Antibiotic discs

Drag a disc code onto the agar. The stock stays in place so you can reuse it.

• Incubate – after placing discs, click to simulate growth and show inhibition zones.
• Measure – click the button, then click a disc to place a draggable ruler for measuring.
• Interpret – once zones are measured, click to classify each antibiotic as Sensitive, Intermediate, or Resistant.
• New plate – reset the agar plate and start fresh.
• Demo – auto-place sample discs so you can try the features quickly.
