The embodiments described herein relate to systems and methods for producing an evaporation barrier in a PCR vial. In some embodiments, beads with a particular distribution in diameters can be used to produce a barrier for reducing the evaporation of liquid PCR samples within the PCR vial. In some embodiments, the beads can be pre-filled in the PCR vial. In use, liquid samples and/or liquid reagents can be introduced in the PCR vial prefilled with the beads, such that the beads can be driven to the surface of the liquid PCR sample through the buoyancy of the beads. |
