Glass containers   are one of the main packaging materials used in the pharmaceutical industry. A large number of pharmaceutical preparations have been packaged in glass containers, which are often the packaging material of choice.     Why Use Glass in Pharmaceutical Packagin? Glass is an inorganic material (mainly silicates) or a mixture of materials that solidifies without crystallizing when heated and then cooled. Glass has been used as one of the primary materials for medical packaging solutions for decades. Packaging for pharmaceuticals must be of the highest quality because the integrity of the product must not be compromised under any circumstances. The type of glass container used as a pharmaceutical packaging material is specific to the contents of the package. This is because the glass container is in direct contact with the preparation. The packaging should not react physically or chemically with the drug, which could lead to changes in product quality. Glass offers many adv

Principle and Precautions of Vacuum Blood Collection

A   vacuum blood collection tube   is a disposable, negative-pressure vacuum glass tube that enables quantitative blood collection and needs to be used in conjunction with a venous blood collection needle.      Principle  The principle of vacuum blood collection tube is to pre-pump the capped blood collection tube into different vacuum degrees, and use its negative pressure to collect venous blood samples automatically and quantitatively. One end of the blood collection needle is pierced into the human vein and the other end is inserted into the rubber plug of the vacuum blood collection tube. The human vein blood inside the vacuum blood collection tube, under the action of negative pressure, through the blood collection needle into the blood sample container, in a venipuncture, can achieve multiple tube collection without leakage. The volume of the inner chamber of the connected blood collection needle is very small, so the effect on the volume of blood collection can be neglected, an
