Embodiment Construction

[0057] The following note applies to the following description: If reference signs are assigned in the figures for the sake of clarity, but are not mentioned in the directly relevant descriptive part, then for the explanation of the reference signs refer to the preceding or following descriptive part . Conversely, in order to avoid excessive drawing effort, reference numbers which are hardly relevant for direct understanding are not shown in all figures. For this, reference is made in each case to the other figures.

[0058] figure 1 The weighing device of the first shown embodiment comprises an electronic balance 10 detachably mounted on a robot arm 20 depicted only symbolically by a box. For controlling the robotic arm 20 an electronic controller 100 is provided. With the aid of the robot arm 20 , the balance 10 can be moved in three spatial directions within the reach of the robot arm.

[0059] On the balance 10, the dosing head, indicated generally at 30, is mounted on...

Abstract

The invention relates to a metering apparatus comprising a scales (10), on which a metering head (30) is arranged such that the scales (10) measure the weight of the metering head, and a metering tool (40) fastened to the metering head (30) to receive and dispense a substance. The metering tool (40) is designed as a glass tube (42) comprising a glass stamp (44) arranged for sliding adjustment in a sealed manner. The metering head (30) is provided with a first gripping tool (36) for clamping the glass tube (42), and with a second gripping tool (38) for clamping the glass stamp (44). The metering head (30) further comprises a lifting and lowering device (34), by means of which the second gripping tool (38) can be raised and lowered in relation to the first gripping tool (36) and thus the glass stamp (44) in the glass tube (42) of the metering tool (40). Control electronics (100) control the scales (10) and the lifting and lowering device (34), as well as the first and the second gripping tool (36, 38).

Description

technical field [0001] The invention relates to a device for metering substances according to the preamble of independent claim 1 . The invention also relates to a metrology method using the device and a metrology tool used in the device. Background technique [0002] Substance libraries or compound libraries are at the heart of every chemical business, especially pharmaceutical companies. Many compounds, often subject to decades-long synthetic activity, are stored in such libraries, the origin of many activity screens. The substances or compounds that are put into storage are often very valuable, difficult to synthesize, expensive to purchase or expensive to extract, and such substances generally only exist in very small quantities worldwide. [0003] Pharmaceutical companies often stock more than a million substances in their substance libraries and manage them with their own substance management teams tasked with delivering very small quantities from the libraries down ...
