Abstract: A gripper comprising an actuator and two fingers mounted parallel at a distance from each other on the actuator for movement perpendicularly to a longitudinal axis of the fingers, the fingers having a longitudinal body attached at one end to the actuator. The fingers having two longitudinal claws at the end opposite to the end attached to the actuator, the claws being spaced apart so that there is an elongated gap between the claws. At least one of the fingers having a groove for accommodating an optical fiber which extends partially into the elongated gap.

Abstract: According to an example aspect of the present invention, there is provided a gripper comprising an actuator and two fingers mounted parallel at a distance from each other on the actuator for movement perpendicularly to a longitudinal axis of the fingers, the fingers comprising a longitudinal body, means for attaching the body to the actuator and two longitudinal claws at the end opposite to the means of attachment, the claws being spaced apart so that there is an elongate gap between the claws.

Abstract: A novel solution is proposed for processing a test tube transported on a test tube carrier by a conveyor so that spilling of the liquid in the test tube is reduced or even prevented, particularly an arrangement for sequencing and guiding travel of test tube carriers transported on at least one conveyor. The arrangement includes at least one rotatable deviator positioned to intersect the at least one conveyor. The deviator includes a horizontal deviator plate including at least one grip for receiving a test tube carrier. One contact surface is positioned vertically at a distance from the deviator plate and aligned with the grip. The contact surface is formed to contact the test tube carrier at a distance from the contact level of the grip and the carrier.

Abstract: A chemical analyzer, a method for sample-based analysis, a device for handling cuvette assemblies including a rotatable incubator with at least one curved opening for receiving a new cuvette assembly, an analyzer arranged around the incubator for analyzing contents of the new cuvette assembly, and a loading device adapted to carry the new cuvette assembly while initially being aligned in a straight manner before being loaded. The loading device includes a feed funnel having a first end for receiving the new cuvette assembly initially aligned in the straight manner into the feed funnel, and a second end for feeding the new cuvette assembly into the at least one curved opening, the second end having a curvature which corresponds to the curvature of the curved opening, the second end for bending the initially straight new cuvette assembly and fitting the new cuvette assembly into the at least one curved opening.

Abstract: With the aid of the invention, a chemical analyser, a method for sample-based analysis, a device for handling cuvettes, and a loading method are provided. The chemical analyser (1) according to the invention comprises a rotatable incubator (20), in which there are openings (21) for receiving cuvettes (70), and analysis means (60) arranged around the incubator (20), as well as a loading device (40) for loading cuvettes (70) into the openings (21). The loading device (40) of the analyser (1) comprises a feed funnel (30), which is arranged to bend a straight cuvette (70) to fit the opening (21), and a ram (41), which is arranged to load a cuvette (70) into an opening (21) in the incubator (20) through the feed funnel (30).
