Provided are a blood collection device and a blood collection method enabling blood collection from any subject in the necessary amount for a test. The blood collection device is provided with a compression mechanism that independently compresses the base section and/or the middle section and the distal section of a finger, and collects blood from a puncture mark on the fingertip by repeatedly compressing the finger in the order of the base section and/or the middle section and the distal section. This blood collection device is characterized in that a period of time for compressing the distal section is longer than a period of time for compressing the middle section and/or a period of time for compressing the base section.

Provided is a mass spectrometer capable of ensuring a work space for maintenance or the like of a turbomolecular pump as compared with one in the related art. A mass spectrometer 10, 10A, 10B includes: an ion source 30; a vacuum chamber 40 into which a sample ion ionized by the ion source 30 is introduced; and a turbomolecular pump 50, 50A, 50B configured to maintain the vacuum chamber 40 in a vacuum. The turbomolecular pump 50, 50A, 50B is provided above the vacuum chamber 40 in a vertical direction.

In order to provide an automatic analyzer capable of improving the measurement stability, the following configuration is adopted. A control unit acquires a photometric waveform for each of a plurality of reaction cells held on a reaction disk from a photometry signal based on a photometry trigger signal, and sets a photometric value calculation period based on a time domain, the photometry signal being obtained by executing photometry of the plurality of reaction cells in an empty state or in a state where blank water is accommodated, the photometry trigger signal representing that each of the plurality of reaction cells crosses an optical axis of a light source, and the time domain representing a flat waveform obtained regarding the photometric waveform for each of the plurality of reaction cells .

An object of the present disclosure is to avoid a decrease in liquid height measurement accuracy due to deviation of a measurement device and lens aberration when measuring a biological sample having one or more component regions. A biological sample measurement device according to the present disclosure acquires a distortion coefficient and a liquid height conversion coefficient from a captured image of a calibrator having a pattern shape on a surface thereof, and corrects a liquid height of a sample based on the distortion coefficient and the liquid height conversion coefficient (see Fig. 1).

Provided is an automatic analyzer including: a vacuum bottle configured to receive a cleaner used in a cleaning mechanism; a vacuum tank connected to the vacuum bottle; a vacuum pump configured to evacuate the vacuum tank; and a cylindrical aspiration nozzle configured to discharge the used cleaner aspirated from the cleaning mechanism into the vacuum bottle, in which the aspiration nozzle vertically extends in the vacuum bottle, has a lower end surface that faces downward and is blocked with an end wall, and includes a discharge port that is formed sideways.

Provided are a column cartridge and an analyzer by which an operator can safely and easily replace a separation column while preventing an increase in cost and environmental burden. The column cartridge according to the present invention includes: a separation column having a built-in stationary phase; a heat transfer body configured to transfer heat from a heating mechanism to the separation column; and a housing configured to accommodate the separation column and the heat transfer body. A heat insulating layer is formed between the heat transfer body and the housing. The heat insulating layer is preferably a gap formed at a position excluding a plurality of support portions that support the heat transfer body.

The purpose of the present disclosure is to provide a technique capable of stably gripping an object when the gripping mechanism is not suitable for gripping the object by sandwiching the object. A gripping device according to the present disclosure is provided with a gripping part that grips an object having a first hole and a second hole. The gripping part is provided with: a first rod-shaped member that positions the object by being inserted into the first hole; and a second rod-shaped member that prevents the object from rotating by being inserted into the second hole (see fig. 4B).
