Application
The BOECO SA dispenser supports a very wide range of applications for the dispensing of aggressive reagents - directly from the supply bottle:
Such as concentrated bases and acids like H3PO4, H2SO4 (with certain exceptions such as HCL, HNO3, HF, etc.), saline solutions, and a variety of organic solvents.
Specially for use in trace analysis for dispensing high-purity and highly concentrated acids and salt solutions, acids, alkalies and many organic solvents as well as hydrogen peroxide, bromine.
