That's because they will have to sample and catalog millions of chemical combinations. To meet this need, engineers at Parker Hannifin's General Valve Operation, Fairfield, N.J., have designed the Oligo Series of valves. A newly designed perfluoroelastomer diaphragm gives the valves a life of over 10 million cycles (dry cycle testing). The low-coefficient-of-friction diaphragm and PEEK valve body make the valves compatible with the most demanding bioanalytical chemistries.
The isolation solenoid valves use a standard two-way, normally closed configuration powered by 24 Vdc. Fluids flow through a 0.060-in. orifice, with 1Z
