Excel™ Single- and Multi-channel Electronic Pipettors
- Exceptional Accuracy and Precision
- Simple, Precise Vol Setting
- Fully Motorized Piston Drive
- Multifunctional with Six Operational Modes
- Virtually Eliminates Pipetting Force
- 1-year warranty
Excel™ Electronic Pipettes are multifunctional units with operational modes for standard and reverse pipetting as well as multiple and sequential pipetting, mixing of samples, and serial dilutions. All functions are easily programmed with one hand on the well-positioned display and keypad. A fully motorized piston drive and auto-calibration guarantee excellent accuracy and reproducibility. A removable, rechargeable lithium-ion battery ensures many hours of performance between charges.
The body of the pipette has been designed to fit comfortably in the right or left hand. Along with being lightweight, the unit is also well-balanced. The plunger button, located on the back side of the instrument, requires just a small movement of the index finger to activate, reducing the risk of Repetitive Strain Injuries (RSI). The tip ejector slides easily with slight pressure from the thumb.
A small, rechargeable, lithium-ion battery powers the Excel™. A complete charge is achieved in just eight hours and last for 2,000 pipetting cycles. To ensure that a fresh battery is always available, a stand-alone charger and extra batteries are available. Also available is a 3-position linear stand for up to three single or multichannel pipettes and a carousel stand for up to six single or multichannel pipettes.
