The present invention relates to a pipette dispensing block with an improved design for the piston chambers. In a multichannel pipetting block with a grid or array of pipetting piston of any order, the individual piston chambers are individually manufactured using the injection molding process. The individual piston chambers are assembled into a grid or single line array and held together by upper and lower plates in combination with either stabilizing posts or walls. The piston chambers are designed and assembled with a dual O-ring design at the tip and a tip sealing gasket at the bottom to provide the air-tight seal that is required for optimum pipetting performance. When combined with pistons and a motor-driven lifting plate for the pistons, the entire assembly forms a forms a multichannel pipetting block.

Provided is a technique for detecting deviation amounts in two directions between a tip of a nozzle of a pipetting device and a target stop position from one image. An imaging device of the present disclosure is an imaging device installed in a pipetting device including a nozzle that aspirates and dispenses liquid and an arm that holds the nozzle and moves the nozzle by a rotation operation. The imaging device includes: a camera that includes an image sensor and a lens; and a pair of mirrors that includes a first mirror having a first reflective surface and a second mirror having a second reflective surface. The pair of mirrors is arranged such that the first reflective surface and the second reflective surface face each other. The pair of mirrors is arranged one by one between the tip of the nozzle and a bottom surface of the arm, on both sides across a plane that includes a rotation axis of the arm and a central axis of the nozzle. The first mirror is disposed closer to the arm than the second mirror, with the first reflective surface facing toward the tip of the nozzle, and the second reflective surface facing toward the camera.

A pipette controller for aspirating and dispensing multiple aliquots of a fluid from a reservoir of fluid. The pipette controller may include a pipette holder adapted to operatively connect a pipette to the pipette controller; a pressure tank pneumatically connected to the pipette holder; a pump pneumatically connected to the pressure tank and configured to inject air into the pressure tank to create positive air pressure inside the pressure tank; an aliquot valve controlling airflow between the pressure tank and the pipette holder; and an electronic control. The electronic control may open and close the aliquot valve

A pipette controller with retractable stand includes a frame having a front end with a pipette connector and a rear end with a handle; a flat, lower surface on the handle; a retractable kickstand having arms and a arc-shaped base, rotatably fixed to the frame; an extended position retaining element on the frame having a pair of flanges that releasably retain the arms of the kickstand in the extended position; and an arc-shaped portion of the frame the corresponds to the base of the kickstand to provide a retracted position retaining element.

A disposable test cartridge and method for a point-of-care analyzer includes a cartridge body having a plurality of chambers where each of the plurality of chambers has an opening at a top of the cartridge body, a cartridge cover connected to the cartridge body where the cartridge cover has a capillary-receiving aperture, a capillary wiper disposed within the capillary-receiving aperture where the capillary-receiving aperture is aligned with one of the plurality of chambers of the cartridge body, and a capillary element removably insertable into the cartridge cover where the capillary element has a capillary tube that extends into the capillary-receiving aperture and through the capillary wiper where a tip portion of the capillary tube extends into the cartridge body.

A trace meter and a method for calibrating a dynamic ultra-micro pipetting device are provided, which relate to the technical field of dynamic pipetting precision calibration. The trace meter includes a measuring compartment, a temperature sensor, a pressure sensor and a controller. A top of the measuring compartment is open, the temperature sensor is provided at a bottom of the measuring compartment, the pressure sensor is provided below the measuring compartment, both the temperature sensor and the pressure sensor are electrically connected with the controller, the temperature sensor is configured to measure the temperature of liquid in the measuring compartment, and the pressure sensor is configured to measure the weight of liquid in the measuring compartment.

Provided is a pipette device that can discharge or withdraw a liquid easily by liquid processing operation by a robot device. Provided is a pipette device held by a robot device, comprising a driving part for withdrawing and/or discharging a liquid, a signal receiving part for receiving a signal from the robot device and a control part for controlling the driving part according to the signal.

A serological pipet for use with liquid handling may include a tip and a mounting portion with at least two sections with substantially circular cross-sections configured to fit into a pipet controller holder, the mounting portion may include a porous filter, The pipet may also include a tubular shaft with permanently marked volume indicating graduation marks. The tubular shaft may connect the tip and the mounting portion. A first section of the at least two sections and a second section of the at least two sections may have different diameters and a distance between the first section and the second section may be dimensioned to inscribe a cone having an angle of 11 degrees plus or minus 5 degrees. The tip, the mounting portion, and the tubular shaft may be made out of plastic resin.

Described herein are various fluid provision systems that may be used in a laboratory setting. The fluid provision systems minimize waste of pipetted liquid sample or reagents and may be used, e.g., in combination with a multi-well plate such as in NGS processes. Other systems include those configured for compatibility with centrifuge rotors or multichannel pipettes with 12 or more channels.
