Bartels mp6 Micropumps

Bartels mp6 series micropumps are a revolution in the field of microfluidics. Capable of transporting a very small quantity of liquid or gas, the micropumps of the mp6 series are characterised by the combination of 2 piezo actuators in a ultra-compact unit and very light weight.

Available in different versions (mp6-liq, mp6-gas, mp6-gas+), you are sure to find the right mp6 micropump for your application.

General

With an ultra-simple design and construction, these mp6 micropumps can perform a wide range of tasks, including moving diagnostic samples through a microfluidic device, dosing lubricants, supplying sensors with a gas sample, mixing solutions, and much more.

• Wide range of mp6 micropumps for liquids & gases (mp6-liq), and gases (mp6-gas, mp6-gas+)
• Flow rates from 8 µL/min up to >10 mL/min
  
• Ultra-compact (30 x 15 x 3.8 mm) and light (2 g only)
• Good temperature resistance
• Almost entirely made of plastic, various wetted materials for a wide chemical compatibility

Note: The mp6-hyb is now called mp6-liq, the old version of the mp6-liq is now discontinued.

Principle

Bartels micropumps are based on a piezoelectric diaphragm in combination with passive check valves. When applying voltage, a piezo ceramic mounted on a coated brass membrane is deformed, and the medium is being displaced out of the pump chamber below.

The flow rate of the pumps shows a linear dependency on the back pressure. At 0 mbar back pressure the maximum pump rate can be achieved and at the maximum back pressure the flow rate is decreased to 0 mL/min. The relation of pressure and flow rate is linear.

The typical lifetime of the pumps is 5000 h.

We recommend the mp6-liq for most applications, as it is the most versatile and cost-effective micropump.

mp6-liq: for liquids and gases, flow range 8-12000 µL/min

mp6-gas, mp6-gas+: for gases, flow range 12000-40000 µL/min

Flow rates & back pressures

The following table shows typical fluidic values at standard driving and environment parameters. These values were measured in a defined environment in a defined fluidic system at 25°C, 1 bar atmospheric pressure, humidity: 70%. For driving the pumps, the mp-Labtronix was used at 250Vpp/100Hz/SRS for water and 250Vpp/300Hz/SRS for gas. Values can vary under application conditions.
