The Metrics Golden Standard Chip Fluidic 1575 features 8 individual functional units with Mini Luer interfaces, each designed for exact measuring of volumes. Each design features two main channels, connected by a "leakage channel”. The leakage channels come in two distinct lengths. The cross-section of the leakage channels is rectangular and varies between designs.
