An automatic analyzer maintains accuracy of analysis of a specimen even when a liquid spills on an expendable item case. The automatic analyzer has an expendable item case which accommodates expendable items including a dispensing tip used for dispensing a specimen and a reaction cell used for reaction between the specimen and a reagent, and a conveyance portion which conveys the expendable items from the expendable item case. A body cover covers the analysis unit, the expendable item case, and the expendable item conveyance portion. The expendable item case includes a tray in which the expendable items are arrayed, and an expendable item cover which covers the tray and in which an open portion through which the expendable item conveyance portion passes is provided on a side surface thereof, and the expendable item cover includes a barrier portion protruding upward at an end on a side of the open portion.

The present disclosure describes systems and methods for centering a circular object, such as a petri dish, between a plurality of pins. For example, in one embodiment, a method comprises placing a circular object on a rotatable platform surrounded by three moveable pins. In order to roughly center the circular object, the method further comprises moving, for a first time, all of the pins toward the circular object until at least two out of the three pins are touching the circular object. In order to more accurately center the circular object, the method further comprises: moving all of the pins away from the circular object so that it can be rotated without substantial inference; rotating the platform approximately 60 degrees, wherein rotating the platform causes the circular object to also rotate by approximately 60 degrees; and moving, for a second time, all of the pins toward the circular object.

A blood analyzer according to one or more embodiments may include: a specimen preparation part that prepares a measurement specimen by mixing a reagent into a blood preparation; a measurement part that measures the measurement specimen; a measurement mode selection unit that receives an input of a type of blood preparation as a measurement target selected from a plurality of types of blood preparations; and a controller. The controller may cause the specimen preparation part to prepare the measurement specimen depending on the selected type of blood preparation.

An automatic analyzing apparatus according to the present embodiment includes a specimen container, a piercer, a detector, and processing circuitry. The specimen container is a container in which a specimen is housed, an opening of the specimen container being sealed by a cap. The piercer pierces the cap by a distal end. The detector detects a blot on the cap. The processing circuitry controls a piercing operation of the piercer.

Provided herein is an automation device for identifying and collecting biological agents, which improves user convenience and enhances operational efficiency by integrating the collection and identification processes. The automation device includes: a collection unit including a movable filter tray; and an identification unit disposed apart from the collection unit and configured to wash and store collected biological agents, where a filter assembly may be mounted on the filter tray, the filter assembly being configured to collect biological agents by passing external air through a filter, and the filter coupled inside the filter assembly may be configured to automatically rotate as the filter tray moves to the identification.

A container unit for handling containers includes a support surface arranged with a plurality of seats. Each of said sets is adapted to contain a container, and each container is provided with a container data carrier adapted to contain a unique identifier of the container. The container unit comprises at least one container unit data carrier adapted to contain data of the containers contained in the seats, said data comprising the unique identifiers of each container, and the position of each container in the seats. A nest locator is provided on the surface of the container unit. The nest locator is adapted to be the reference for mapping the position of the containers in the seats.
