Shelf life and stability data for the HSQ Kit™ has been studied and collected for 24-month periods many times for many years with no observed instability. Therefore, the expiration date is set for two years after the date of manufacture based on the stability testing done and to satisfy most customer internal policies.

Kits available for purchase will have at least six months left until the expiration date which should be a long enough period of time to properly use the kits..
