General description

GranuCult® plus Letheen Agar Base is used for the microbiological sampling of environmental surfaces that are treated with disinfectants. It is a highly nutritious medium containing Lecithin and Tween® 80 for neutralizing quaternary ammonium compounds contained in sanitizers. Beef extract and tryptone provide nitrogen, carbon, sulfur, and other essential growth factors. Glucose is the source of energy, and agar is the solidifying agent. The media is a modification of the AOAC formulae.

Application

GranuCult® plus Letheen Agar is used to neutralize quaternary ammonium compounds, for sampling of environmental surfaces that have been treated with disinfectants.

Features and Benefits

  • GranuCult® offers superior granulated culture media.
  • Safe and sustainable due to reduced risks associated with fine dust and toxic substance inhalation, resulting in a safer work environment.
  • Excellent wettability, solubility, and free-flowing properties
  • Convenient, with minimal component separation and clumping, even under warm or humid conditions.
  • High batch-to-batch reproducibility
  • Prolonged shelf life of up to five years
  • High number of test strains exceeding all regulatory demands
  • Granulation technology allows many supplements to be included, with no need to add these separately
