The labopettor pipettes are characterized by highest precision, regardless of the medium. Through the principle of direct liquid displacement almost no residual wetting remains in the unit. Also, the pipetting of strong gaseous liquids with high vapor pressure, highly viscous media and media of extremely high density is unproblematic. Each unit is supplied with an individual serial number and weighing report . It also covers the routine range from 1 to 5000 ul completely. Thus, the pipetting can be exactly reproducible.
