FAQ7: How long can I use FertiCult Flushing medium after opening the bottle?
2 factors limit the shelf life of a product after opening the bottle:

  • Gass exchange: influences the pH
  • Contamination with viable organisms

  • We have performed open bottle tests on our media for up to 7 days and found that the product parameters stayed within the specifications in this time period, taking into consideration that the bottle was opened under sterile conditions and the product was stored at 2-8°C after opening.
