Phenolphthalein is a highly sensitive presumptive test for the presence of blood. It remains the most practical and inexpensive method for testing suspected bloodstains from crime scenes. No more bulky hinged boxes or crushable ampoules to contend with. Our droppers are protected inside a simple, yet ergonomic, impact resistant plastic jar which fits comfortably in the pockets of your crime scene jacket or BDU’s. Our kit consists of three 15ml droppers conveniently labeled for easy use. This provides you with approximately 60 tests per reagent kit, making it both reliable and extremely affordable. Test kits are labeled with lot numbers and expiration dates so you never have to worry about the reliability of the test. A test sophisticated enough for the criminalist, yet simple enough for the patrol officer.
