摘要： A dosing and mixing apparatus for fluid media comprising at least one delivery element and one isolating element. These elements are provided with through-flow or transfer passages and dosing chambers suitably mutually arranged for accomodating and isolating a voluminized specimen quantity or measured dose of test specimen as well as for delivering this measured out dose of test specimen to and mixing this dose of test specimen with a measured dose of thinning agent. The dosing and mixing apparatus manifests itself in that at least one channel suitably associated with the dosing chamber is provided in a surface of one of the elements, such as the isolating element at the surface thereof which faces the delivery element. Each such channel communicates with through-flow openings or circulation passages and is traversed by a cleansing fluid wetting the mutually facing and touching surfaces of the individual delivery and isolating elements in the transport path of the dose of test specimen.

摘要： An apparatus for the detachable connection of an axially to-and-fro movable piston of a syringe with a piston rod or plunger, comprising at least two holder brackets arranged in mutually spaced relationship from one another at the piston plunger and formed of a spring wire, detachably secured with said piston plunger. Each holder bracket essentially comprises two respective axially extending webs and a connection element or piece arranged transversely with respect to said webs. The piston of the syringe possesses a headpiece formed as a substantially truncated cone and equipped with a contact edge engaged by said connection pieces.
