Compact Dry TCR
Description:
Compact Dry is a simple and safe procedure for determining and quantifying microorganisms in foodstuffs, cosmetics and other raw materials, including pharmaceuticals. The ready-to-use Compact Dry LM food chromogenic plates are suitable for both in-process and final product controls.
Compact Dry TCR plates within their composition contain nutritional components that promote rapid growth of microorganisms, allowing enumeration after 24 hours ofincubation. .
The aerobic colonies present a red coloration, due to the tetrazole salt (redox indicator), facilitating theenumeration of the colonies and allowing them to be distinguished from possible sample residues. .
Specifications:
| Matrix | Raw materials, finished products, environmental samples from the food, cosmetics and pharmaceutical industries, among others. |
| Incubation time and temperature: | 5 ± 1°C or 32 ± 1°C for dairy matrices. |
| Presentation: | Packs of 4 units |
Mode of use:
- Remove Cover.
- Deposit 1 ml of the sample in the center of the surface of the Compact Dry plate.
- The sample is automatically and homogeneously dispersed on the film and transforms the dry film into a gel in a few seconds.
- Replace the cover on the plate. Incubate for the prescribed time.
