There are several requirements for the transportation of laboratory standards.

There are several requirements for the transportation of laboratory standards: 1 The transportation conditions of general standards, compared with the long-term preservation conditions, the transportation process is relatively short, so the transportation conditions are relatively strict without storage conditions. Standards with long-term storage conditions of normal temperature and +4 degrees can be transported under normal temperature conditions. Standards stored at -20 degrees can be placed in ice packs to reduce temperature during transport, while materials stored at -80 degrees need to be added during transport. dry ice. However, the effective time of dry ice can only last for about 1 day, so this type of material is not suitable for long-distance transportation. 2 Usually not shipped by ice or cold storage. The storage conditions indicated on the standard bottle or package are used to protect the functional integrity of the standard during long-term storage. The transport conditions depend on the stability information and shipping time of each standard. If there is scientific evidence that USP standards should be transported with ice or dry ice, USP will do so.
