    We have chosen the high density polyethylene (HDPE) plastic material for its peculiar characteristics, i.e. resistance to chemical attack of saline, acid and alkaline solutions, as well as solvents such as alcohol, esters and ketones, and for its resistance in environments from ph 2 to ph 12 - without any effect for possible evaporation of sulphates and sulphides.
