After nearly a year on the market, the flexible, accurate Rainin E4 XLS family of electronic pipettes from Mettler Toledo continues to prove its worth by helping users master a wide range of life-science applications worldwide - and helping manufacturers preserve research budgets and keep experienced operators on the job longer with a robust package of hand-saving, accuracy-enhancing features.

The E4 XLS, designed to be the most ergonomic electronic pipette available, offers a comfortable grip, precise balance and a large full-colour screen for easy reading and operation. Designed to enhance speed and prevent user fatigue, the E4’s joystick control and logical menus, available in single channel, multichannel and adjustable spacer formats, simplify switching between functions. This ease-of-use helps experienced operators accomplish more with fewer errors for manufacturing cost-savings in reduced rework. Less impact to the hand’s delicate musculature can translate to fewer repetitive motion injuries and lowered healthcare and labour training costs.

The E4 XLS is also extremely versatile, allowing operators to gain its ergonomic benefits across a wide range of pipetting functions. These include titration, dilution, reverse-mode pipetting and sequential volume programming for complex protocols. A multi-dispense feature automatically calculates how many aliquots can be dispensed from a single pickup so operators quickly ascertain how many samples can be prepared. Autopace simplifies repeat dispensing with one-click dispensing across a plate based on user input, while advanced blowout and automatic dispensing options give users even more control. TrueManual mode is also available for a manual pipetting experience when desired

Embedded radiofrequency identification (RFID) tags enable advanced calibration and inventory management. As part of its robust software package, the E4 XLS is the first electronic pipette that can be upgraded and expanded directly from an operator’s PC, easing maintenance and helping to ensure a long operating life.
