Abstract
An apparatus which permits simultaneous use as reaction vessel for taking up one or more reaction liquids, for incubating and storing these liquids and for carrying out optical measurements is described. The apparatus performs functions of the reaction vessel and functions of the apparatus for liquid uptake. This makes it possible for analysis to be completely free of carryover while, at the same time, requiring minimal use of consumable materials or rinsing solutions.
Claims21
An apparatus for taking up, transporting and storing a liquid and for carrying out optical measurements, comprising:
- a reaction vessel having a body which enables the storage of the liquid, the body being formed by walls, at least two walls being sufficiently transparent to permit light transmission for optical testing, a base portion of the reaction vessel forming a cuvette portion;
- a liquid aspirating device extending into the body of the reaction vessel to such an extent that between an upper outlet of the liquid aspiring device and a bottom of the cuvette portion a volume is defined, which is at least the volume of the liquid to be stored;
- and
- a connecting device for connecting the reaction vessel to an exchangeable tip unit, the connecting device being located on an upper side of the reaction vessel.
