The Robbins Automatic Serum Dispenser is a precision multichannel dispenser for adding microliter volumes of serum to all wells of a typing tray simultaneously. It consists of a fixed array of glass syringes whose plungers move up and down in unison to fill and dispense serum into the tray.
Operation is completely automatic.
After selecting the syringe fill and dispense volumes and number of syringe wash cycles through the display on the front of the unit, a rack containing Robbins serum tubes is placed on the platform. Upon depressing the up button, the motorized platform lifts the rack to the syringe needles, the syringes fill to the volume selected and the platform returns to its original, down position. To fill trays, a single typing tray is placed on the platform and the dispense operation activated using the Dispense button or convenient foot switch. The platform raises to the needles and the volume of serum selected is dispensed into the wells with the volume of serum remaining in the syringes updated on the display. After filling the desired number of trays, serum remaining in the syringes is returned to the serum tubes by placing the rack back onto the platform and pressing the Empty button.
