A device to perform immunological, histochemical and cytochemical, molecular biological, enzymological, clinical-chemical and other analyses, wherein the device comprises:
- an object holder having at least one elongate adhesive surface having one dimension longer than an orthogonal dimension;
- and
- a reagent holder having at least one elongate channel having one dimension longer than an orthogonal dimension, each elongate channel configured to receive a respective elongate adhesive surface,
- wherein the object holder is detachably connectable to the reagent holder in such a manner that each elongate adhesive surface nests between walls of a respective channel, and in case reaction partners bound to a solid phase are disposed on each elongate adhesive surface and reactants dissolved in liquid are present in each channel, the reaction partners and the reactants are in contact, and wherein means are provided for preventing the liquid from passing from one channel to an adjacent channel where more than one channel is present.
