Description

Technical Field

[0001] The utility model belongs to the technical field of experimental equipment, and particularly relates to a colorimetric tube holder. Background Art

[0002] A colorimetric tube is a main instrument for analyzing experiments by visually observing with the naked eye or measuring the absorbance with a photometer in chemical detection experiments. It can be mainly used for measuring the concentration of solutions. When performing colorimetry, the colorimetric tube containing the solution to be measured and a colorimetric tube containing a standard solution are placed in front of a white paper with the same illumination degree for comparison. The color difference is observed with the naked eye or the absorbance is measured with a photometer. The wall of the colorimetric tube is thinner than that of an ordinary test tube, so the colorimetric tube needs to be carefully placed on the colorimetric tube holder.

[0003] The existing colorimetric tube holders are single-row with 6 holes or 12 holes, or multi-row with multiple holes, and most of them are made of wood or plastic in three layers. The diameter of the hole positions is larger than the diameter of the colorimetric tube. During the process of carrying the colorimetric tube holder, the colorimetric tubes collide with the colorimetric tube holder, generating a large amount of noise. The outer diameter of the colorimetric tube is slightly larger than the diameter, and there is a possibility that the mouth of the colorimetric tube cannot fit into the hole position when draining water.
