Copper Assay in 8 Minutes NEW Eberbach
ULTRA-SPEED ELECTRO-ANALYZER Where determination time is critical or where volume production of determinations is urgent, this new equipment is your answer. Most determinations require approximately one fourth that of conventional apparatus; initial investment is less than for equivalent production capacity in conventional equipment. An analytically complete deposition of a one gram copper sample takes 8 minutes or less. Best equipment previously required 30 to 60 minutes. Improved cell design, a unique electromagnetic field and more current produce the speed.
