Description

Technical Field

[0001] The utility model relates to the technical field of sample stability analysis, in particular to a coring sample bottle for a stability analyzer. Background Art

[0002] A stability analyzer analyzes sample stability based on transmitted and scattered light signals. In a stability analyzer, a light source, transmitted light detector, and backscattered light detector are mounted on a platform that is driven up and down by a motor. The light source illuminates the sample, and the platform scans the scattered and transmitted light signals perpendicular to the sample. This analyzer measures the sample's instability over time, spatial distribution, and temperature, providing a quantitative instability index, sample layer thickness, particle migration velocity, and a curve of particle size variation over time.

[0003] During the test, the stability analyzer scans the vertical height range from the bottom of the bottle to the top of the sample. After signal collection is complete, the top surface of the sample must be manually selected as the calculation range. Therefore, the flatness of the sample's top surface greatly affects the signal quality and the final calculation results. Generally, the flatter the top surface, the higher the signal quality and the more reliable the test results.

[0004] Common sample bottles are round glass bottles with an open top, and samples are loaded from the top using a pipette or dropper. The sample falls to the bottom of the bottle due to gravity. For samples with low viscosity and good fluidity, the upper surface of the sample can be spread to a relatively flat state in a short time and can be tested immediately. However, for samples with higher viscosity and poorer fluidity, such as pastes and slurry samples with extremely high concentrations, loading the sample from the top often does not result in a flat upper surface. The upper surface of the sample requires a long waiting time to spread to a relatively flat state. During the loading process, bubbles or holes that are difficult to remove are easily formed in the sample, and the sample is extremely easy to stick to the wall, which will cause invalid stray signals of transmission and scattering during the stability test, affecting the test results.
