Definitions
- the invention relates to a hand-dispensing device, in particular a pipette, with a dispensing mechanism for dispensing egg ⁇ nes defined fluid volume, hereinafter called dispensing volume, in particular a liquid volume, with a Volumenverstellmechanismus for adjusting the dispensing volume, with a volume display for displaying a set dispensing volume and with a control to operate the volume adjustment mechanism.
- Handdosiervoriquesen are already known in various embodiments of the prior art.
- the hand-dosing devices are calibrated and adjusted after their manufacture.
- the manual dosing devices should be calibrated several times a year and adjusted if necessary.
- the manual dosing devices must be adjusted. Some Handdosiervoriquesen an adjustment by the end user is not provided. In other manual dosing devices, it is possible to adjust the respective hand dosing device with a special tool. Other Handdosiervoruzeen can be adjusted without tools.
- a manual dosing device which is used in particular with pipettes having a fixed discharge volume
- the volume of fluid to be dispensed is adjusted to a defined desired value.
- a gravimetric calibration of the manual dosing takes place. If too great a deviation of the gravimetrically determined actual value from the preset nominal value is detected, the dispensing mechanism of the manual dosing devices is adapted accordingly to match the actual value with the desired value. For this example, a piston stroke of a piston of the dispensing mechanism can be changed. Calculation formulas can be used to determine the piston stroke change required for the adjustment, which is usually carried out by means of a screw or rotary movement on elements of the delivery mechanism or of the volume adjustment mechanism. However, this is associated with a certain effort. This adjustment procedure is used in many variable delivery volume handheld dosing devices.
- the volume display is brought into accordance with the actual dispensed fluid volume.
- the dispensing volume is initially set to a defined target value. Then it is calibrated and an actual value is determined. Now, the value displayed on the volume display is set to the actual measured value. An adjustment of the dispensing mechanism by the volume adjustment mechanism does not take place here.
- the object of the invention is therefore to provide a Handdosiervorraum of the aforementioned type, which offers the user the option to perform both one and the other type of adjustment.
- a manual dosing device of the type defined is proposed with the means and features of claim 1.
- the control comprises an associated with the volume display adostellmechanismus Volumenverstellelement, wherein the aspiringverstellelement and the Volumenverstellelement connected in the normal use position of the hand metering device via a releasable coupling are, so that a volume adjustment leads to a corresponding adjustment of the volume display and vice versa, and wherein the aspiringverstellelement and the Volumenverstellelement are independently adjustable with the clutch disengaged for adjusting the hand meter.
- the delivered fluid volume can then be determined in turn in a calibration step and the actual value of the delivered fluid volume can be determined. Subsequently, with the dispensing mechanism and the volume adjusting mechanism unchanged, the value for the dispensing volume indicated on the volume display is adjusted with the help of the dispenser adjustable independently of the volume adjusting element, and the displayed value is then matched with the ascertained actual value.
- the manual dosing device has a housing in which at least the dispensing mechanism and the volume adjustment mechanism are arranged.
- the volume adjustment element is also set up for actuating the dispensing mechanism.
- the volume adjustment can be assigned a dual function.
- an actuation of the Volumenverstellmechanismus using the Volumenverstellelements is possible.
- the Volumenverstellelement can also be used to actuate and trigger the dispensing mechanism of Handdosiervorraum.

- a transmission is interposed between the ippoverstellelement and the volume display, in particular between the ippoverstellelement and a mechanical counter volume indicator. It may be advantageous in this case if the transmission has a transmission ratio which is less than 1, that is, for example, one revolution of the essorverstellelements in ten revolutions of a connected to an output of the transmission counter wheel can be translated.
