Product description
The BioDeviceLab Weir Filter Microfluidic Chip is designed for efficient, passive filtration and size-selective separation of particles, cells, or debris using precisely engineered weir structures embedded within the microchannel network. The chip guides fluid through parallel channels incorporating repeated weir geometries that retain larger components while allowing smaller species to pass downstream. Fabricated from an optically transparent, lab-grade polymer, the device enables direct visualization of filtration performance and clogging behavior in real time. Its compact footprint and well-defined fluidic routing make it suitable for sample preparation, debris removal, and upstream conditioning of biological or chemical samples prior to downstream analysis.
