Compact Dry ETB


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.

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.
Presentation: Packs of 4 units
Mode of use:
  1. Remove the cover.
  2. Deposit 1 ml of the sample in the center of the surface of the Compact Dry plate.
  3. The sample is automatically and homogeneously dispersed on the film, and transforms the dry film into a gel in a few seconds.
  4. Replace the cover on the plate. Incubate for the prescribed time.
Weigh the sample
