µDispense Compact and smart dosing system
Beschreibung
The Micro Dispense Module µDispense ® is a compact system for the precise dosing and metering of liquids in the microliter to milliliter range. µDispense ® guarantees a process-safe liquid handling, with high precision and trueness. It reduces maintenance expenses due to its long service life. The size of a Micro Dispense Module corresponds to the half-height syringe pumps format. With the Cavro ® script language protocol and an extended command set, syringe pump programs can be processed. Due to the interface compatibility, syringe pumps can easily be replaced. The Micro Dispense Module is characterized by its modular design with optional modules, such as shiftable in- and outlet, optional pump size, filter and flow sensor. The core component is a micro annular gear pump, a robust and highly precise device with an extremely long service life and low pulsation. The quiet and rotatory operating micro annular gear pump allows dispensing smallest volumes of liquid on the one hand,...
