Delvotest SP100NT (100 test/bx), dsm

DELVOTEST SP 100 NT is a standard diffusion test for the detection of residues of antibacterial substances in food samples. The test contains solid agar medium seeded with standardised number of spores of Bacillus stearothermophilus var. calidolactis together with required nutrients for growth purposes and antifolate trimethoprim. DELVOTEST SP 100 NT allows food producers to test their products for antibiotic residues which ensures food safety. It provides sensitivity for antibiotics like Penicillin G and Sulfadiazine at low concentrations. When added to the test, food samples which are free from antibacterial substances, or contain them below specified levels will allow germination and growth of the bacteria leading to a change in the indicator colour. This helps food companies meet regulatory standards and prevent contamination in their products.
