Mettler Toledo Single Channel Electronic Pipettes

The cushioned joystick control of the E4 XLS+ single channel electronic pipette makes it easy to configure and run protocols. Get consistent volume and identical speed for every step. Measure precise volumes in Manual mode and dispense multiple aliquots in Multi-dispense. Automate cycle counting so you can concentrate on other details, and relieve your thumb with options to auto-mix or auto-dispense. It's easy to store settings so you can duplicate an assay later.

Ergonomic Pipette

Lightweight and designed for use with either hand, the E4 XLS+ single-channel electronic pipette fits like a glove and is extraordinarily well balanced while pipetting. The carefully shaped fingerhook enables a relaxed grip. Extremely light operating forces and a silicone shock absorber built in to the tip ejector make the E4 a pleasure to work with. On LTS-equipped models, tip ejection force is just 0.6 kg.

Compliant Pipette

To accommodate GLP/GMP compliance, the E4 makes it possible to password-protect pipette settings, protocols and service alarms. Service records, cycles and status data are completely tamper proof.

A Feature-Rich Electronic Pipette

Increase your productivity and speed your workflow with Rainin's most fully featured and easy-to-use single channel electronic pipette. Password protected pipette settings include protocols and service alarms for GLP/GMP compliance. GLP data, such as service records, cycles and status data are completely tamper proof.

Accurate and Precise

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+ single channel electronic pipette re-calibrates itself by resetting the zero point.


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.

Highly Configurable

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.

PureSpeed on Board

Purify biomolecules from proteins to oligonucleotides to chromatin using E4 XLS+ single channel electronic pipettes and Rainin’s PureSpeed™ tips.

GLP/GMP Secure

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.

Save your Protocols!

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!

PureSpeed on Board

Unite rapid and gentle processing of multiple samples with high elution concentration for an unbeatable combination! All E4 have the PureSpeed functionality pre-installed.
