The new micro dosing unit Type 7615 is a high-precision diaphragm pump for exact dosing in the microliter range. Comprised of three valves, the dosing unit doses 5 µL in one stroke with an accuracy of ±2%. The maximum flowrate is 8 mL in both directions. The flowrate can be changed by the frequency, operating at 5 Hz standard, with options for 10, 25 and 40 Hz. The micro dosing unit is an alternative to syringe pumps, for applications in analytical laboratories, water analysis and the dosing of lubricants. — Bürkert GmbH & Co. KG, Ingelfingen, Germany
