CompactDry™ Enterobacteriaceae (ETB) is a ready-to-use, chromogenic culture medium designed for the rapid and reliable enumeration of Enterobacteriaceae in food, cannabis, cosmetics, and environmental samples. This group of bacteria serves as a critical hygiene indicator in food production and quality control environments.

The CompactDry™ ETB system simplifies microbial testing by combining dehydrated media and a pre-poured plate format that rehydrates instantly upon inoculation with 1 mL of sample. Colonies develop as distinct red or purple spots due to chromogenic reactions, allowing for easy identification and accurate counting — even by less experienced technicians.

Features and Benefits:
• Detects and enumerates Enterobacteriaceae through chromogenic colony color (red/purple)
• AOAC validated (Certificate No. 012001) for reliability and reproducibility
• No spreader or preparation required — simply add 1 mL of sample
• Self-diffusing media ensures even distribution without air bubbles
• Stable at room temperature (1–30°C) — no refrigeration needed
• Compact, stackable format ideal for space-efficient incubation
• Enables subculture recovery without damaging colonies
• Long shelf life and easy-to-label rigid cassette design
• Supported by Hardy Diagnostics’ industry-recognized technical service team

CompactDry™ ETB supports compliance with global food safety and cannabis testing standards while reducing hands-on time and minimizing waste.
