Tips for Pipetting

  • Use anti-fatigue floor mats if standing for long periods.
  • Sit supported against the backrest of your chair.
  • Sit or stand close to your work at bench cut outs.
  • Adjust your chair to work height rather than jutting out your chin or bending your neck down when working.
  • Elevate your chair rather than reaching up to pipette.
  • Do not twist or rotate your wrist while pipetting.
  • Alternate or use both hands to pipette.
  • Hold the pipetter with a relaxed grip.
  • Use minimal pressure while pipetting.
  • Use light force or two hands to change tips
  • Use low profile tubes, solution containers and waste receptacles.
  • Select a light-weight pipetter sized for your hand.
  • Use pipetters with finger aspirators and thumb dispensers to reduce thumb strain.
  • Use latch-mode or electronic pipetters for repetitive pipetting.
  • Take a 1 to 2 minute break after every 20 minutes of pipetting.
