Various photometers such as spectrophotometers, fluorophotometers, and turbidimeters are used in the analysis of raw materials in the chemical industry and the analysis of biological components in medicine. Measurements using these photometers are carried out by placing a sample (hereinafter referred to as the sample) in a transparent sample container (cell or test tube) made of glass or plastic with a light-transmitting surface, and placing the sample in the sample container holder installed in the sample chamber of the device. (hereinafter referred to as a sample container holder), close the lid of the sample chamber, and expose the sample to light from a light source in a dark room to detect the light that has passed through the sample or the fluorescence generated when excited by the incident light. A method is used in which measurements are carried out using

可能であるため拡く普及する傾向にある。 On the other hand, as the use of photometers has become extremely widespread and the number of specimens to be measured has increased, a sample sipper method has recently become popular as a method for increasing the efficiency of measurement. This is a method in which a flow cell (called a flow cell) is provided inside the sample chamber, and the sample is sucked in through a nozzle provided outside the sample chamber using a suction pump. Measurements can be made by simply inserting the nozzle into a test tube containing a sample and pressing a switch. In addition, by combining an autosampler that rotates the test tubes side by side, it is possible to continuously and automatically measure a large number of samples, so it is becoming more popular.
前述のサンプルシツパー方式の測定方法は次の
ような欠点がある。
The sample sipper measurement method described above has the following drawbacks.
(1) 吸引ポンプなどが必要で構造が複雑になるた

ければならない。 For this reason, on the one hand, the sample sipper method is becoming popular, but on the other hand, the measurement method mentioned above, in which the sample container is placed in the device and the measurement is performed directly, is also becoming more popular.
This measurement method, which is widely used as a basic method, involves opening the lid of the sample chamber for each sample to be measured, inserting the sample container into the sample container holder, closing the lid, performing the measurement, and then repeating the measurement again. You have to open the lid and take it out.

特徴とする光度計。 In a photometer that illuminates a sample in a sample container with light from a light source in a sample chamber and detects transmitted light of the sample or fluorescence generated from the sample with a detector, the sample container is located at a measurement position in the sample chamber. and a vertically movable sample container holder positioned at a standby position for receiving the sample container at its upper part;
provided at the sample container insertion port of the sample container holder,
The sample container is inserted through an automatic opening/closing lid that opens when the sample container rises and closes when it descends, and a member that contacts the lower end of the sample container when the sample container is inserted into the sample container holder. a detector that detects the insertion of the sample container; and when the detector detects that the sample container is inserted, the sample container holder is lowered from the standby position to the measurement position, and the measurement is performed by applying light from the light source. and a control device for raising the sample container holder from the measurement position to the standby position when the measurement is completed.
