System for thermocycling of fluids in cartridges
First Claim
1. A system for thermocycling of fluids in cartridges comprisinga) a cartridge with at least one heat conducting wall and at least one light transparent wall, the cartridge having a fluid inlet and a fluid outlet which are connected by a channel, said cartridge having a protrusion into the channel, such that the channel is longer than the shortest distance between the fluid inlet and the fluid outlet to allow bubble-free flow-through filling of the cartridge, wherein the fluid inlet is directly connected to a top wall, a bottom wall, and a pair of sidewalls, wherein the side walls form an angle of 100°
- -150°
with the walls of the fluid inlet, and wherein the fluid outlet is directly connected to the top wall, the bottom wall, and a pair of side walls, wherein the side walls form an angle of 100°
-150°
with the walls of the fluid outlet,b) a thermocycling unit in thermal contact with said heat conducting wall of said cartridge,c) a light source for transmitting light into the interior of said cartridge through said light transparent wall of said cartridge which is arranged substantially perpendicular to said heat conducting wall,d) a light detector for detecting light emerging from the interior of the cartridge through said light transparent wall,e) a fluid providing unit coupled to an inlet of the cartridge for providing the cartridge with fluid by flow-through-filling.

Abstract
System for thermocycling of fluids in cartridges comprising a thermocycling unit in thermal contact with a first substantially planar and heat conducting wall of a cartridge, a light source for transmitting light into the interior of said cartridge through a second light transparent wall of said cartridge which is arranged substantially perpendicular to said first wall, a light detector for detecting light emerging from the interior of the cartridge through said second wall and a fluid providing unit coupled to an inlet of the cartridge for providing the cartridge with fluid and an outlet of the cartridge to drain gas when the cartridge is filled with fluid. The invention further concerns a cartridge for conducting the thermal cycling of fluids.

15. A cartridge for conducting thermal cycling of fluids, comprising
a) a substantially planar and heat conducting wall, b) a light transparent wall which is disposed substantially vertical to said heat conducting wall, c) a fluid inlet for providing the cartridge with fluid, d) a fluid outlet for draining fluid or gas from the cartridge, e) a channel connecting the fluid inlet and the fluid outlet, wherein said cartridge has a protrusion, into the channel, such that the channel between the fluid inlet and the fluid outlet is longer than the shortest distance between the fluid inlet and the fluid outlet to allow flow-through-filling of the cartridge to avoid bubbles in a measuring section of the cartridge, wherein the fluid inlet is directly connected to a top wall, a bottom wall, and a pair of side walls, wherein the side walls form an angle of 100° - -150°
with the walls of the fluid inlet, and wherein the fluid outlet is directly connected to the top wall, the bottom wall, and a pair of side walls, wherein the side walls form an angle of 100°
