PRODUCT DESCRIPTION The FINNPIPETTE COLOUR FIXED VOLUME is a general purpose micropipette for sampling and dispensing accurate amounts of liquids. It operates on an air displacement principle (i.e. an air interface) and uses detachable, disposable tips. FINNPIPETTE COLOUR FIXED VOLUME pipettes cover a volume range of 5-5000 µl.

CALIBRATION All Finnpipettes 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 recalibration (Fig.8) and adjustment for liquids of different temperature and viscosity.
