Product Description The DIGITAL PIPETTE is a continuously adjustable, general purpose micropipette for sampling and dispensing accurate liquid volumes It operates on an air displacement principle and uses detachable, disposable tips. The adjusted delivery volume is displayed digitally on a numeric readout window on the handle. The seven different models of Digital Pipettes covers a volume range from 0.5ul to 5ml. Calibration All DIGITAL PIPETTES are factory calibrated and adjusted to give the volumes as specified with distilled or deionized water. Normally, the pipettes do not need adjustment, but they are constructed to permit readjustment for liquids of different temperature and viscosity. CHECKING THE CALIBRATION The pipette is checked with the maximum volume (nominal volume) and with the minimum volume A new tip is first prewetted 3-5 times and a series of ten pipettings are done with both volumes. A pipette is always adjusted for delivery (Ex) of the selected volume. Measuring volumes taken from balance is not allowed. If the calculated results are in the limits the calibration of the pipette is correct. (Please read the manual before use and follow the instructions in the manual.)
