Embodiment Construction

[0047] The invention and specific embodiments thereof are explained in more detail below:

[0048] The device may include the following components: a compressed air device with pre-set pressure stabilized air (at least 3MPa), a driver head housing a pressure pulse generator connected to the air device, the driver head can be folded upwards and away from the container The curve is a static, non-operating state, the sealing portion and the management portion of the pressure pulse, the dispensing nozzle driven by the pressure pulse, the detection device for detecting the droplets, the waste container for capturing the released droplets.

[0049]The quantification device may consist of a dosing nozzle, in particular a conical container with a precisely manufactured capillary opening in the bottom. The openings are circular and preferably have a diameter of 60 μm. Liquids with suitable surface tension cannot flow through the openings under equilibrium pressure conditions due to ca...

Abstract

The present invention concerns the technical field of volumetric measurement and volumetric instruments and provides novel devices and methods for the determination of the volume of a fluid.

Description

technical field [0001] The present invention relates to the technical field of volumetric measurements and volumetric instruments and provides novel devices and methods for the determination of the volume of fluids. Background technique [0002] A trend in biotechnology and chemistry is to use smaller and smaller quantities of liquids to efficiently use expensive substances or to be able to perform as many tests as possible from an often limited sample size (volume). Other trends include automation and parallelization of experiments. Volumetric instruments should therefore deliver smaller and smaller volumes. In order to be able to accurately calibrate volumetric instruments, test methods must be able to produce reliable results within these volume ranges. [0003] Volumetric measurements are basic in chemical or biological laboratories. In modern micro-scale applications, such as in microbiology, genetics or tissue engineering, there is a high demand for dispensing small...
