Container for liquid analysis

Abstract

The present invention discloses a container for liquid analysis. The container comprises a first container portion and a second container, which are connected; a first groove, a first through hole and a second through hole are arranged on the first container portion; the second container portion is provided with a second groove; the space between the first groove and the second groove forms an analysis cavity, an inlet channel and an outlet channel; a channel port from the inlet channel to the analysis cavity and a channel port from the analysis cavity to the outlet channel are respectively distributed on both sides of a line between the center of the on the space between the first through hole and the analysis cavity; the inlet channel includes a gradually expanding first channel section; and the distance between the two through holes is not less than half of the distance between the two channel ports. A gradually expanding channel section is adopted in the invention to ease the impulsive force of the liquid entering into the inlet channel; a certain distance is between the two through holes, so that suction heads placed between two through holes can uniformly adsorb liquid overflowing from the two through holes. Therefore, the container ensures accurate and reliable results on liquid optical analysis.

Description

technical field [0001] The invention relates to the technical field of liquid analysis, in particular to a container for analyzing liquid. Background technique [0002] In the fields of life sciences, medicine and health, food and environmental protection, it is often necessary to analyze liquids, especially the components of liquids. There are various methods for analyzing liquids, which generally include the analysis, separation and detection of liquid samples, such as the separation of protein peptides in the field of life sciences, the analysis of beverage components in the food field, the research on drug components in the pharmaceutical field, and the Field analysis of body fluids such as urine, plasma and serum, etc. [0003] Optical detection is a commonly used means of liquid analysis. It uses optical instruments, such as microscopes, to observe the liquid to obtain information about the composition of the liquid. It is especially suitable for the analysis of body ...

Problems solved by technology

Since this prior art vessel for analyzing liquids locates the inlet orifice 12 and the outlet orifice 13 in the middle vessel region between two adjacent corners, which are very close to each other, one of them is removed during centrifugation. Or two spilled liquids will pool around both of them, when using a suction trap (which has a ~2mm tip) to suck up the spilled liquid, the tip of the suction trap must be closer to the center of the two wells. One, so the suction force of the liquid in the hole and the channel connected with it is greater, and it may happen that a part of the liquid in the hole and the channel connected with it is sucked in order to suck up the overflow liquid, resulting in the analysis space The liquid in 29 flows to this channel, affecting the test results
