Functional modules connect some of the most important components in a micro-fluidic system. The modules consist of mounting block and an integrated filer (F-P functional module) or, alternatively, mounting block, filter and a shut-off valve (F-P-V functional module); these components are combined with micro annual gear pumps (mzr® pumps).
Functional modules are characterized by direct fluid connections which ensure that the dead volume for the compact system is as low as possible. The high amount of integration reduces the installation space needed. The integrated wire mesh filter, which has a mesh size of 10 µm, protects the pump and the downstream fluidic micro-structure from contamination by the liquids to be pumped and the upstream system components. Changing the easily accessible filter is simple and can be carried out without dismantling the pump.
