Delvotest® SP-NT 100ct
Delvotest® SP NT is designed to test milk for the presence of antibacterial substances such as antibiotics. The Delvotest® SP NT test is made of an agar gel containing bacterial spores and a pH indicator. The milk sample is added onto the agar gel, and the Delvotest® SP NT test is placed for incubation at 64 degrees C. The principle of the Delvotest® SP NT test is based on the diffusion of possible inhibitory substances that may be present in the milk sample into the agar. This reduces growth and acid production by the test organism and delays or prevents the agar from changing color from purple to yellow. The present report includes all technical details about the Delvotest® SP NT and the results of the validation study. The validation study demonstrates that the Delvotest® SP NT conforms to the product performance claims and confirms the robustness of the test. The Delvotest® SP NT is therefore granted Performance Tested Method(SM) certification.
The Delvotest® is the most widely used antibiotic test for the detection of antibiotic residues in milk and dairy products globally. Delvotest® is the only broad spectrum test in the world with the ability to detect the widest range of antibiotics in a single test and have AOAC and/or AFNOR certification. The original Delvotest® test required the addition of a nutrient tablet before the addition of milk during testing. Further development of Delvotest® has seen the tablet removed and incorporated within the agar and therefore no tablet was needed. That’s why the abbreviation SP NT now stands for Sulphadiazine Penicillin No Tablet.
Designed for use on the farm, Delvotest® SP NT is a standard diffusion test with high sensitivity to most veterinary antibiotics. No tablet is required, just add milk to the Delvotest® SP NT ampule. Delvotest® SP NT provides easy-to-read results, indicated by color, in under 3 hours. Delvotest® SP NT is intended for use with cows, sheep, and goats. Delvotest® SP NT is not intended for NCIMS use. Delvotest® SP NT offers a long kit shelf life. Each Delvotest® SP NT kit contains individual ampules containing Bacillus stearothermophilus, a dosing syringe, disposable pipettes, tweezers, and instructions.
