How to Get the most from your CompactDry™
plates and The Wizard™ CompactDry™ Reader

Whether your lab is an established CompactDry™ user or in the process of validating its
use, it is important that the proper use of the CompactDry™ plate products will greatly
enhance the performance of The Wizard CompactDry™ Reader. Please note these im­portant points and refer to the IFU (Instructions For Use) for each of the CompactDry™
plates:

• Carefully read through each section of this manual and the IFU for each Compact­Dry™ plate, conveniently located within the Hardy website, HardyDiagnostics.com

• Validate sample matrices and adjust settings as needed according to this manual
before use.

• It is highly recommended to use a stomacher bag and filter the homogenized sam­ple prior to inoculation to eliminate carry over of tiny particles onto the surface of
the CompactDry™ medium. Small particles may interfere with photo optic detection
mechanism.

• During and after incubation, keep the lid tight on the plates to avoid any possible
dehydration.

• An additional dilution may be needed when the sample has a dark color, which is
can be indicative of a high bioburden. Individual colonies may not be distinguishable
on trays if concentrations are above 100 CFU/ml. In general, additional 1:10 dilutions
will allow colonies to be visualized. The Wizard™ CompactDry™ Reader has a maxi­mum detection limit of 150 CFU; however the sample should be diluted to a concen­tration of less than 100 CFU/ml for best results. Refer to the procedure section and
general dilution guidelines in the IFU for each plate type.
