  • Patent number: 5439646
    Abstract: A plurality of measuring modules are arranged on a table of a reaction part. The measuring module has one removable cell, and is provided with light sources and photodetectors. In proximity to the reaction part is a cell transfer part for mounting and dismounting the cell on and from the measuring module, a sampling probe for dispensing a sample into the cell, and a reagent probe for dispensing a prescribed reagent into the cell in response to a measurement item. A time from supply of each cell or dispensing of each sample to or in the reaction part to dispensing of a first reagent is controlled to be constant with no regard to the measurement items.

  • Patent number: 5207986
    Abstract: A rack supply part, an analysis unit part and a rack storage part are formed as units which are separable from each other, and a rack carrier part is integrally mounted on the analysis unit part. The respective units are provided with locating members for coupling the units in a direction for transferring a sample rack.Since the rack carrier part is integrated with the analysis unit part, relative positional relation between a position for stopping the sample rack and a position for stopping a sample dispensing pipetter provided in the analysis unit part for attraction is not displaced even if the units are separated from each other and then recombined with and mounted on each other. Thus, location is easy and no fine adjustment of positional relation is required.

  • Patent number: 4523484
    Abstract: A dilution pipetter comprising a diluent sucking probe, a sample probe for sucking and discharging a liquid sample, a diluent discharging probe disposed adjacent to the sample probe, a plunger pump of small plunger diameter selectively communicating with the diluent sucking probe or the sample probe by a first switching means, and a plunger pump of large plunger diameter selectively communicated with the diluent sucking probe, the sample probe or the diluent discharging probe by a second switching means. The dilution pipetter is useful as, e.g., an element of a clinical chemistry analyzer which is used to conduct numbers of reactions for small quantities of a liquid sample such as serum of the warm blooded animal including humans.
