Abstract: The present invention provides for a single-use, disposable container and methods and apparatuses for testing liquid samples in a non-destructive fashion using the single-use, disposable container within a liquid sample analyzer. The single-use, disposable container reduces the overall sample volume contact within a flow path of the liquid sample analyzer, decreases the cleaning solution and drying time needed between sample analyses, and minimizes formation of particles during use of the container.

Abstract: A mixer insert (1) for a static mixer, comprising a plurality of mixing elements (3, 3a, 3b, 3c, 3d, etc.) which are disposed one behind the other along a longitudinal axis (L) and preferably immediately adjoin each other and each comprise a plurality of crossing rods (8, 9; 10, 11), at least two mixing elements consecutive along the longitudinal axis (L) among the plurality of mixing elements (3, 3a, 3b; 3b, 3c; 3c, 3d; etc.) being turned relative to each other by a twist angle of preferably 90° with respect to the longitudinal axis (L), the mixer insert (1) being composed of multiple separate mixer-insert parts (2, 2a, 2b) which each extend along the longitudinal axis and which are disposed adjacent to each other perpendicular to the longitudinal axis (L), each mixer-insert part (2, 2a, 2b) having a plurality of mixing-element parts (14, 14a, 14b, 14c, 14d, etc.; 15, 15a, 15b, 15c, 15d, etc.
