Automate your multichannel pipettes!

Multichannel pipettes are invaluable when working with multiwell plates. However, prolonged and repetitive pipetting sessions bear the risk of strain and fatigue, often resulting in repetitive strain injuries (RSI) and less reproducible results.

VIAFLO ASSIST together with INTEGRA’s VIAFLO II electronic pipettes form the perfect symbiosis to prevent users from RSI and to significantly increase the reproducibility of prolonged pipetting protocols such as serial dilutions, plate filling and reagent addition.

By mounting a VIAFLO II electronic pipette on the VIAFLO ASSIST, the pipette’s protocols can be carried out fully automatically.

Overview (also click on tabs below for further information)

  Touch wheel interface
A full color screen and a proven touch wheel interface offer quick and comprehensible menu navigation. Simply by moving a finger over the touch wheel, menus and settings can be accessed.
 

  VIAFLO ASSIST
Smart pipette adapter
Any VIAFLO II multichannel pipette can be mounted to the smart pipette adapter. Pipettes are available as 8-, 12-, and 16-channel models, covering a volume range of 0.5 -1250 µl.
  Bluetooth communication
The pipette and VIAFLO ASSIST are connected via Bluetooth, supporting convenient wireless connectivity.
   
Plate compatibility
Use 6-well to 384-well plates in either landscape or portrait orientation.
  Compact size
The instrument’s footprint is small and it is light weight. This makes it easy to relocate it anytime and use it in a laminar flow cabinet.
     
    Choice of reservoirs
Accommodates reagent reservoirs of three different volumes: 10 ml, 25 ml and 100 ml.
 

Automated Multichannel Pipetting

Improved ergonomics
No matter how light and well balanced a pipette is, prolonged pipetting tasks remain physically and mentally challenging. While some steps always need to be performed manually, many other steps can be automated. To prevent RSI caused by extensive repetitive motions, manual pipetting should be minimized. VIAFLO ASSIST lets you switch between the manual and automated pipetting tasks on the fly, relieving you of much of the pipetting burden.
VIAFLO ASSIST

Consistent pipetting
The benefits of automating a pipetting procedure are manifold. Next to optimizing ergonomics, it increases the reproducibility of pipetting. The major source of problems in pipetting performance are human errors. Typical parameters influencing the performance are tip immersion depth and pipetting angle. The automated pipetting capability of VIAFLO ASSIST ensures these parameters are always the same, resulting in an increased reproducibility. Also, VIAFLO ASSIST makes no pipetting mistakes!

Versatility

Smart pipette adapter
The pipette adapter of VIAFLO ASSIST allows the use of all VIAFLO II multichannel pipettes. The width of the adapter can be adjusted so that 8-, 12-, and 16-channel pipettes can fit. The pipettes cover a volume range of 0.5 – 1250 µl.

Plate compatibility
Plates of 6-wells to 384-wells can be used. The plate sledge accommodates the plates either in portrait or landscape orientation.

User Interface

VIAFLO ASSIST

Navigation
Protocol setup and selection is done using the pipette’s intuitive user interface. It is based on the popular Touch Wheel and allows extremely fast menu navigation and volume adjustments. Simply by moving a finger over the touch wheel, menus and settings can be accessed.

Choosing a protocol
Three predefined protocols allow a quick start: Serial Dilution, Repeat Dispense and Variable Dispense. For more elaborate pipetting routines, custom programs can be created in an easy step by step setup.

GripTip System

VIAFLO ASSIST

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

 

A shoulder provides a positive stop to prevent over-tightening of the tip. It can only be attached up to that point and no further, ensuring that all tips are at the same height. That means, the tip is either on or off, but nothing in between.

 

GripTip pipette tips snap on
Do your pipette tips ever loosen, leak or fall off? This is a common issue in laboratories, caused by the use of standard pipette tips. Such tips require “hammering on” and immediately start moving back to their original shape, away from the tip cone. This can cause leaking, unaligned tips and even pipet tips that completely fall off the pipette!

All of this will never happen again 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!

Serial Dilutions (also click on tabs below for further information)

Serial dilution

(Click on image to enlarge)

Serial dilutions can be tedious due to the many mixing steps that are required. VIAFLO ASSIST carries out your serial dilution protocols automatically. Simply define the number of mixing cycles, speed and mix volume.

Serial dilutions are often carried out with the plate in portrait orientation. This allows more samples to be diluted. VIAFLO ASSIST allows working in landscape and portrait format.

The concentrated sample can be drawn from a reagent reservoir, a PCR tube strip and the plate itself (e.g. First column). In addition, the sample can also be aspirated with the pipette from an external source before placing it on the VIAFLO ASSIST and starting the protocol.

Plate Fillings

Plate Filling

(Click on image to enlarge)

Filling multiple plates might not be a difficult task but is strenuous nonetheless. In order to improve pipetting ergonomics, manual pipetting should be minimized.

VIAFLO ASSIST helps you to fill microplates without risking repetitive strain injury.

Reagent Additions

Reagent Addition

(Click on image to enlarge)

Draw reagent from the reagent reservoir, a PCR tube strip , the plate itself or an external source to add it to the target plate.

An optional mixing step helps to achieve a homogenous distribution of the sample.

For a precise liquid transfer and to make sure that no remaining liquid clings to the tip end, performing a touch off is common practice. VIAFLO ASSIST allows both a touch off on the side wall of the well or inside the liquid.
