Lynn Peavey Company's QuickCheck is a presumptive testing kit that simplifies in-the-field narcotics identification testing. A wider, crystal-clear pouch with a white background allows officers to easily and accurately view the results. The pouch's rounded bottom prevents the drug sample from slipping into the corners. The bag comes with a collection device and fetures a convenient zip closure. Foldout instructions attached on every kit provide step-by-step directions for a successful test. A chemical-resistant disposable bag is included to safely place the completed kit in when done. Test kits are available for cocaine, heroin, two types of Marijuana, methamphetamine, ecstacy and Marquis. QuickCheck's expanded lineup also features new cocaine swabs.
