New SNAP Tetracycline Test Kit: We’ve changed the test procedure to match our New SNAP Beta-Lactam test kit—now you can run them side by side with a 5 minute incubation and a 4 minute color development. In addition, this new test kit is less sensitive and will detect the following drugs in raw commingled cow milk at or below these levels: tetracycline 50 ppb, chlortetracycline 100 ppb and oxytetracycline 50 ppb.
(Mfr. Item # 99-11470) 20 tests per pack.
