CompactDry Plates


A variety of organism-specific and total count tests, packaged up nicely in a sophisticated and sturdy cassette.
The benefits are easy to spot.

Rigid Transparent Cassette with  Removable Lid

Keep your colonies intact with space between the media and lid. Easily remove the plastic lid for quick inoculation. Count your colored colonies clearly through the gridded back surface of the cassette.

Self-Diffusing Media

1ml sample dropped in the middle of the plate turns the dry media to gel that diffuses evenly and automatically on the plate. No need for a spreader, no need for an extra step.

Designed to Stack

Save precious incubator space with a product that is designed to stack
in the incubator with low risk of contamination.


Keep storage simple with plates that come with long shelf lives and can be stored long term at room temperature.


Aspergillus has four main species of concern: A. niger, A. flavus, A. terreus, and A. fumigatus. Many state regulations require testing for Aspergillus but only a few require speciation of the “Big Four.”
