Matrix Impact2 12 Channel Electronic Pipette 50-250 l Charger sold separatelyImpact2 multichannel pipettes allow you to utilize the power of electronic pipetting in microplate formats. In addition to an ergonomic design, Impact2 pipettes feature step-based programming that allows you to perform pipetting routines that would either be cumbersome or even impossible with manual pipettors. What used to take many motions of the thumb and manual adjustment of a volume knob can now be accomplished with the light touch of a button. Lightweight, ergonomic design increases comfort and reduced risk of repetitive stress injuries. Trigger-based operation and tip ejection eliminates use of thumb; reduces strain when ejecting tips. Step -based programming makes it logical, intuitive and easy to create programs. Enables the pipettor to perform all the tasks you might do with a manual pipettoronly faster and with less effortas well as functions such as serial dilutions across a microplate. On-board memory saves six programs (up to 40 steps each) allowing you to spend more time pipetting, less time programming. Large volume capacity of 1250L per tip allows you to fill an entire microplate with up to 100L per well from a single aspiration. Advanced battery technology allows days of work between charges, no memory effect. Stepper motor technology and error correction software ensure accurate and precise pipetting, even when performing incremental dispensing or when operating at top or bottom of a pipettors volume range. Pipette can be used while plugged in resulting in no downtime during recharging.
