Abstract: A container or consumable like a reaction tube for use in diagnostic assays. The present disclosure provides a system for fluid handling and transport, comprising a plate with at least one cavity for receiving a fluid which is surrounded by a rim, and a separate cover comprising a centrally arranged surface as a sealing element which is surrounded by a rim, wherein the plate or the cover comprise at least one snap-fit mechanism for connecting at least two plates, at least two covers or a plate and a cover, wherein the snap-fit mechanism extends upwards or downwards from the surrounding rim of the plate or the cover, and wherein the rim of the plate or cover which is to be connected is configured for accommodating the snap-fit mechanism of an upper or lower plate or cover in a retaining element arranged at the rim.

Abstract: The present disclosure provides an aqueous composition comprising a purified thermostable polypeptide with biological activity, and a purified thermolabile water-soluble substance which in a functional conformation at a permissive temperature absorbs light and/or exhibits fluorescence, wherein the maximal permissive temperature of the polypeptide is above the maximal permissive temperature of the substance. The present disclosure further provides methods employing such a composition, and kits containing ingredients to form such a composition.

Abstract: A container for an access-controlled storage system having a plurality of compartments designed to contain an article where access to the article is controlled by granting access to one or more compartments at a time without moving the article, wherein control is provided by a rotary belt with a cut-out directed by deflection pulleys; and an access-controlled storage system having at least two containers and a housing wherein control of the container is actuated to grant access to one or more defined compartments within the container.

Abstract: The present invention relates to a container for an access-controlled storage system comprising a plurality of compartments, each compartment designed to contain an article, and a control means to control the accessibility of said compartments, wherein said control means is capable of granting access to the article of only one compartment at a time without moving said article, wherein said control means comprises a rotary belt with a cut-out directed by deflection pulleys. Another aspect of the present invention is an access-controlled storage system comprising at least two containers according to the present invention, a housing, and an actuating means capable of actuating the control means of said container, wherein said actuating means grants access only to a defined compartment within said container.
