A mechanism (10) for an automated Karl Fischer (KF) titration system (1) includes a support console (6), a first vertical guide rail element (11), solidly attached to the support console, and a carriage unit (12), slidably constrained to the first vertical guide rail element, allowing the carriage unit a first degree of linear vertical mobility relative to the support console. The carriage unit holds a vial lift unit (13) with a lift platform (14) for a sample vial (18). The carriage unit, in a downward movement phase, lowers the lift platform from a starting position into an oven cavity of the titration system. A subsequent upward movement phase raises the lift platform to the starting position. A second vertical guide rail element, solidly connected to the lift platform and slidably constrained to the carriage unit, enables a second degree of linear vertical mobility of the lift platform.

Embodiments of the present disclosure relates to a sample stainer for automatically staining samples with one or more reagents. The stainer comprises a trough base with predetermined pattern to hold one or more trough. Each trough comprises a plurality of compartments that is capable of being filled with one or more reagents required for staining samples. The stainer also comprises a slide holder for holding slides having sample collected from the users. The slide holder comprises a plurality of compartments, each compartment comprising one or more slots to hold the slides. The stainer further comprises a motion control unit that is configured to control the rotary motion of the trough base and linear motion of the slide holder during the staining process. The stainer also comprises a user interface configured to receive inputs including slide information and staining process related information from user to perform the staining of the sample.

A sample injector for chromatography 10 where air or moisture can be prevented from getting mixed in when a sample is injected is provided with a syringe 11, a syringe drive unit 13, a turret 12 in which sample vials 4 are placed, a turret drive unit 14, and a control unit 30 that controls the syringe and turret drive units 13 and 14. The configuration includes a housing 15 having a gas introduction port 15a and a gas discharge port 15b that communicate with the inner space, where the syringe 11 sucks a sample from a sample vial 4, the sucked sample is injected into the sample vaporizing chamber 23 in a chromatograph 20, and a predetermined gas is introduced through the gas introduction port 15a, and at the same time, a predetermined gas is discharged through the gas discharge port 15b when a sample is analyzed.

An apparatus for transferring liquid between a fluid module rotating around a rotation axis and a transfer module rotating around the rotation axis comprises a first drive effecting rotation of the fluidic module to move a fluid opening of the fluidic module oriented in a first direction along a circular path around the rotation axis. The second drive rotates the transfer module to move a transfer opening of the transfer module oriented in a second axial direction with respect to the rotation axis along a circular path around the rotation axis. The first direction and second direction correspond to axial directions opposite to each other. The rotation of the fluidic module and the rotation of the transfer module are synchronized to position the fluid opening and the transfer opening relative to each other to allow liquid transfer between the transfer opening and the fluid opening during the rotations.

An analyzing apparatus is described, a representative one of which includes: rotatable table arranged with a plurality of holes for accommodating the reaction container which includes a specimen and a reagent; and a container transferring section, arranged on the rotatable table, for transferring the reaction container.

A soil fractionation system can include a plurality of sample racks propelled by a drive system. Each sample rack can include a sample tube for holding a soil sample and a filter cup for receiving an extracted fraction of the soil sample. An extractor module of the fractionation system can include an extractor assembly and a filter assembly. A control system can control the relative positioning of the plurality of sample racks via the drive system, the relative movement between the extractor assembly and the sample tube, and the relative movement between the filter assembly and the filter cup.

A first drive mechanism of a dispensing probe device moves a first support arm in a vertical direction and rotates the first support arm in a horizontal direction. The second drive mechanism moves a second support arm in the vertical direction and rotates the second support arm in the horizontal direction. A distance from a rotation center of the first support arm to a second dispensing probe in the horizontal direction is longer than a distance from a rotation center of the second support arm to the second dispensing probe in the horizontal direction. A fan shape having an arc formed by a trajectory of one end of the second support arm that is far from the rotation center of the second support arm is included in a fan shape having an arc formed by a trajectory of the second dispensing probe.
