CompactDry™ vs Petrifilm™: A Comparison of Enumeration Procedures
|
|
|
|
|
Today, we delve into a detailed workflow comparison of two ready-to-use dehydrated culture media systems: CompactDry™ and Petrifilm™. We'll explore their respective workflows, highlighting their efficiency, accuracy, and suitability for various applications. Join us as we uncover the differences and similarities between these two popular culture media solutions.
|
|
|
Remove the protective cap from the CompactDry™ plate. CompactDry™ plates do not require refrigeration, and are ready to use immediately.
Then, label each plate with a dilution factor ranging from 10⁻¹ to 10⁻⁸.
|
|
Once our dilutions are prepared, we are ready to plate.
Simply lift the cover of one CompactDry™ and use a pipet to transfer 1ml of solution into the center of the plate.
|
|
|
CompactDry™ plates do not require spreading or stamping. The specimen will diffuse automatically into the CompactDry™ plate, transforming the dry medium to gel. The space between the media and the cover lid allows colonies to form three dimensionally.
|
|
Re-cap the plate, and the tray is ready for incubation. The unique design of CompactDry™ plates allows unlimited stacking.
|
|
|
Count the colonies by hand or by using the Wizard™ automated colony counter. The Wizard™ is a standalone plate reader with LIMS connectivity capabilities for use with CompactDry™ plates.
You can see how the Wizard™ CompactDry™ Reader works in our video.

Pet Food Forum / Food Safety Summit
|
|
|
This month, Missy White and Mark were proud to share our environmental monitoring solutions April 29-May 1 at the Petfood Forum in Kansas City.
|
|
Next, they travelled to the Food Safety Summit in Chicago, May 5-9. Mark is always deeply grateful to have the privilege to travel to events like these where he gets the opportunity to learn from industry leaders.
|
|
