  • Commercially available Formaldehyde contains 30-40% HCHO the rest 60-70% is water
  • The sensitivity of the embryos is very high between 24th -84th hour of incubation

In order to neutralize the smell of formaldehyde inside rooms after fumigation we can spray with 10% ammonia aqueous solution.
