Claim:
1. An arrangement for drying of a biological sample applied on a sample storage substrate, comprising: at least one sample storage substrate comprising a front side for receiving the biological sample and a back side, the sample storage substrate being formed of a paper material; at least one sample storage substrate holder; at least one chemical heat pad positioned below the back side of the sample storage substrate; a chemical heat pad holder that is hinged and moveable towards the sample storage substrate so as to position the chemical heat pad in proximity of the sample storage substrate; and a protrusion, wherein said protrusion is configured to activate said chemical heat pad to accelerate the drying of the biological sample on the sample storage substrate, wherein a ceiling surface temperature of said chemical heat pad is between 35 and 58° C., and wherein the sample storage substrate holder comprises one or more air passageways, the one or more air passageways being arranged to expose the sample storage substrate to air outside the sample storage substrate holder when the sample storage substrate holder is in a closed configuration.
