PHOTONIS Glass Capillary Arrays (GCAs) consist of millions of precision glass capillary tubes fused together to produce a uniform and mechanically rigid structure. They can be supplied as circular or square thin plates and offer sieve-like filtration with a positive particle size cut-off. GCAs are strong, self-supporting devices with exceptional thermal and chemical stability; they can be manufactured to withstand temperatures greater than 500 °C for application in severe environments.
