Frequently Asked Questions
1.Each reagent package must be examined before use. Product integrity may be compromised in packages that have been damaged. Inspect the package for the signs of leakage or moisture. If there is evidence of leakage or improper handling, do not use the reagent.
2.Pay attention to the expiration dates and open-container stability days of all the reagents. Be sure not to use expired reagents.
3.Pay attention to the storage temperature of the reagent (different reagents have different requirements, so you need to refer to the reagent label)
4.Do not ingest any reagent. In case of ingestion, seek medical attention promptly.
4.1. Avoid contact with skin. In case of contact, rinse the affected area immediately with ample amount of clean water.
4.2. Avoid contact with eyes. In case of contact, rinse the affected eye immediately with ample amount of clean water and seek medical attention promptly.
Generally, there are two types of expiration dates of reagents:
One is the storage expiration date of the reagent, that is, the final date on which the reagent can be stored under normal storage conditions (without opening the container);
The other is the open-container expiration date of the reagent, that is, the number of days during which the reagent can be used after the container is opened.
Different reagents have different storage expiration dates and open-container expiration dates, as well as different storage and use temperature requirements. You need to refer to the label or instructions manual of the specific reagent.
