Usage of Compact Dry TC is a simple and safe test procedure for determination and quantification of aerobic mesophilic count in foods, cosmetics or raw materials – as well as pharmaceutical raw materials. The ready-to-use plates consist of a special 50 mm diameter petri dish containing a detection specific nutrient pad.
The “aerobic mesophilic count” indicates the number of colony forming units (cfu) formed on a plate count medium during a specified incubation time at mesophilic temperatures (approx. 30 – 37 °C). The aerobic count is an indicator for the microbial status of the production and environmental conditions.
Compact Dry TC contains a standard nutrient medium for detection of total plate count. Due to the tetrazolium salt which is integrated into the medium and serves as redox indicator die, the grown colonies will be red colored and therefore easily to identify and differentiable from possible food residues on the plate.
The ready-to-use, chromogenic Compact Dry plates are suitable for in-process controls as well as controls of finished products. With the optional additional product Promedia ST-25 swab test (Z0302) or Compact Dry Swab (ZCS1002953) Compact Dry plates may also be used for surface sampling and therefore applied for quantitative hygiene monitoring even at surfaces which are difficult to reach.
- Compact Dry TC is therefore an extremely easy-to-use method and also convincing due to the high time saving; a confirmation test is also not necessary.
