Description

technical field

[0001] The invention relates to the improvement of the cuvette for analysis and its manufacturing method, in particular to a high-precision cuvette and a method for bonding the cuvette glass sheets to each other. Background technique

[0002] The cuvette used for quantitative analysis and holding the test solution is a glass vessel with a liquid storage test chamber formed by bonding several optical glass sheets to each other. The existing cuvette glass sheets are bonded to each other through an adhesive (glue) bonding and glass frit fusion bonding) bonding. Glue bonding is to apply glue on the mutual bonding surfaces for bonding, such as described in Chinese patent CN00807831.9. This kind of bonding, due to the poor temperature resistance of the glue, the cuvette is not resistant to high temperature, usually the highest can only withstand about 100 ℃, beyond this temperature the adhesive will lose its effect and cause degumming; secondly, the adhesive is ge...
