Features

Digital Indications of antibiotic zone diameter using a micro-computer.
Measurement range 00.00 to 35.00 mm diameter readability 0.01mm.
Average of two diameter readings in vertical & horizontal direction of inhibition zone.
Recall average diameter of 4 inhibition zones.
Key operations are acknowledged by beep sound.

The antibiotic zone reader provides a rapid accurate method for determining the strength of antibiotic materials by measuring the diameter of an inhibition zone in a petri-dish.

In use, the discs are placed on a petri-dish prepared with agar and inoculated with bacteria. After incubation, the bacteria cover the entire dish except for a circular inhibition zone around, it being a function of the strength of the antibiotic.

This zone reader measures the diameter of the inhibition zone to 0.02 mm within range of 0 to 35 mm diameter. Light from a source from the top, passes through the transparent and semitransparent portions of the agar, then to a reflecting mirror supported by an arm above the unit. The mirror reflects the light to glass prism mounted at the front of the unit and magnified image of the zone of inhibition is clearly visible.



Advantages :

1. An accurate method of determining the strength of antibiotic materials.
2. Magnified image of the inhibition zone is clearly visible on the prism.
3. Less time-consuming for measuring the accurate diameter of an inhibited zone.
4. Easy to operate for single person.
5. Display shows direct reading
