DE 102007041071 A1 UPAB: 20090403 NOVELTY - The fluid reception device for supplying the fluid on sample carrier (8), comprises recesses (9), whose base has holes, which are formed so that the capillary pressure in the respective hole is greater than the pressure produced through the fluid in the respective recess. The hole has a diameter of 50 mu m and a length of 1200 mu m and/or 200 mu m. The device represents a multi-corrugated plate, which has 96, 384 or 1536 corrugations and represents a micro-corrugated plate (4). The corrugated base of the multi-corrugated plate has thin glass capillaries as the hole. DETAILED DESCRIPTION - The fluid reception device for supplying the fluid on sample carrier, comprises recesses (9), whose base has holes, which are formed so that the capillary pressure in the respective hole is greater than the pressure produced through the fluid in the respective recess. The hole has a diameter of 50 mu m and a length of 1200 mu m and/or 200 mu m. The device represents a multi-corrugated plate, which has 96, 384 or 1536 corrugations and represents a micro-corrugated plate (4). The corrugated base of the multi-corrugated plate has thin glass capillaries as the hole. The corrugated base of the multi-corrugated plate is formed from a glass plate or an adhesive or laminated plastic foil. The multi-corrugated plate is sealed towards the top through a flexible membrane. INDEPENDENT CLAIMS are included for: (1) a device for supplying the fluid on sample carrier; and (2) method for supplying the fluid on sample carrier. USE - Fluid reception device for supplying the fluid on sample carrier useful for the analysis of substance in biotechnology field. ADVANTAGE - The fluid reception device avoids cleaning and disinfection of sample container and ensures simple, safe and economical analysis of sample in accurate and time consuming manner by avoiding the danger of contamination of the sample.
