Chip Analysis Demo-Module (Disposable chip type)

This module demonstrates the most basic process from sample introduction to mixing of a sample with a reagent and detection, by using a chip with Y-shaped internal channels. The sample is introduced to the chip by an ultra-small peristaltic pump and, after metering the volume in accordance to the length of the channels, transported and mixed with the pre-filled reagent by a pair of electro-osmotic pumps together. The flow is controlled by ultra-small valves. The chip is intended to be disposable and can be easily fastened by the plate.

In a reagent loading demo-module, a fixed volume of reagent is sucked from a reagent bottle and injected into a chip by a pen-type syringe pump combined with an ultra-small inert 3-way solenoid valve.

Both demo-modules are small with outer dimensions of 40 x 50 x 125 mm facilitated by our ultra-small components.

• Pumping volume has negative effects on analysis accuracy and precise fluid dispensation.   Through the incorporation of part of the flow path into a sliding structure, this pumping volume is reduced to almost zero.

• Elimination of excess internal volume has reduced cross-contamination.

• Exhibits an impressive increase in operating pressure.

• Utilization as a sample injector is now possible.

• PTFE and PEEK are used as the wetted materials.

Film Manifold (Patent Pending)




   1224 KB / 5.4 MB

Application Example Video>>> 698 KB / 2.5 MB - Ultra-small Solenoid Valve FV Series and Film Manifold with Y-Shaped channel configuration.

The Film Manifold is small, lightweight and made by engraving precise channels in layers of bonded chemically-inert Polyimide (PI) etc. Compared to the current acrylic manifold, the Film Manifold exceeds in chemical inertness and can be significantly smaller.
Furthermore, with a minimum layer thickness of only 75 μm, the Film Manifold has the following
notable characteristics.

1. Bendable.
2. Easy control of channel temperature.
