Introduction of desiccant for blood sugar test paper container

Sep 30 , 2022

Blood sugar test strips are disposable consumables for daily blood sugar testing of diabetics. Its components contain enzyme reagents, so the moisture resistance of blood sugar test paper buckets is relatively high. In order to ensure the desiccant in the internal environment, there will be a desiccant on the lid of the package. The type of desiccant is mainly silica gel, molecular sieve or an equal proportion mixture of the two.

Silica gel desiccant is a transparent or milky white granular solid. It has an open porous structure, strong adsorption, and can adsorb a variety of substances. Its suitable hygroscopic environment is room temperature (20-32°C) and high humidity (60-90%), which can reduce the relative humidity of the environment to about 40%, so the application range of silica gel desiccant is very wide. It is not only used as a special material in aviation, cutting-edge technology, military technology sectors, but also in various sectors of the national economy, which has expanded to: construction, electrical and electronic, textiles, automobiles, machinery, leather and paper, chemical light industry, metal and paint , Medicine, etc.

Silica gel is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has many characteristics that other similar materials are difficult to replace. It can effectively control the number of water molecules in the blood sugar test strip barrel for a long time, maintain the stability of the internal environment, and prevent the blood sugar test strip from getting wet.

Silica gel and molecular sieve desiccant have their own characteristics. In order to make good use of their moisture resistance, a mixture of the two in equal proportions will be selected in the blood sugar test paper bucket to protect the stability of the test paper within the validity period.
