Pipetting-practice card

With the pipetting practice card you can repeatedly practice and control the handling of a microliter pipette without much preparation. Simply place the card in front of you, adjust the pipette to the volume shown under the circles and pipette a liquid into the center of the circle. If the pipette is operated correctly, the drop will not overflow the black edge mark, but will fill the circle completely. The postcard sized card is large enough to be convenient to use and the coating allows for washing, drying and repeated use.
