  1. Hello,
    Variable volume adjustable hand pipetters are very useful in any laboratory where multiple volumes are needed. Just turning the knob to the desired volume gets the job done quickly and accurately. This is excellent for switching to different volumes for adding different substances to the same test tube, such as the reagent and blood used in a Reticulocyte count.
