In a method and device for assessing the quality of a processing operation, a workpiece with specific processing parameters is processed along a processing trajectory. The (X), wherein the processing result is measured by at least one sensor and at least one sensor signal is recorded and at least one quality parameter is determined based on at least one sensor signal and the at least one quality parameter is compared with quality parameter threshold values to assess the quality of the processing result. During the assessment of the processing operation quality, changes made to the processing parameters from target values during the processing are automatically taken into consideration, in that, instead of the quality parameter threshold values, quality parameter threshold values adapted to the changes in the processing parameters are determined, and the at least one quality parameter for assessing the quality of the processing result is compared with the adapted quality parameter threshold values.

A system and method for ejecting one or more fluids from a digital dispense device. The method includes a) inputting to a memory a volume per unit area for each of the one or more fluids to be ejected from the digital dispense device; b) matching the volume per unit area to a device resolution for the digital dispense device; c) formatting fluid ejectors for the digital dispense device for the device resolution; and d) ejecting fluid from the digital dispense device to provide the volume per area for each of the one or more fluids.

Apparatus and methods are provided including imaging a blood sample that is a cell suspension deposited in a sample chamber. The cells are allowed to settle in the sample chamber to form a monolayer of cells. At least one microscopic image is acquired of the monolayer of cells using a microscope (24) while the microscope is focused at a monolayer-depth-level, and a first platelet count of platelets that have settled within the monolayer, is determined. An additional microscopic image of the simple is acquired, while the microscope is focused at a different depth level from the monolayer-depth-level, and a second platelet count of platelets that have not settled within the monolayer is determined. An output is generated based upon the first and second platelet counts. Other applications are also described.

A cassette holder holds a cassette for medical use. It includes a cassette receiving portion that includes a bottom surface to which a lower surface of the cassette is brought into contact when the cassette is set, and a plate-shaped portion that is provided in the cassette receiving portion, has a substantially plate-like shape, and extends substantially parallel to the bottom surface, and a protrusion inside of which is hollow, the protrusion being provided to the bottom surface to protrude downward. The bottom surface and the protrusion are provided with a plurality of through holes.

Provided are an active droplet generating apparatus capable of controlling a droplet size, a method of controlling a droplet size using the same, and a self-diagnosis apparatus for diagnosing generation of a droplet, the active droplet generating apparatus including: a disposable microchannel upper plate; a multifunctional lower plate separated from the disposable microchannel upper plate and configured to be permanently used separately from the disposable microchannel upper plate; a functional polymeric film provided on a lower surface of the upper plate; a negative pressure forming means; and a flow velocity control device configured to adjust the droplet size to a desired size by receiving, by feedback, the voltage value measured by the droplet measuring electrode and controlling flow velocities of the oil and the sample, thereby controlling the droplet size in a feedback control manner by quickly and accurately measuring the droplet size using a capacitance impedance technique.

The invention relates to a method in the preparation of samples for microscopic examination onto which a coverslip is applied. The method is notable for the fact that the coverslipping quality is checked automatically and at least partly optically. The invention further relates to an apparatus for carrying out the method, and to an apparatus for checking the coverslipping quality of samples onto which a coverslip is applied.

An apparatus for providing an object to be medically examined by blowing is provided where air is blown into a container in which an object to be medically examined is stored, so as to make the uniform distribution state of the object to be medically examined from the inside of the container, thereby ensuring the sameness of the object to be medically examined, which is to be extracted from the container.

There is provided a sample processing cartridge comprising a. a sample entry location; b. a closed sample processing chamber; c. a sample analysis location comprising a sample analysis well; d. a first channel fluidly connecting the sample entry location and the sample processing chamber; e. a second channel connecting the sample analysis location and the sample processing chamber, the second channel comprising a closed or closable second channel valve; wherein the sample processing chamber comprises a second channel port providing fluid connection between the second channel and the sample processing chamber, the second channel port being positioned in a sample accumulating region of the sample processing chamber. There is also provided a sample processing system comprising the cartridge, and methods of use of the cartridge and processing system in a sample processing assay.

The object of the invention is to perform, rapidly and at a low cost, a pretreatment of an analysis sample containing a turbid substance. Provided is an analysis sample pretreatment apparatus in which a clarified liquid is obtained by removing a turbid substance from an analysis sample. The analysis sample pretreatment apparatus includes a cell configured to store the analysis sample, and a cell holder in which at least a part of a housing is opened to mount the cell. The cell holder includes an ultrasonic wave transducer and an ultrasonic wave reflection plate that are disposed on facing plane pairs while sandwiching the cell mounted inside the cell holder. The cell includes a first opening unit from which the analysis sample flows in, a second opening unit from which the clarified liquid flows out, and a third opening unit from which the turbid substance is discharged. In a state where the cell is mounted in the cell holder, the first opening unit is provided at a position lower than an upper end of the ultrasonic wave transducer in a vertical direction, or at a position higher than a lower end of the ultrasonic wave transducer in the vertical direction.
