Abstract: A device for manual fine metering of a substance, in particular in powder form, provided with a manual transport tool (24), also having a movable part (32) configured to be induced to vibrate by a motor and wherein the transport tool (24) is held against the movable part (32) in order to induce the transport tool (24) to vibrate. An electronic scale (10) provided with a device of this type enables better manual metering.

Abstract: A sampling method, fluid collection system, and auxiliary sampling device to assist an autosampler in collecting samples from a fluid source. The sampling device includes a support frame and a motorized actuator, with a piston, attached to an end of the support frame. A sample arm has an upper end disposed at an end of the support frame opposite the motorized actuator and a lower end with an inlet to receive a fluid sample. A cable and pulley mechanism links the sample arm to the piston. A fluid conduit within the sample arm has a fluid intake end connected to the inlet and a fluid discharge end connected to an autosampler. The cable and pulley mechanism pivots the sample arm when the motorized actuator pushes or retracts the piston to position the inlet at desired positions within the fluid source so that the autosampler collects multiple samples at various depths.

Abstract: A sampling method, fluid collection assembly, and auxiliary sampling device to assist an autosampler in collecting samples from a fluid source. The auxiliary sampling device includes a support frame with a pivot member. A linear actuator having a piston is attached to the support frame. A rotatable sample arm assembly has an upper end attached to the piston and to the pivot member of the support frame, and a lower end with an inlet to receive a fluid sample. A fluid conduit within the sample arm assembly has a fluid intake end connected to the inlet and a fluid discharge end connected to the autosampler. The linear actuator pushes or retracts the piston to vertically pivot the sample arm assembly until the inlet reaches desired positions within the fluid source so that the autosampler collects multiple samples at various depths.

Abstract: The powder sampling device comprises, next to a vertical channel (1) a drawer that is also vertical which may be lowered so that a groove (5) passes into a sampling mouth (12). A flap (15) may be extended to direct the powder towards the groove (5) temporarily and fill it, without the drawer (4) or the flap (15) disrupting the flow in normal circumstances nor causing any residue of powder likely to alter the measurements. In particular, the flap (15), the groove (5) and the corbelled section (2) have faces (6, 8) that are heavily angled on which the powder can only slide.

Abstract: A liquid pipetting apparatus for dispensing liquid of minute volume for use in a survey instruments of a hemanalysis machine, a genetic screening, and a pharmaceutical screening, etc., is disclosed. The liquid pipetting apparatus comprises a liquid holding member for holding the liquid, and capable of dispensing the liquid from one end, and a driving member for moving the liquid holding member forward and backward along the dispensing direction, the liquid holding member being moved by the driving means, thereby dispensing the liquid held on the liquid holding member.

Abstract: An apparatus for drawing and supplying multiple samples for rapid processing in flow cytometry. The apparatus comprises a reciprocating valve and at least one syringe. The invention is also a method for rapidly processing multiple samples in flow cytometry using the apparatus.

Abstract: A pipetting station having a bottom sensing device is provided in conjunction with one of any known liquid level sensing devices. The bottom sensing device includes a pipetting probe spring mounted to a pipetting arm of the pipetting station. The bottom sensing device also includes a sensor for determining when a pipetting tip of the pipetting probe is in contact with a bottom of a tube. The bottom sensing device permits the pipetting probe to measure an exact volume of fluid in the tube by allowing the pipetting tip to be lowered to the bottom of the tube beyond the sensed fluid level.
