Now that I’ve finished my biochemistry and microbiology course, I’m no longer performing endless protein assays which require so much pipetting that you leave the lab with your hand seized up in to a crab claw because you’ve been holding a Gilson for two and a half hours. If you study biology, you will no doubt make acquaintances with Gilsons fairly early on in the year. This, my friends, is a Gilson pipette.
They come in a few different sizes and use very fine pipette tips to measure very small amounts of liquid (usually less than a millilitre). They have a dial on the top which you have to turn to set the volume you want to draw up and you have to depress the plunger before you put the tip into the liquid and then release it or you end up sucking stuff in to the barrel.
