Replace the conditioning solution
WARNING
Inhalation hazard. Do not breathe Diisopropylamine (DIPA) or ammonia fumes. Exposure may result in
severe injury or death.
WARNING
Chemical exposure hazard. Diisopropylamine (DIPA) and ammonia are a flammable, corrosive and
toxic chemical. Exposure may result in severe injury or death.
WARNING
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Read the safety data sheet from the supplier
before bottles are filled or reagents are prepared. For laboratory use only. Make the hazard information
