Apparatus and method for preparing solutions and/or dilutions in the laboratory
First Claim
1. Apparatus for preparing a solution of a solid with a liquid and/or a dilution of a liquid with another liquid, comprising:
- a balance that has a weighing pan, a display- and operating unit, a processor, a storage memory, and a data interface; and
at least one electronic dosage delivery device for liquids, the device being equipped with a microprocessor, a memory unit, and a data interface, wherein a communication can be established between the data interface of the balance and the data interface of the at least one electronic dosage delivery device, wherein the electronic dosage delivery device has an identifier element that signals when the electronic dosage delivery device has been selected, and wherein a program is executable in the balance for preparing a solution of a solid with a liquid and/or a dilution of a liquid in another liquid, said program being configured for performing calculations in the processor of the balance based on instructions input by an attendant, also based on substance data stored in the memory of the balance and in certain cases based on weighing results, said program being further configured for selecting a dosage delivery device from an available selection and setting the dosage delivery device for the liquid volume that is to be taken in and/or dispensed.

Abstract
A device is disclosed for preparing a solution of a solid with a liquid and/or a dilution of a liquid with another liquid includes a balance with a weighing pan, a display- and operating unit, a processor, a storage memory, and a data interface. The device includes at least one electronic dosage delivery device for liquids, in particular an electronic pipette, with a microprocessor, a memory unit, and a data interface, so that a communication can be established between the respective data interfaces of the balance and the at least one electronic dosage delivery device. An identifier element signals when the electronic dosage delivery device has been selected. A program is configured to perform calculations in the processor of the balance based on instructions given by the attendant, based on substance data stored in the memory of the balance and in certain cases based on weighing results. The program can select a dosage delivery device and set the selected dosage delivery device for the liquid volume that is to be taken in and/or dispensed.

10. Method for preparing a solution of a solid with a liquid and/or a dilution of a liquid with another liquid, wherein the method includes:
connecting a balance that has a display- and operating unit, a processor, a storage memory, and a data interface with at least one electronic dosage delivery device for liquids, the device being equipped with a microprocessor, a memory unit, a data interface, and an identifier element, wherein the balance and the at least one electronic dosage delivery device can communicate with each other through their respective data interfaces, and wherein a program in the processor of the balance;
performs calculations based on instructions given by the attendant, also based on substance data stored in the memory of the balance and in certain cases based on weighing results;
wherein said program selects a dosage delivery device from an available selection, sets the dosage delivery device for the liquid volume that is to be taken in and/or dispensed; and
activates the identifier element of a selected electronic dosage delivery device. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 22, 26)
