How to use


①Set the aspiration

volume using the aspiration-volume-setting dial.
Note: DO NOT set volume exceeding the volume of serological pipette.

②Attach the serological pipette to the Peggy nozzle.

※You can use 5 mL and 10 mL plastic serological pipettes from various manufacturers.

③Push the aspiration button slowly to aspirate the sample. After aspiration, slowly lift the Peggy out of the test tube.

  • If the aspiration button is pushed in before aspirating a sample, it results in insufficient aspiration. Make sure the aspiration button is in the original position by pushing dispensing button.
  • The movable range of the aspiration button is variable depending on the setting. The smaller the set volume is, the less the movable range is. Do not push in the aspiration button forcibly when it stops. It enables the protection system to unlock and change the dial setting.


①Set the dispensing volume using the dispensing-volume-setting dial.

②Push the dispensing button one by one. Hold down the dispensing button until the solution no longer comes out of the tip. Each time the button is pushed, the set volume is dispensed.

  • When you dispensing repeatedly, make sure the button comes back to the top position every time dispensing is completed.
  • When you dispensing higher volume, press the dispensing button slowly.
  • The aspiration button comes back to the original position as you push the dispensing button. Release your fingers from the aspiration button while operating the dispensing button.
