Delvotest BLF® – antibiotics in milk


NEW! Fast test for main antibiotic found in milk – betalactam.

Delvotest BLF is a revolutionary new fast test that allows you to test milk for Betalactam in just five minutes. Bectalam is the main antibiotic found in milk. This is a test for a single antibiotic, not a broad spectrum test.

Previously, a test took far longer to prove that milk is safe to use. This new testing kit minimizes the time and effort required from farmers and dairies. No laboratory equipment is needed.
