Fluid-dispensing apparatus with controlled tear-off
Abstract:
Fluid-dispensing apparatus include a fluid-dispensing needle. A gas discharge member is positioned proximate a dispensing end of the needle that is configured to direct a gas towards a fluid tear-off position below the dispensing end of the needle. A controller controls discharge of the gas by the gas discharge member to control dispensing of fluid from the needle. The dispensing control may control an amount of fluid dispensed from the needle and/or tailing off of fluid dispensed from the needle. The amount of fluid dispensed from the needle may be a microliter range volume of a viscous fluid.
