Each device fits comfortably in either the left or right hand, and allows a 360 egree rotating manifold. Each unique electronic pipettor is as easy to use as a mechanical one. Pipettors are equipped with only two buttons for activation and selection. A push button sets the volume via left or right selection, and a Mode button provides selection from 5 essential pipetting modes and functions. This intuitive interface offers Pipet, Repetitive, Mix, Reverse, and Custom Mode, into which users can quickly and easily create specific protocols thanks to VWR Protocol Builder Software. Choose from a wide range of electronic pipettors covering volumes from 0.5µL to 1200µL, in both single channel and multi channel versions. All devices are engineered to optimize pipetting tasks. If the VWR Electronic Pipettor is discharged yet requires use, simply plug in and it will charge while pipetting, without compromising performance. Each VWR Electronic Pipettor includes a two-year warranty. Pipettors are supplied with one Lithium-Ion battery, a USB power supply (5V), a tip ejector extension (for 10µL models only), a certificate of conformity, a lubricant (except for 10µL and multi channel models), and a Quick start guide. Accessory stands are sold separately.
