Bartels Mikrotechnik Quickens Appetite for the Upcoming Micropump mp6
Presenting two new products, Bartels Mikrotechnik works in double activity in the run-up to the launch of the next generation of micropumps, scheduled for autumn 2008. The micropump variant mp5² and an improved version of the controller electronics are now available as the youngest members of the Bartels Mikrotechnik microfluidic product family.
New Pump as an Appetizer
Combining two pumps to function as one small power pack, the mp5² provides a foretaste of the upcoming mp6's benefits. This completely new generation of pumps will feature a double actuator inside a single polymer housing. Although still working with two actuators in separate housings, the mp5² already exhibits the most important advantage of the mp6: Double pressure.
When driven by the optimal signal, the piezo actuators of two serially combined mp5 pumps can handle back pressures of up to 500 mbar, still reaching a maximum flow rate of 5 ml/min. Compared with one mp5, an improved compression behavior leads to better self priming and higher bubble tolerance. Thus gas-liquid-mixtures can be transported easily with the mp5².
Optimized Controller for the New Generation
To fully exploit the new possibilities of the mp5² and mp6, Bartels Mikrotechnik has developed an optimized version of the pump controller mp-x. One of the main improvements is the novel driving signal SRS, that allows flow rates comparable to the ones possible with the common rectangular signal, but has two additional advantages: It reduces the pumping sound to a minimum and increases the long term stability of flow rate.
With connectors for one mp5, one mp5² or one mp6, the new controller is well equipped for the upcoming generation of micropumps. Due to a USB interface on the new mp-x, the pumps can now be controlled via the user's PC. Windows standard software Hyperterminal or applications as LabView allow tests with precisely programmed driving profiles. The adjustable parameters are amplitude (0-250 V, in increments of 0.5 V), frequency (0-300 Hertz) and signal form (sine, rectangular or SRS).
