DEVICE AND METHOD FOR VISUAL IDENTIFICATION OF SAMPLE POSITIONS IN PLATES WITH MULTIPLE WELLS, AND USE OF THE DEVICE

摘要

A pattern or screen (31) placed at a distance under a sample well in a multi-well plate is observed through the sample well and will on the addition of a sample change shape and size in such a manner that wells in which samples have been added can easily be distinguished from wells without sample solution. The refraction of the sample itself is utilized for indication in a method, a device and a utilization for distinguishing of sample wells in which sample solution is added. An embodiment of the device comprises a light source (40), a patterned surface (31), a holder means (11) for carrying a multi-well plate on a masking screen (20).
