Lab Armor® Beads are small, dry, metallic thermal beads designed to replace water in laboratory water baths and ice in ice buckets. Shields lab personnel from microbes and invadingorganisms with a concurrent thermal antimicrobial design. Beads and Bead Baths heat and cool more efficiently than typical water baths, heat blocks, and chill buckets. Lab Armor Beads will help you save time and money. No more hassling with emptying, cleaning, and refilling water baths. The bath stays on so there is no need to plan around warm-up times. Lab Armor Beads eliminate the worry about burnout because there is no water to evaporate. Data shows that most baths are compatible, no matter their age. An exposed or recessed thermocouple does not seem to affect the performance of the Beads. However, the location and configuration of the heating element can make a difference in heating uniformity. Most of the water bath design problems affecting performance of Beads, also affect the thermal performance of water. Circulating water baths are generally incompatible with Lab Armor beads. Available in 0.75, 2, 4 and 8 Liter volumes.
