Bead Baths control the temperature of samples in metal beads instead of water or other liquid. This avoids possible contamination from water or other liquid warming mediums while allowing for easier sample organization without the need for racks or clamps. Bead baths are also easier to maintain as they do not need to be cleaned.
While bath beads can be used in most stationary water baths, these baths are specifically designed for use with beads and provide improved temperature uniformity. They are indispensable in applications where contamination or sterility is a concern.
