A range of chips made by bonding precision-moulded plastic plates is available, offering competitive prices in mass production quantities. The minimum channel size is 50μm square. Channel pattern can be freely designed. A choice of material COC (cyclic olefin copolymer), PMMA (acrylic) and PS (polystyrene) is available. These materials all exhibit excellent optical characteristics. Bonding is achieved through the use of a special technique that does not use adhesive, so the channels are absolutely contamination-free. The bonded surface is beautifully finished, giving outstanding transparency. As the channel size is minimized, the quantity of sample or reagent used can be reduced. Furthermore, since precision-moulded plastic plates are used and the price can be decreased in mass-production, these chips are suitable for use as disposable testing chips. Bonding of machined plates is also possible for prototype chips without using moulding tools. Consideration of other materials is possible, please feel free to inquire.
