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 chromogenic plates are suitable for both in-process and final product controls.
Compact Dry ETB is used to detect enterobacteria quickly and easily. Enterobacteriaceae are unequivocally detected by means of specific substrates.
Specifications:
| Matrix: | Raw materials, finished products, environmental samples from the food, cosmetics and pharmaceutical industries, among others. |
| Incubation time and temperature: | Incubate at 35 ± 2 °C for 24 ± 2 hours with AOAC, at 37 °C for 24 hours with MicroVal and at 37 ± 1 °C for 24 ± 2 hours with NordVal. |

Mode of use:
- Remove the cover.
