This is a improvised pipette for DIY biology using a drinking straw. Use this to pipette small volumes until you get a real micropipette!

See it in action here: http://youtu.be/Q6cFps88G9M


  1. Print StrawPipette.stl
  2. If necessary, clean up hole so straw slides in easily. The straw should stay in snugly, but shouldn't crush the straw.
  3. If required, sterilise some drinking straws.
  4. Insert straw and use pipette:
    i. Insert into liquid, cover top of straw with thumb.
    ii. hold thumb on straw while transferring liquid.
    iii. release thumb to dispense liquid.
  5. Change straw when you would change a micropipette tip.


It operates in the range 200μL to 1000μL, and with practice you should be able to reliably dispense liquid in 100μL increments.

Volume dispensed = π radius of straw^2 depth into liquid
