A simple, reliable, and economical test for antibiotic residues in milk with results in 2-1/2 hours. Delvotest detects a broad spectrum of antibiotics—not limited to the penicillin family. Designed for use on the farm or in a laboratory, this standard diffusion test has high-sensitivity to most veterinary antibiotics. Results are indicated by color. Self-contained, except for the required block heater, each kit contains individual plastic ampules containing Bacillus stearothermophilus in a solid medium, nutrient tablets (not required for SP-NT), dosing syringe, disposable pipets, tweezers, and instructions.
