SMLD300 is a
miniature, high precision, Swiss-made micro-valve fabricated to the highest
European standards. These valves are individually QC tested and adjusted to
assure accuracy and consistency. The SMLD300 valves enable the
Dispensing/Aspirating Device to provide accurate dispensing down
to 20 nl with CVs of <5%. The SMLD300 is available as a component or as a
A sapphire to ruby valve seat
(hard on hard surface interface) assures a well-defined, precise
dispensation with minimal adhesion, retention and accumulation of reagents.
The valve orifice is designed to reduce flow turbulence and
eliminate satellite droplets, adding to the overall accuracy of the
dispensing process. Micro valve dimensions enable use in tight linear or
matrix arrays. An example of 8 x 12 matrix with 9 mm spacing is shown on the
array of SMLD valves is shown above for illustration purposes.
The valve is energized
by a short 12 VDC pulse (1 to 2 msec), followed by a 3 VDC (RMS) holding
voltage. Valve’s opening and closing time is close to 1 msec. The valve will
operate at pressures of up to 30 PSI.
Valve drivers are available and TechElan
can provide information on optimal pressure selection for better
dispensing accuracy, re-suspension of
compounds, reduced splashing and other liquid
