New Chromogenic Microval Approved Total Count Plate Validated for all Foods

Compact Dry TC

Compact Dry TC has received the first ever MicroVal approval according to ISO 16140 requirements, and is the first chromogenic medium to be validated by Microval for the detection of total counts in ALL food samples.

Compact Dry plates are ready-to-use dry media sheets comprising culture media and a cold soluble gelling agent, rehydrated by inoculating 1 ml diluted sample into the centre of the self-diffusable medium.
