Versatile Viafill offers three modes of operation

Can be used as a bulk reagent dispenser, multichannel pipettor and plate washer

Visifill can be used as a bulk reagent dispenser, multichannel pipettor and plate washer

Integra has added the Viafill, which delivers high performance bulk reagent dispensing, multichannel pipetting and microplate washing capabilities from a single multipurpose instrument, to its product portfolio.

The Swiss supplier of laboratory tools for liquid handling, media preparation, sterilisation and cell cultivation, offers a choice of tubing sets for the Viafill to allow the user to switch between these three modes of operation.

When used as a bulk reagent dispenser the Viafill uses a choice of dispensing tube sets to enable accurate and rapid reagent addition in volumes ranging from 0.5┬Ál to 10ml into 6-, 12-, 24-, 48-, 96-, 384- and 1536-well plates. A unique 16-channel tubing set is available to enable the productive filling of 384- and 1536-well plates.

The addition of a plate stacker module allows unattended operation further increasing reagent dispensing productivity and throughput.

With GripTip kits the Viafill can be used as an automated multichannel pipettor. In this mode, reagents are aspirated from a reagent reservoir directly into the pipette tips instead of being pumped through the entire tubing set. This enables the instrument to perform more complex applications like serial dilutions saving precious reagents because there is no need to pump them through the entire tubing set.

GripTip kits also allow users quickly to fill a few plates without having to wash and sterilise the entire dispensing tubing sets.

The Viafill can be also converted into a plate washer/aspirator by attaching the wash module. This allows users to aspirate supernatants from well plates into an external container for collection or disposal, and at the same time enables users to rinse the plates with a wash solution. The movement of the aspiration tube can be set to either a linear or circular path. Eight- or 16-channel wash tubing sets are available to accommodate 96 or 384 well plates.
