Antibiotic Multi-Test Discs – Mixed Gram Positive/Negative (Pack of 50)

NOT FOR HUMAN OR ANIMAL CONSUMPTION

These high-quality Antibiotic Multi-Test Discs (MASTRING-S®) provide a convenient and effective method for testing the susceptibility of bacteria to a range of antibiotics. Supplied in a great value pack of 50, each disc features 8 antibiotic-impregnated tips, enabling simultaneous testing against both Gram-positive and Gram-negative bacteria.

Designed for microbiology applications, these multi-test discs allow the equivalent performance of multiple individual antimicrobial susceptibility tests in a single step, saving time while delivering clear and reliable results. The discs are supplied in a sealed storage container to maintain quality and sterility.

For optimal performance, store at 2–8°C and allow the discs to reach room temperature before use. When applying to agar plates, ensure good contact using sterile forceps or a sterile needle.
