Applications:
Target:
  • Somatic coliphages (e.g. PhiX174)
  • F-specific RNA bacteriophages (e.g. MS2)
Benefits
Drastically reduce the number of petri dishes used:
petri dishes instead of 20!
High recovery yields

Excellent concentration and elution yields for any kind of water.

1 PFU / 100 ml

Limit of detection compliant with the European requirements.

Analysis volume

Analyse from 10 to 100 ml with the same kit (possibility to scale up to 1 litre).

Handling time

Significantly reduce the analysis time.

What is required by the regulation?

Proving the absence of these viruses in water ensures the treatment’s efficiency against all viruses.

We have been using the VIRAPREP® kit routinely since the beginning of the year to concentrate somatic coliphages in water. Easy-to-use and fast, it meets our requirements in terms of efficiency. We now have the COFRAC accreditation for both direct and concentration methods for coliphage analysis.

The LD31 EVA uses the VIRAPREP® kit to concentrate the F-specific RNA bacteriophages. We obtain high recovery yields between 77% and 94% for drinking water and between 72% and 89% bottled water. The VIRAPREP® kit is handy and easy-to-use.
