VIAFLO ASSIST - Your personal pipetting assistant

publication date: Jan 15, 2014
author/source: INTEGRA Biosciences AG

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 increase the reproducibility of prolonged pipetting protocols such as serial dilutions, plate filling and reagent addition significantly.

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


Main Features





Serial Dilutions

Serial Dilutions

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 Fillings

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 Additions

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.
