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. VIAFLO ASSIST together with INTEGRA’s VIAFLO II electronic pipettes form the perfect symbiosis to prevent users from repetitive strain injuries and significantly increase the reproducibility of prolonged pipetting protocols. Simply mount a VIAFLO II electronic pipette onto the VIAFLO ASSIST to start automated pipetting.
How it works
1) Set up VIAFLO ASSIST. Based on your application, choose an 8-, 12- or 16-channel VIAFLO II pipette and click it into the smart pipette adapter of the VIAFLO ASSIST. Load your multiwell plate and the sample container.
2) Select a pipetting protocol. For a quick set up, choose between three predefined pipetting protocols. For more elaborate pipetting needs, custom programs can be created. VIAFLO ASSIST will then obtain the protocol via Bluetooth from the VIAFLO II electronic pipette.
3) Execute the pipetting protocol. Press the VIAFLO ASSIST start button to initiate the fully automated processing of the selected pipetting protocol.
Labware compatibility
You can use plates from 6-wells to 384-wells and work with them in portrait or landscape orientation. Samples can be aspirated from a 10 ml, 25 ml or 100 ml reagent reservoir, strip tubes, a multiwell plate or an external source. For perfect pipetting and superior accuracy use VIAFLO II electronic pipettes together with INTEGRA’s wide range of GripTips.
Better pipetting results
The major sources of problems in pipetting performance are human pipetting errors. The tip immersion depth and pipetting angle might differ slightly from column to column even within the same plate. Both factors influence pipetting performance and can lead to ambiguous test results. Automating the pipetting procedure with VIAFLO ASSIST leads to reproducible results and eliminates errors.
Possible applications
- Serial dilutions - Carry out serial dilutions in portrait and landscape format. Transferring and mixing are done automatically.
- Plate fillings - Save time filling 96-well plates in portrait mode using a 12-channel pipette or filling a 384-well plate in one pass using a 16-channel pipette!
- Reagent additions - Small volumes can be aspirated from PCR strip tubes. Alternatively, different reagent reservoirs can be used.
