Introduction
The 741MD-SS Series is simple to use and will
operate many millions of cycles without maintenance.
The 741MD-SS is a pneumatically operated,
adjustable needle valve designed to apply precise
microdeposits of low to high viscosity fluids down
to fractions of a microliter. It is ideal for automated
assembly processes that require small dispensing
tips (from 22 to 33 gauge). The 741MD-SS provides
exceptional control and the absolute minimum dead
fluid volume.
