CompactDry™ Listeria spp (LS) from Hardy Diagnostics provides a ready-to-use, self-diffusing chromogenic medium for the isolation, presumptive identification, and enumeration of Listeria species from food, cannabis, environmental, and cosmetic samples.

Colonies of Listeria spp. develop a distinct blue coloration due to the presence of chromogenic substances, allowing for rapid and accurate differentiation without additional reagents or confirmation steps.

Designed for efficiency, accuracy, and ease of use, CompactDry™ LS simplifies microbial testing by eliminating media preparation and agar pouring. Each plate is pre-sterilized and shelf-stable at room temperature, making it ideal for field, manufacturing, and laboratory environments.

Each cassette contains four easily separated plates, supporting multi-sample or dilution testing from a single unit.

Features and Benefits:
• Ready-to-use format — eliminates media prep and reduces testing time
• Blue colony reaction enables visual identification of Listeria spp.
• Room temperature storage — no refrigeration required (unlike competitor systems)
• Compact, stackable plates — maximize incubator space
• Self-diffusing media — ensures uniform colony growth and clear differentiation
• Durable cassette design — four connected plates easily snap apart
• Leak-proof and easy to label
• Ideal for food, cannabis, and environmental testing laboratories
• Supported by Hardy Diagnostics technical and regulatory expertise
