It can be easy to lose the cap for a drug test or have someone come behind you and throw it away not knowing it was in use, and the flip top specimen container will help prevent this from happening. You can shop for drug tests here at our online stores and find the ideal container for collecting samples that works for your program. We have inexpensive wholesale drug test kits for sale that can test anywhere from one to fifteen substances, as well as adulterations. All you have to do is decide what purpose you want the drug test kit to serve and what drugs you want to sample for.
