Reagent bottle

A combination of a sample analyzer and a reagent bottle;

• said sample analyzer including an air inlet element and a sample inlet element;
• and said reagent bottle comprising a hollow body which provides a first side that defines both a sample discharge opening and an air inlet opening, said sample discharge opening and said air inlet opening respectively defining axes which are parallel to each other, both said sample discharge opening and said air inlet opening docking onto said air inlet and sampling elements of said sample analyzer when said reagent bottle is inserted into said sample analyzer;
• an elastic, pierceable stopper which is sealingly positioned in said discharge opening to define an external aide facing away from said body and an internal side which faces a interior of said body;
• and a protective foil which-covers said external side of said stopper;
• said-stopper defining a first recess in said external aide to provide a first puncturing site where said sampling element of said analyzer can puncture said foil, and a first prepunctured, tightly and elastically closed sealing area which extends in a direction between said first recess and said interior of said body.

A combination of a sample analyzer and a reagent bottle, said sample analyzer including an-air inlet element, a sampling element, a receiving element with connecting line connected to a vacuum pump, and a feeding unit with media feed line and media level measuring element;

• and said reagent bottle comprising a hollow body which provides a first side that defines both a sample discharge opening and an air inlet opening, said sample discharge opening and said air inlet-opening respectively defining axes which are parallel to each other, both said sample discharge opening and said air inlet opening docking onto said air inlet and sampling elements of said sample analyzer when said reagent bottle is inserted into said sample analyzer;
• an elastic, pierceable stopper which is sealingly positioned in said discharge opening to define an external side facing away from said body and an internal side which faces an interior of said body;
• and a protective foil which covers said external side of said stopper;
• said stopper defining a first recess in said external side to provide a first puncturing site where said sampling element of said analyzer can puncture said foil, and a first prepunctured, tightly and elastically closed sealing area which extends in a direction between said first recess and said interior of said body;
• said reagent bottle being connectable to said sample-analyzer such that said connecting line thereof extends through said elastic stopper and said feed line and said media level measuring element thereof extend through said air inlet opening.
