Pack of 50 Mast discs impregnated with specific doses of the antibiotic penicillin. Use in conjunction with a petri dish inoculated with bacteria to see the effectiveness of different antibiotics against different bacteria. Also available are blank discs which can be used as controls.
We recommend using disc ejectors to make dispensing the discs onto agar far easier.
Please note that we have recently transferred supply from an alternative manufacturer so some of the discs supplied may not be Mast branded.
