This page summarizes a variety of microfluidic chips for optical measurements. Several of these chips have different chamber depths within the measurement window allowing to enlarge the dynamic range of the analytical process. Chips for self-filling are included as well as with larger reservoirs enabling easy sample introduction combined with defined sample volume.
Cuvette Chip
Cuvette chip 527 is a chip with eight parallel measurement cavities with three chamber depths.
Cuvette Tank Chip
Cuvette chip 553 is a chip with larger sample uptake interface and measurement cavity with two chamber depths. To avoid a liquid flow after filling the measurement chamber until equilibrium between inlet and outlet filling height is ensured, the chips can be equipped with a venting membrane allowing to dissipate air, but remaining liquid tight.
Cuvette Tank Chip with Incubation Meander
Cuvette chip 576 is a chip with larger sample uptake interface and measurement cavity with two chamber depths and a reaction channel for prefilled reagents. To avoid a liquid flow after filling the measurement chamber until equilibrium between inlet and outlet filling height is ensured, the chips can be equipped with a venting membrane allowing to dissipate air, but remaining liquid tight.
