Brand® HandyStep® Electronic is a microprocessor-controlled, motorised, positive displacement, stepping pipettor system, comprising hand-held pump unit with rechargeable battery, digital display and keypress operation and a series of accessory reservoir tips allowing single volumes from 1µl to 50ml (depending on the tip selected) to be repeatedly and accurately dispensed.
- Continuous step volume adjustment (within the parameters of the tip)
- Dispensing, automatic (repeat) dispensing or pipetting modes
- Automatic tip recognition (of PD-tips only)
- Independently adjustable aspiration and dispensing speeds
- Compatibility with other common stepper pipette tips (but without tip recognition, tip volume must be manually entered)
- Factory calibrated
- Clear LCD menu readout shows function, step volume and number, speed and battery status, or tip details
- The rechargeable NiMH battery is quickly charged using the dock supplied, and is easily exchanged for a spare battery, if required, saving interruption of work whilst waiting for charging
