Dispense head VTOI

Dispense head VTOI for efficient control

The dispense head VTOI significantly increases your throughput, while at the same time reducing the number of valves you need. For a 96-channel dispense head you need just 12 valves, 84 fewer than with a conventional design. High-performance materials make VTOI suitable for use with aggressive media.

The simple 8-channel dosing system
Thanks to the 9 mm grid dimension and a valve with 8 outputs, the VTOI is an optimal 8-channel dispense head for microwell plates – with increased throughput. A 96-channel dispense head can now be realised with only 12 valves. With just a few other components from Festo, you can have a complete, pressure-controlled dispensing system.

Highly precise pipetting and dispensing
The vacuum function not only enables you to use the VTOI for dispensing, but also for aspirating. The minimum dispensing volume is 1 μl. The typical dispensing precision CV is ≤3% for intra-run and ≤5% for tip-to-tip, down to the microlitre range.

A tough performer
Only high-performance materials such as PEI (ULTEM), PPS, FKM, ETFE and high-alloy steel come into contact with the media. This means that aggressive media can also be dispensed.

With VTOI, liquids in the smallest µl range can be dispensed and aspirated.

Applications:

• Dispensing reagents into microwell plates
• Aspirating liquids when working with antigens or during cell cultivation

The 8-channel dosing system

Thanks to the 9 mm grid dimension and a valve with 8 outputs, the VTOI is an optimal 8-channel dispense head for microwell plates – with increased throughput. A 96-channel dispense head can now be realised with only 12 valves, saving 84 valves when compared with a conventional design With just a few other components from Festo, you can have a complete, pressure-controlled dispensing system.

A complete system with just a few components

You only need five different building blocks for an 8-channel, pressure-controlled dispensing system:
The pressure and vacuum generator PGVA, a reservoir, the dispense head VTOI, the valve control module VAEM and a suitable handling system for moving the dispense head.
With these few components, you get a complete, 8-channel dispensing system that allows you to fill microwell plates quickly, easily and cost-effectively.
