A gripper having a mechanical coupling that can be connected to a pipetting tube, at least one fluid channel extends from the coupling and a negative pressure can be transmitted, the gripper having at least one suction cup that is connected to the coupling through the at least one fluid channel as a result of which the negative pressure can be transmitted from the coupling to the at least one suction cup, and the at least one suction cup in the intended use position of the gripper is aligned such that a rim of a suction cup of the at least one suction cup is aligned in a substantially vertical plane.

The invention further relates to a method for producing said pipetting device. The invention relates to a pipetting device, in particular for pipetting a fluid sample by suctioning into a pipetting container using air under a pipetting pressure, having the following:a valve assembly with at least one valve device for adjusting a pipetting pressure, said valve device having a valve chamber;at least one pump device which is connected to the valve chamber in order to generate a chamber pressure in the valve chamber;a pipetting channel which is connected to the pipetting container, anda bypass channel which is open towards the surroundings, whereinthe pipetting channel and the bypass channel are each connected to the valve chamber; andthe at least one valve device has a closure element with a closure surface which is designed such that the chamber pressure is distributed to the pipetting channel and the bypass channel in a metered manner by the valve device in order to generate the desired pipetting pressure in the pipetting channel. The invention further relates to a method for producing said pipetting device.

Operability, accuracy, and safety when fitting a glass-made pipette tip to a pipette are improved. A pipette tip fitting adapter includes a hollow body having one end portion configured to serve as a tip inserting portion into which a pipette tip is inserted, and the other end portion configured to serve as a pipette inserting portion into which a pipette is inserted, and at an opening side of an inner circumferential surface of the tip inserting portion, seal portions projecting inward are formed in a circumferential direction. Accordingly, a pipette tip that is long and heavy like a glass tip can be held.

The invention relates to a holding apparatus for holding a pipetting container, in particular a serological pipette, at a pipetting apparatus, comprising a tubular connecting section that is configured to hold the tube-shaped end of a pipetting container in a pipetting position by means of a clamping connection, a clamping connection device that is arranged at the connecting section and that comprises a spring device for the establishment of the clamping connection and an air chamber device for releasing the clamping connection by means of a vacuum. Furthermore, the invention relates to a pipetting apparatus with that holding apparatus.

An automatic dispensing device includes a gripper configured to grip a dispenser having a discharge nozzle with the discharge nozzle facing downward, a tip rack arrangement portion configured to arrange a tip rack in which pipette tips to be attached to the discharge nozzle are accommodated, a biasing member configured to bias the tip rack arrangement portion from below, and a moving unit configured to move the gripper relative to the tip rack arrangement portion.

A pipette controller for aspirating and dispensing multiple aliquots of a fluid from a reservoir of fluid. The pipette controller can include a pipette holder adapted to operatively connect a pipette to the pipette holder; a pump having a vacuum port and a pressure port, the pump pneumatically connected to the pipette holder; an aspirate valve that controls airflow between the vacuum port and the pipette holder; a dispense valve that controls airflow between the pressure port and the pipette holder; a piston chamber; an aliquot dispense pump including a piston having a shaft that extends into the piston chamber, the shaft defining a stroke length; and an aliquot check valve that connects the pipette holder and the aliquot dispense pump; wherein the aliquot valve opens to allow airflow into the pipette holder upon engagement of the aliquot dispense valve. The pipette controller can also include a piston pump pneumatically connected to the pipette holder configured to deliver a bolus of air to the pipette holder.

The present invention relates to a suction device (1) to be used together with a pipette, in particular a Pasteur pipette. The suction device comprises a base element (2) with the bore (2a) for the insertion of a pipette (5), and a body connected to the base element, wherein the interior of the body is hollow, wherein at least the body is made of a flexible material, so that the inner volume of the body (3) is variable. Herein, the base element is formed in a polygonal or elliptic shape, so that the shape of the base element is not round and hence prevents a rolling of the suction device over a lab bench or the like.

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 cartridge for evaluating the volume of an aliquot of liquid is described. The cartridge can have one or more well tabs that pivot into a position in which liquid dispensed into a corresponding well is placed in contact with a capillary and surface tension draws the liquid from the well into the capillary. Comparison of the liquid-air interface with markings on or near the capillary, can reveal the volume of liquid dispensed. One or more additional features, such as well tabs that are stable in a substantially vertical orientation and/or a groove for protecting and/or self-aligning the capillary can ensure that the device operates properly.

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.
