controlled without the need of external software. Its user-friendly interface contains a knob button for easy setting modifications.
