The invention relates to a laboratory instrument for working on laboratory samples, and a network instrument insertable inside a working chamber of the laboratory instrument. The laboratory instrument comprises a working chamber for housing the laboratory sam-ples, a network interface apparatus for providing a network connection capable of ex-changing data for the at least one network instrument, when the same is arranged and installed in an installed position inside the working chamber, the network interface appa-ratus comprising a communication apparatus being arranged outside the working cham-ber and providing the network connection, and a connector apparatus including at least one first connector for connecting with the network instrument, the at least one first con-nector being arranged facing the inside of the working chamber and being connected with the communication apparatus for allowing the data exchange.

A single-channel lower part for a pipette includes a housing lower part defining an interior space with an opening and a housing floor, an attachment for mounting a pipette tip, a through-channel extending from the lower end of the attachment into the interior space, and a spring space. The spring space includes a radially inwardly protruding limit with a through-opening. A plunger actuator is at least partially positioned in the spring space and configured to displace a plunger in a cylinder and align with the through-opening. A spring support is connected to the plunger actuator above the limit and protrudes radially outward from the plunger actuator. A helical spring is positioned in the spring space and supported by the limit and the plunger actuator extends through the helical spring. A first guide is structured to guide the plunger actuator in the axial direction of the housing lower part.

The invention relates to a plunger rod ( 10 ) for a liquid transfer device ( 100 ), the plunger rod ( 10 ) being of two- or multipart construction. The plunger rod ( 10 ) has a first plunger rod component ( 12 ), in operative connection with an actuating device ( 110 ) of the liquid transfer device ( 100 ), and a second plunger rod component ( 14 ). The plunger rod ( 10 ) comprises a sealing seat ( 16 ) for receiving a sealing element ( 18 ) for the plunger rod ( 10 ), wherein a parting line ( 20 ) between the first plunger rod component ( 12 ) and the second plunger rod component ( 14 ) is configured so the sealing seat ( 16 ) is free of parting line flash ( 22 ). The invention includes a method for producing a plunger rod ( 10 ) and a liquid transfer device ( 100 ), in particular a pipette ( 102, 104, 106 ) and/or a multichannel bottom part ( 108 ) for a pipette ( 102, 104 ), with such a plunger rod ( 10 ).

The invention relates to a pipetting device with a touch screen and a system comprising said pipetting device. The operating concept of this pipetting device provides that values of pipetting parameters can be set by the user on at least one input screen page, that actuation of the actuating element leads to the display of an output screen page and to the start of a pipetting operation defined according to the pipetting parameters, and that touching a separate input field of the output screen page leads back to an input screen page.

The invention relates to laboratory shakers for shaking laboratory samples stored in sample vessels in a chamber which comprises an pull-out mechanism which is extendable through a chamber opening for extending a sample platform storing the sample vessels in the extension direction A, which is shakable in a retracted position P 1 and which preferably comprises a securing mechanism for securing the position P 1, with a pivotable handle which is locked in a secured position S 1 and whose unlocking and a pivoting movement beginning in the pull-out direction A releases the securing effected by the securing mechanism.

The invention relates to a fill-level measuring device for a laboratory cabinet device, for measuring a fill-level in a liquid container in the interior of the laboratory cabinet device, which detects the fill-level by comparing the measurement of two NTC temperature sensors, the first of which is arranged in the air of the interior and the second in the liquid of the liquid container.

The invention relates to a laboratory instrument comprising a network interface apparatus ( 6 ), which is configured to provide, in the inserted position of the insertable instrument, a data connection between at least two network instruments of a laboratory instrument network ( 100 ), which network instruments are taken from the group of network instruments including at least a first control apparatus ( 4 ) of the laboratory instrument and the at least one insertable instrument ( 20; 30 ). The invention further relates to a laboratory instrument network including the laboratory instrument and a method for working on laboratory samples using the laboratory instrument network.

The invention relates to a system for logging a sequence of pipetting operations that are components of a pipetting method used in a laboratory experiment, the system implementing an interruption of a method recording and the possibility of its continuation. The invention also relates to a method of using the system.

Provided is a handheld fluid transfer apparatus, more particularly a pipette or repeater pipette, and a laboratory system comprising the handheld fluid transfer apparatus, which comprises: a control apparatus, which comprises a data processor capable to execute a control program for controlling at least one electronically controllable function of the handheld fluid transfer apparatus using input data, a user interface device for receiving a user input, the user interface device comprising a motion sensor device for measuring motion data of the handheld fluid transfer apparatus and for providing at least one motion data sequence, which contains subsequently measured motion data, a motion data memory for storing the at least one motion data sequence, an evaluation device being configured to determine the input data in dependence on the evaluation of the at least one motion data sequence. A method is provided for operating the fluid transfer apparatus or the laboratory system.

The invention relates to a pipetting device with a touch screen and a system comprising said pipetting device. The operating concept of this pipetting device provides that values of pipetting parameters can be set by a user on at least one input screen page, that actuation of the actuating element leads to the display of an output screen page and to the start of a pipetting operation defined according to the pipetting parameters, and that touching a separate input field of the output screen page leads back to an input screen page.
