    2-10 Ergonomic safety The HP D300 Digital Dispenser typically requires a single manual pipetting operation for each dispensed compound. In most situations, using the HP dispenser in the intended manner decreases the frequency of shoulder, arm, and wrist motions and so decreases the stress on these joints.

  • Page 10: Clean The Dispenser

    As with any lab instrument, it is a best practice to routinely clean areas of the Dispenser that come into contact with chemicals. Turn off the dispenser as instructed in the ―Turn off the HP D300 Digital Dispenser‖ section of this document.

  • Page 11: Get Started

    Get started The HP D300 Digital Dispenser runs on standard AC power, either 120V or 230V, depending on the Dispenser version. HP Product Number CV079A runs on 120V and CV080A runs on 230V. The Product Number and the voltage requirement is shown on the label on the rear of the Dispenser.

  • Page 26 WARNING: For multiplate configurations, the D300 software first minimizes the use of dispenseheads, so that fluids which are used on multiple plates are dispensed into all of those plates as long as the total dispense volume for that fluid does not exceed 10uL. This dispensehead conservation can result in a non-intuitive plate loading order.
