title: CONSTANT VOLUME, SELF-FILLING NANOLITER PIPETTE: CONSTRUCTION AND CALIBRATION.
abstract: Pipettes with volumes ranging from less than one nanoliter to 200 nanoliters can be constructed by means of a simple mechanical system and calibrated by radioisotope and fluorescence techniques. Biological fluids can be transferred with a repeatability of 1 percent by this self-filling pipette of constant volume.
