VIAFLO II electronic pipettes together with INTEGRA’s wide range of GripTips form a perfect pipetting system. GripTips snap into place with minimal tip loading effort, providing a secure connection. GripTips never fall off and are always perfectly aligned, resulting in superior accuracy and precision results.

The color screen together with the easy to navigate touch wheel user interface promote ease of set up and operation. All VIAFLO II pipettes offer a choice of predefined pipetting modes covering typical applications as well as custom multi-step programs for specific tasks.

GripTips snap on

Do your pipette tips ever loosen, leak or fall off? This is a common issue in laboratories, caused by the use of universal pipette tips. Such tips require “hammering on” which stretches the shape of the pipette tip rim. The stretched pipette tip rim immediately starts moving back to its original shape, away from the tip cone. This can cause leaking, misaligned tips and even pipette tips that completely fall off the pipette!

This will never happen with any VIAFLO II electronic pipette / GripTip combination. Featuring a low attachment force and a low ejection force, GripTips effortlessly snap onto the tip fittings and are easily ejected. Also, GripTips feature a high lateral resistance once attached to the VIAFLO IIpipettes. This means GripTips are always firmly attached and perfectly aligned, regardless of how many side well touch offs are performed. You no longer have to hammer your pipette tips on or worry about pipette tips falling off!

Versatile user interface

A color screen and proven touch wheel interface offer quick and comprehensive menu navigation. Simply by moving a finger over the touch wheel, menus and settings can be accessed. All menus are spelled out on the clear to read screen making memorizing abbreviations unnecessary.

A choice of ten predefined pipetting model provides users with convenient solutions for the most common liquid handling tasks. Standard pipetting routines, such as repeat dispensing or serial dilutions can be executed with minimal setup time.

For more elaborate pipetting routines, up to 40 personalized custom programs can be created and saved. Custom programs can contain up to 98 individual steps based upon the following basic operations: Aspirate, Dispense, Mix, Purge and Prompt.Ergonomic design
