| abstract |
The invention relates to a sample holder device (100, 101) which is designed to hold biological samples (1), said device comprising a base body (10) having at least one wall (11) which is arranged to delimit a sample holder (12), wherein the at least one wall (11) comprises, at least on a surface facing the sample holder (12), a planar, carbon-based material which is impermeable to a liquid in the sample holder (12), wherein the carbon-based material has such a high carbon content that the carbon-based material is opaque and electrically conductive. The sample holder device comprises e.g. a dish, in particular a petri dish (101), a planar substrate, a multiwell plate, a sample beaker, in particular in the form of a beaker glass, a sample tube, in particular in the form of a test tube or a tube for cryopreservation (cryovial), and/or a hollow fibre. The invention also relates to methods for using the sample holder. |
