The way that medical products and devices are packaged and sealed is vital. In fact I don’t think it is an exaggeration to say that it can, literally, be a matter of life and death. That is why regulators around the world apply strict standards to the methods used to package devices and to the testing regimes to ensure that the packaging is properly sealed and that the seal will remain intact while the product is transported and stored. Many countries for example adopt the universally accepted standards devised by ASTM International (formerly the American Society for Testing and Materials).
Shelf life is the length of time that foods, beverages, pharmaceutical drugs, chemicals, and many other perishable items are given before they are considered unsuitable for sale, use, or consumption.
A major advantage for using the TriStar II with the Krypton Option is the ability to measure low surface areas. Although the TriStar II standard nitrogen system can measure surface areas as low as 0.01 m2/g, the Krypton Option enables you to measure areas as low as 0.001 m2/g and provides increased accuracy for materials under 1.0 m2/g. Krypton is also useful for analyzing materials that are difficult to sample or have very low density; pharmaceutical lubricants, for example.
Krypton is an excellent choice for low surface area measurements. At 77 K, nitrogen has a saturation pressure of 760 torr, whereas krypton has a saturation pressure of only 2.5 torr.
An international manufacturer of nutritional products needed to improve its tablet coating process. The OEM-supplied spray bar in use was over-wetting tablets and causing quality defects including picking and sticking problems.
