ELVEFLOW Autonomous Microfluidic Pump Cobalt

Buy ELVEFLOW products from MSE Supplies at the best value.

Product Description

Autonomous Pressure & Flow Control Unit

Pressure range = 0/2000 mbar

All necessary fittings & tubing are available in the Kit Fitting Starter Pack COBALT

COBALT software included. Important note: pressure source is integrated.

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.
