Visit product website DATA SHEET 1000185431 | Standard | EU | en | 202105 | 07 Micro Dosing Unit for precise dosing in microlitre-range
- Diaphragm pump for high chemical resistance
- Dosing volume 5 µl/stroke up to 8 ml/min. in both directions
- Dosing accuracy < +/- 3,5 %
- Self priming
- Integrated electronics, easy to use Bürkert’s Micro Dosing Unit has been designed for precise dosing applica- tions in the microliter range. It combines high dosing accuracy and precision with excellent chemical inertness. The unit is comprised of three valves which can be opened simultaneously for flushing. Active inlet and outlet valves en- able the device to pump liquid in two directions. This feature can be used to mix fluids inside a tube or channel or to constantly keep them in motion. Rea- gents can be sucked back from the dispensing tip to prevent drying out after dosing. The integrated heating function heats up the valves and the medium, and the unit comes with dry running capabilities. Product variants described in the data sheet may differ from the product presentation and description. Type description Type 7615 © Christian Bürkert GmbH & Co. KG, Subject to alteration

F unction modes Note: Further information can be found in the operating instructions, see Type 7615 Different modes can be preselected via a rotary switch on the electronics:
- Impulse mode: An electrical power signal of min. ms (mode resp. 120 ms (mode length creates a dosing of µl at a time. Higher volumes (multiples of μl) can be dosed by repeating the signal.
- Frequency mode: The unit runs with a predefined frequency. Different frequencies can be selected (see following description). The standard setting is 5 Hz. Function modes Description Rotary switch to select mode Impulse mode 120 ms Frequency mode 40 Hz Frequency mode 25 Hz Frequency mode 10 Hz Frequency mode 5 Hz (Standard) Service mode 5 Hz (pump stops after 100 cycles) Quick impulse mode 50 ms
