A method and apparatus for dispensing small quantities of viscous materials in a reliable and accurately repeatable manner are described. A deformable tube which couples material in a reservoir to a discharge port is pinched by a valve at the same time the reservoir is pressurized. The material is dispensed in correspondence with the amount of reduction of the tube volume by the pinch valve. A simultaneous depressurizing of the material in the reservoir and the opening of the pinch valve enables a suck-back for a crisp cut-off of the material.
