  • Patent number: 12044692
    Abstract: A countersunk hole is added to a back surface of a dispensing chip mounting position of a sample dispensing chip installation table such that, when the dispensing chip is pulled up from the installation table, the amount of contact of a chip side surface is reduced and the chip is stably mounted. In addition, a posture control member during falling is added to a chip waste position, and the chip is caused to fall vertically and attachment of a sample to a waste route is suppressed. When a dispensing probe moves upward during dispensing chip separation, an upper end of the chip is moved upward up to a position in contact with a base and stopped and then is moved upward again. Thus, the posture of the chip during separation is stable. Further, plural positions for separating the chip are provided such that the position changes depending on waste timing.
