- Burner
- Flame
- Matches
- Tape
Method:
- Ethanol was used to clean the work station
- A maker was used to dived each equal sections and ruler and was label with appropriate concentrations.
- The plate carefully open
- The disc was soak in the different concentrations of ethanol
- Placed one disc per concentration for each labelled section
- The plate was tape shut
- The plate was returned to the incubator
- The zone of inhibition was recorded after 3 days.
