With a width of only 4.5 mm, Type 6650 sets a new standard in medium Envelope Dimensions [mm] (see datasheet for details)
isolation miniature solenoid valves. The optimized design enables
reproducible and precise dosing, good rinsing capability and is suitable
for the application of aggressive chemicals owing to the high quality of
the materials used. With the two nominal sizes of 0.4 and 0.8 mm, as
well as the selection between 2/2-way and 3/2-way function, it is ideal
for applications where the highest fluid performances are required in
the smallest space. Type 6650 opens up new possibilities, owing to the
4.5 mm station width, in particular in connection with dosing in 384-well
micro titer plates. C
