2+2 Method (Schering)

"Zones of Inhibition"

Calculations

Performs all calculations in accordance to the Schering Plough 2 + 2 Method. The software calculates the mean and standard deviation values for both the reference and unknown zones and several statistical values.

Plate Reading

The OMNICON Zone Reader reads each 100 mm petri dish in less than 1 second, measuring the diameter and shape of each zone. The shape value is used to exclude zones which are elliptical due to spills or irregular growth.
