Instant mixing device for sample subpackaging

Abstract

The invention provides an instant mixing device for sample subpackaging. The instant mixing device comprises an inner bottle cap, an outer bottle cap, an inner bottle and an outer bottle, wherein mutually corresponding ratchets are arranged on the inner side of the inner bottle cap and the outer side of an opening in the top of the outer bottle cap, and the inner bottle cap and the outer bottle cap are connected through the ratchets; inner lock catches are arranged on the outer side of a bottle body of the inner bottle; outer lock catches are arranged on the inner side of the neck of the outer bottle, and mutually correspond to the inner lock catches of the inner bottle; the inner bottle and the outer bottle are mutually fixed through the matching of the inner lock catches and the outer lock catches, and threads are arranged on the inner side of the neck of the inner bottle cap; threads are arranged on the inner side of a cap body of the outer bottle cap; threads are arranged on the outer side of the neck of the inner bottle and the outer side of the neck of the outer bottle; the inner bottle is respectively screwed on the inner bottle cap and the outer bottle cap through thread openings. The instant mixing device for sample subpackaging, provided by the invention, can solve data distortion of samples, and is used for unstable samples, particularly preparation and storage of standard substances and samples for laboratory comparisons and quality control.

Description

technical field [0001] The invention relates to the technical field of experimental containers, more specifically, to an instant mixing device for sample packaging. Background technique [0002] Stability is an important attribute of reference materials, but it also limits the development and application of some reference materials with unstable characteristics, such as low concentration or unstable samples in solution state. [0003] On the other hand, in laboratory comparison or quality control activities, it is increasingly required that the comparison or quality control samples have multiple concentration levels, and the concentration and matrix are close to the actual detection samples. For example, in water quality testing, the contents of heavy metal elements and volatile organic compounds in common inspections are all on the order of ng / mL. Such low concentration levels pose new challenges to the stability of samples. [0004] The traditional method is to provide hi...
