VIAFLO II electronic pipettes – never loose a tip again!

Solving many issues of traditional manual pipetting, VIAFLO II electronic pipettes excel in terms of ergonomics, ease of use and productivity.

Viaflo Multichannel Pipette

 

Operational Comfort
The ultra lightweight, well balanced design of the VIAFLO II pipettes features unsurpassed multichannel pipetting ergonomics, even during prolonged pipetting sessions.

GripTip pipette tips that will not fall off
The pipettes and the unique GripTips together form an integral pipetting system. GripTips snap into place with minimal tip loading effort, providing a secure connection.

Easy operation
The color screen together with the intuitive to navigate touch wheel user interface promote overall ease of use.

GripTip System (also click on tabs below for further information)

GripTip Pipette tips System

The rim of the GripTips will snap over the
Multi-Lobes, attaching firmly. As a result,
GripTips will never accidently fall off, even
after several touch-offs
.

 

A shoulder provides a positive stop to prevent over-tightening of the tip. The pipette tip cannot be advanced beyond the positive stop ensuring all tips are at the same height, thus
increasing the precision when touching off. That means, the tip is either on or off, but nothing in between. Hammering the pipette
into the tips to make sure they attach correctly is no longer required.

 

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 II pipettes. 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!

Touch Wheel Interface

Convenient operation and navigation

The Touch Wheel is a quick and ergonomic way to modify pipetting parameters. Instead of repeatedly pushing buttons or twisting fingers to modify volumes, you simply slide your finger over the wheel.

The Touch Wheel enables you to browse through menus, change pipetting volumes and speeds or other settings.

Full Color Screen

Easy to read display

VIAFLO pipettes feature full text menus, which makes it especially easy to operate the pipette. Everything you need to know is displayed clearly
on the screen. The entire menu structure is available in English, French, German, Chinese or Japanese.

Various Pipetting Modes

Immediately productive

VIAFLO electronic pipettes are easier to operate than manual pipettes and let you get started quickly. The VIAFLO pipettes feature 10 preset pipetting programs, for which only a few parameters such as volume and speed need to be defined.

  • Pipet
  • Repeat Dispense
  • Sample Dilute
  • Pipet/Mix
  • Manual Pipet
  • Reverse Pipet
  • Variable Dispense
  • Variable Aspirate
  • Sample Dilute/Mix
  • Serial Dilution

Customized pipetting programs

For more elaborate pipetting protocols, up to 40 user defined custom programs can be created. The custom program is a step-based setup queuing liquid handling steps such as aspirate, dispense, mix and more.

VIALINK Software

Convenient pipette and program management

VIAFLO pipettes can also be connected to a computer via the serial communication / charging stand (4211). With the free to use pipette management software VIALINK, custom programs can be created on the computer and then be transferred onto VIAFLO pipettes.

For laboratories with many users or power users with many pipetting protocols, all custom programs can be stored and backed up in a library on the computer. For further information visit our VIALINK webpage.

Selected pipetting modes of VIAFLO II pipettes

Repeat Dispense

The repeat dispense mode allows dispensing multiple aliquots of the same volume without refilling the tips after each dispense for fast microplate filling and processing.

To increase the accuracy and precision of the dispenses, a first and last dispense can be defined, which are discarded back to the source or waste.

Manual Pipet

The manual pipet mode gives a user full control over the pipetting cycle. Only as long as the RUN button is pressed, the pipette aspirates or dispenses. The speed and a maximal volume can be set.

This mode can be used to:

  • Measure the volume in a tube or plate
  • Perform titrations
  • Carefully aspirate supernatant without disturbing the pellet

Sample Dilute

This mode enables the aspiration of two different liquids separated by an air gap followed by a dispense of the tip content.

Typically this mode is used to dilute a concentrated sample at which the diluent is aspirated first, followed by the air gap and then the sample. This way the diluent chases the concentrated sample, ensuring no residual sample remains in the tips.

Reverse Pipet

Using this mode a larger volume is aspirated than the actual dispense, leaving a last dispense that is discarded. The function of this mode is equal to the reverse pipetting technique conducted with manual pipettes.

The reverse pipetting technique is used to pipette viscous and volatile liquids and can also improve pipetting results at very low volumes.

Variable Dispense

Aspirate once and dispense multiple differing volumes. Variable Dispense mode eliminates the need to adjust volumes between each dispense.
