Embodiment Construction

[0088] In the following description, the expressions "upper" and "lower" relate to preferred orientations of the injector and the metering device in operation, wherein the injector and the metering device are each oriented vertically, the injector having its coding element and verification element on the upper end, On the other hand, the metering device has its receptacle with the detection device at the lower end. In this orientation, in particular when the syringe is inserted into the metering device, the syringe with its intake and delivery opening is arranged below.

[0089] 1 to 3 show a syringe 1 with a filling volume of 1.0 ml, which has a syringe barrel 2 and a syringe plunger 3 . The syringe barrel 2 is not all strictly cylindrical in geometry. The syringe barrel has an internally and externally cylindrical cylindrical section 4 which has a cylindrical piston active area 5 on the inside.

[0090] The lower end of the cylindrical section 4 is connected via a shoulder...

Abstract

Syringe having a syringe cylinder and a syringe piston for use with a metering device for metering liquids in the laboratory, having a holder for the syringe cylinder and an axially displaceable piston holder for the syringe piston, comprising: a code on the upper rim of the syringe cylinder having code elements in the form of elevations and depressions in seven code positions distributed uniformly in the circumferential direction in an identifying arrangement for the type of syringe; test elements in the form of further elevations and further depressions in seven test positions, each of which is arranged between two code positions on the upper rim of the syringe cylinder, wherein the code elements and the test elements have a total of six elevations; and a guide structure on the circumference of the syringe cylinder, which has a specific location in relation to the code elements and the test elements, in order to align the syringe with a further guide structure in the holder of the metering device, which has a specific location with respect to an annular sensing device for sensing the code, having sensing elements of the metering device distributed uniformly over the circumference, with each code element and with each test element on a sensing element.

Description

technical field [0001] The invention relates to a coded syringe for use with a metering device having detection means for detecting the code, and to a syringe system comprising a plurality of Syringes with different codes. Furthermore, the invention relates to a dosing device for use with a coded syringe, said dosing device having detection means for detecting the code. Furthermore, the invention relates to a dosing system comprising a syringe with a code and a dosing device with a detection device for detecting the code. Finally, the invention relates to a method for operating a dosing system comprising a syringe with a code and a dosing device with a detection device for detecting the code. Background technique [0002] Metering systems comprising syringes and metering devices are used for dosing liquids and are used especially in laboratories of biology, chemistry and medicine. A metering device configured as a dispenser makes it possible to dispense liquid from the sy...
