Pipetting Robot For Full Workflow Automation

Product story

Frees you from routine pipetting and provides excellent results

Multichannel pipettes increase throughput in today’s laboratories. However, prolonged manual pipetting takes up precious time and can lead to repetitive strain injuries. In addition, ever-decreasing sample sizes have made it increasingly difficult to pipette without errors.

INTEGRA has developed the ASSIST PLUS pipetting robot to streamline routine pipetting tasks at an affordable price. Using INTEGRA electronic multichannel pipettes, the system automates pipetting tasks, eliminates physical strain and ensures superior reproducibility and error free pipetting.

How it Works

How it works

Simply mount an INTEGRA VIAFLO or VOYAGER electronic pipette onto the ASSIST PLUS pipette holder, choose a pipetting protocol, add a tip rack and your labware. Press RUN and ASSIST PLUS will automatically carry out the pipetting task.

  • Overview

    ASSIST PLUS pipetting robot, with key features labelled.

    1) Pipette adapter: accommodates all INTEGRA multichannel pipettes - with fixed and adjustable tip spacing.
    2) User Interface: program setup and selection is done using the pipette’s intuitive user interface.
    3) Deck: three work positions are available to accommodate reagent reservoirs, tube racks and plates.
    4) and 5) Automatic tip change: two dedicated postions for automatic tip loading and tip ejection.

  • Excellent results

    ASSIST PLUS ensures:

    • optimal tip immersion depths
    • consistent pipetting angle
    • controlled pipetting speeds
    • precise tip positioning in wells
    • no pipetting mistakes are made
    • strict adherence to pipetting programs

    This leads to superior pipetting results and work flow consistency, while also eliminating human errors such as skipping rows. 

  • Versatility

    Smart Pipette Adapter

    The pipette adapter of ASSIST PLUS allows the use of all VIAFLO and VOYAGER multichannel pipettes. Pipettes range from 4 to 16 channels and cover a volume range of 0.5 to 1250 μl to allow optimal adaptation to many different applications.

    Labware compatibility

    ASSIST PLUS can accommodate numerous labware types, from tubes to 384-well plates in landscape or portrait orientation. INTEGRA multichannel reservoirs, which are available in 10, 25 and 100 ml sizes offer exceptionally low dead volumes. For larger storage volumes, INTEGRA’s automation-friendly reservoirs can be used.

  • Setting up pipetting tasks

    Directly on the pipette

    Protocol setup and selection is done using the pipette’s intuitive user interface. The Touch Wheel allows extremely fast menu navigation and volume adjustments. Simply choose a predefined program and adapt the default settings to your requirements. 

    Using a computer

    The VIALAB software offers a simple and intuitive graphical user interface, allowing you to create protocols with a few clicks, without extensive programming knowledge.

    VIALINK Pipette Management Software offers advanced users the ultimate freedom of defining pipetting programs step by step.

  • GripTips

    GripTip pipette tips snap into place with minimal tip loading effort resulting in superior accuracy and precision results.

    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!

    1) Lobes
    2) O-Ring Seal
    3) Rim snaps over the Lobes
    4) Shoulder

    The rim (3) of the GripTips will snap over the Multi-Lobes (1), attaching firmly. As a result, GripTips will never accidently fall off.

    A shoulder (4) 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.

    Wish you had been there when I was working

    "I'm retired (78). Had to leave my beloved research position at the VA because my right elbow and thumb could no longer handle the thousands of pipettings per day and return to boring clinical work."

Uses and Applications

Overview Applications Stories


Serial dilutions
Serial dilutions

Repeated dilution steps with optimal pipetting heights, controlled mixing speeds and optional tip change

Performing serial dilutions by hand is a tedious and error prone task, but not with the ASSIST PLUS. It never skips rows, and ensures critical parameters – such as pipetting heights and mixing speeds – remain consistent for excellent pipetting results. If required, tips can be exchanged after every transfer to minimize the risk of carryover.

Pipetting between different plate / tube formats

Reformatting samples – e.g. from tubes into plates – is time consuming and prone to transfer errors. ASSIST PLUS reformats your samples automatically, taking full advantage of the VOYAGER pipette's adjustable tip spacing to process tubes and plates up to 12 times faster than using a single channel pipette.
