Mettler Toledo Rainin Pipet-Lite XLS+ and E4 XLS+ pipettes

Mettler Toledo has released an upgrade of its single- and multichannel Pipet-Lite XLS+ manual and E4 XLS+ electronic pipettes. Now, all pipettes branded XLS+ feature wet seals for smooth operation, corrosion-resistant tip ejectors and liquid ends that can be autoclaved.

With a redesigned liquid end, the Rainin Pipet-lite XLS+ manual pipettes deliver high performance with comfort and control. The ‘stiction-less’ sealing system delivers a plunger action that is smooth from start to finish, allowing for complete pipetting control and ease. The corrosion-resistant plastic tip ejectors, made of PVDF polymer, can be removed with a single-hand motion for easy cleaning. The complete liquid end - shaft, seal assembly/spring and ejector - can be autoclaved for easy sterilisation.

The latest software for the E4 XLS+ electronic pipette is said to make it the most versatile and secure electronic pipette on the market. The Admin mode enhances GLP/GMP compliance by enabling pipette settings, protocols and service alarms to be password-protected. For convenience and security, the pipette menu can be configured (eg, hiding unwanted modes, locking in settings, etc) to be as simple or complex as users wish. Furthermore, multiple custom protocols can be stored and quickly recalled with a simple joystick movement.

Mettler Toledo is also releasing a 1200 µL XLS+ multichannel pipette said to be more hand-friendly and reliable. With a liquid end that weighs 19% less than comparable XLS versions, up to 42% lower pipetting forces and 52% less tip eject force, multichannel pipetting is made easy. By minimising stiction, the sealing system delivers good control for work that requires slow, careful pipetting. The product’s mechanical design assures high performance, including channel-to-channel consistency.
