An autoclaving microplate washing system for cells and non-adhering three-dimensional (3D) cell cultures includes one or more peristaltic pumps for controlling the dispensing of washing fluid and the evacuation of fluid from microwells to gently wash the cells.

A liquid surface imaging device includes an irradiator including a plurality of lightings, the irradiator configured to irradiate a liquid surface in a nozzle of a liquid discharge head with lights emitted from the plurality of lightings, and an imaging device configured to image the liquid surface. The plurality of lightings is arranged point-symmetrically with a center of the irradiator as a point of symmetry.

The present technology is directed to extraction devices, systems, and methods for controllably withdrawing and transferring fluid samples, such as blood, from a sample collection container to a testing device. For example, some embodiments of the present technology provide fluid extraction devices that include a fluid control module, a housing containing a receiving element and a suction element, and an actuator. To transfer blood from a sample collection container to a testing device, a user places the sample collection container over the receiving element and inserts the testing device into an outlet of the fluid control module. The user then pushes a lever or otherwise actuates the actuator, which automatically withdraws a predetermined volume of blood from the sample collection container and transfers it to the testing device positioned at the outlet of the fluid control module.

Disclosed is a specimen measurement device including a nozzle having an area on a distal end side being covered by a hydrophobic coating; a measurement unit that measures a specimen dispensed into a container by the nozzle; and a drive unit that moves the nozzle so as to abut on a bottom surface of the container, in which the nozzle having a distal end surface on a discharge port side being exposed from the hydrophobic coating.

A capillary of the present disclosure has a tubular shape, both ends of which are a first end and a second end in a length direction and are open, an inner surface of which has water repellency and has a portion where a degree of the water repellency changes. A pipette of the present disclosure includes the capillary and a pipette main body to which the capillary 10 is attached, and the pipette main body has a pressure chamber that is deformable and connected to the capillary.

A method for calibrating and controlling a pipetting device for metered liquid with a multichannel, automated micrometering unit. All of the channels of the pipetting device are calibrated using a camera which detects the expelled droplets of the liquid, so that the volume thereof can be determined by means of a control device. The method makes it possible to carry out a calibration of the individually dispensed liquid volumes in droplet form to a prescribed volume deviation with a different number of possibly necessary repetitions for each individual channel.

In example implementations, a method is provided. The method may be executed by a processor of a fluid dispensing apparatus. The method includes receiving a request to lock a plurality of dispensers in the fluid dispensing apparatus. A confirmation is detected that each one of the plurality of dispensers is filled with a respective fluid. An unlock command is received to allow each one of the plurality of dispensers to dispense the respective fluid. The respective fluid is dispensed in accordance with the unlock command.

The present invention relates to a method and a system (400) for filling a closed container (200) with a fixative solution. The system comprises a container (200) comprising a container body (230) for receiving a biological specimen, a lid (220) for selectively closing the container body (230) and a port (100) forming a unidirectional barrier in a direction from the inside (IC) to the outside (OC) of the closed container (200). The system further comprises a dispensing apparatus (500) having a filling nozzle (300) for dispensing the fixative solution. The filling nozzle (300) is relatively moveable with respect to the container (200) between a retracted position and a filling position to fill the container (200) with the fixative solution.

A system may include a horizontal actuator to move a tray, to which a microwell plate and a microfluidic chip may be coupled.
