A biological analysis system can include an excitation module and an emission module. The excitation module can include a collimator element for receiving excitation light from the excitation light source and transmitting collimated excitation light in a first direction, and a plurality of excitation mirrors arrayed along the excitation light path, each excitation mirror disposed at an acute angle relative to the first direction and configured to reflect collimated excitation light along a second direction. The emission module can be positioned to receive excitation light transmitted along the second direction and can include a sample block comprising a plurality of sample receptacles positioned to receive a beam of collimated excitation light, and a plurality of photodetectors configured to receive emission light transmitted from a respective sample receptacle in a direction transverse to the second direction of the excitation light path.

Biological analysis devices and systems

The invention relates to a method for producing a friction-welded connection between a plurality of superimposed flat components held together by a connecting member, wherein a collar of said connecting member rests on an upper component and the front end of said connecting member forms a friction-welding zone with a lower component, said friction-welding zone being produced by rotation and pressure of the connecting member. After formation of the friction-welding zone, the rotation of the connecting member ceases at the end of a first step and, in a second step, upon cessation of the rotation of the connecting member prior to contact of the collar with the upper component, a pressure is exerted on the connecting member by a pressure-applying tool, said pressure pressing the collar against the upper component because of a deformation.

Method for producing a friction-welded connection and design of the friction-welded connection

The invention relates to a friction welding joint of a plurality of two-dimensional components positioned on top of each other, which are held together by means of a connecting body, which rests on an upper component by means of a collar. The connecting body is configured as a pipe piece, and the upper component is penetrated by the connecting body having a front annular cutting edge by means of rotation and pressure, wherein the connecting body, after cutting through the upper component with the front thereof and receiving the cut-out material of the upper component in the hollow space thereof, together with the lower component forms a friction welding zone created by means of rotation and pressure of the connecting body.
