Dispense head VTOI: 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 for a conventional design. High-performance materials make the VTOI suitable for use with aggressive media.
The simple 8-channel dosing system
For increased throughput: Thanks to the width dimension of 9 mm and a valve with 8 outlets, the VTOI is an optimized 8-channel dispense head for microtiter plates. A 96-channel dispense head can now be realized 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 makes it possible: With VTOI you can not only dispense but also aspirate. The minimum dispensing volume is 1 μl. The typical dispensing precision CV is ≤3% for intra-run and ≤5% for tip-to-tip – right down to the microliter range.
A tough performer
All components that come into contact with the media are made exclusively from high-performance materials such as PEI (ULTEM), PPS, FKM, ETFE and high-alloy steel. This means that aggressive media can also be dispensed.
With VTOI, liquids in the smallest µl range can be dispensed and aspirated.
Areas of application:
- Dispensing reagents into microtiter plates
- Aspirating liquids when working with antigens or when culturing cells
The 8-channel dosing system
Thanks to the 9 mm width dimension and a valve with 8 outputs, the VTOI is an optimal 8-channel dispense head for microwell plates – with increased throughput. A 96 dispense head can be realized with only 12 valves – in contrast to the conventional design, 84 valves can be saved. With just a few other components from Festo, you can have a complete, pressure-controlled dispensing system.
Just a few components needed for a complete system
You only need five different basic modules for an 8-channel, pressure-controlled dispensing system:
The pressure and vacuum generator VEAB, a reservoir, the dispense head VTOI, the valve control module VAEM and an appropriate handling system for moving the dispense head.
With these few components you obtain a complete, 8-channel dispensing system for filling microwell plates quickly, easily and cost-effectively.
