Abstract: The present invention pertains to a method suitable for analyzing the temperature control of a device which is supposed to establish a defined temperature in a micro-environment, said method comprising a first Optical Temperature Verification step which comprises a) providing one or more thermochromatic liquid crystals in a micro-environment, wherein each thermochromatic liquid crystal has a specific event temperature, b) providing one or more temperature dependent luminophores in a micro-environment, c) varying the temperature in the micro-environments and irradiating the micro-environments with light, d) recording the luminescence of the one or more temperature dependent luminophores when the event temperature of the one or more thermochromatic liquid crystals is reached in the micro-environment and wherein said method preferably comprises a second Optical Temperature Verification step, which comprises the following a) providing one or more temperature dependent luminophores that were used in the First

Abstract: The invention relates to a sample container, comprising a housing which forms a sample space for receiving a sample and has at least one circular opening which extends in a channel-shaped manner into the sample space, and further comprising a spherical closing element, wherein the diameter of the closing element only exceeds the diameter of the opening channel in at least one (closing) portion to such an extent that the closing element can be fixed in a force-locked manner by its largest circumference in the closing portion, wherein the spherical closing element is in contact with the housing, and the opening channel between the closing portion and the inner opening forms a protrusion which reduces the opening cross section of the opening channel with respect to the opening cross section in the closing portion.
