Einrichtung zum Transport von kleinsten Fluessigkeitsmengen und Verfahren zu deren Herstellung

DE 19846958 A UPAB: 20000419 NOVELTY - The apparatus to carry and transport the smallest volumes of fluids has a carrier with hollow micro-structures. The carrier is a monolith body, as far as the hollow micro-structures. DETAILED DESCRIPTION - The carrier is of a thermoplastic material, as a plate (1) with a bonding layer in a composition in a solvent which matches the carrier material. The layer thickness is less than the width and depth dimensions of the hollow micro-structures. The hollow micro-structures are formed by hot embossing under vacuum, in at least one carrier (1). They can also be channels, with sections leading out of the carrier. An INDEPENDENT CLAIM is included for the production of a carrier to transport very small fluid volumes where a bonding layer is applied in a dissolved condition between carrier plates (1), in a layer thickness which is less than the width and depth dimensions of the hollow micro-structures. USE - The system is for the transport of fluids in pica liter volumes in medicine, biotechnology and pharmacology applications. ADVANTAGE - The micro-structures to carry the fluid volumes have an increased shape and cross section accuracy. The carriers are produced economically in mass production
