All piston movements are controlled by the onboard microprocessor, which moves the piston the set distance at the set speed, regardless of user. The advanced stepper motor has 4,000 discrete steps, providing highly precise liquid measurements. At the end of each pipetting cycle the E4 XLS adjustable spacer re-calibrates itself by resetting the zero point.
Continuously-variable spacing allows nozzle spacing between 9-14 mm on 8-channel models and 9-19 mm on 6-channel models, suitable for pickup from 96-well plates and dispensing to 24-well plates or tubes, or vice versa. Smooth one-hand adjustment enables on-the-fly changing after aspiration and before dispensing. Spacing marks give a quick visual aid, or set the adjustable detent for repeatable spacing without looking.
Patented LTS tip and nozzle design provides exceptionally easy multichannel tip mounting. Perfect sealing – first time, every time – without rocking or hand-tightening. Try it – you’ll be amazed how easy it is to get absolutely consistent sample pickup across all channels.
Multi-dispense takes the drudgery out of repetitive pipetting by calculating how many aliquots can be dispensed from a single pickup. Autopace simplifies repeat dispensing – click the joystick once and repeat dispense across a plate.
No manual required! The E4’s large color screen, carousel navigation and joystick control make operation easy and highly intuitive. From straightforward pipetting to complex applications, this tool can do it all. Its long-life battery gives a day’s worth of pipetting with minimal charging and will last for thousands of recharges.
Reduce compliance risks! Onboard service data is extremely secure and quick to access. Avoid calibration compliance errors by password protecting access to service interval alarms. Minimize pipetting SOP deviations by locking protocol settings.
The E4s’ Admin Mode enables you configure the pipette any way you want. For convenience or security, remove unwanted modes or lock in settings. Create personalized setting profiles to “re-set” your pipette to a preferred configuration.
Store multiple custom protocols in the on-board memory. Simultaneously review and select your protocols with a simple movement of the joystick. No more re-entering preferred protocols over and over again!
Purify biomolecules from proteins to oligonucleotides to chromatin using E4 XLS adjustable spacer pipettes and Rainin’s PureSpeed™ tips. Unite rapid and gentle processing of multiple samples with high elution concentration for an unbeatable combination! All E4 have the PureSpeed functionality pre-installed.
