Lab Armor Beads are a revolutionary modern day concept for replacing water in baths, ice in ice buckets and aluminum blocks in dry block incubators. These unique thermal technology beads have a broad temperature range of -80°C to 180°C. Lab Armor Beads can also be used to replace aluminum blocks in dry block heaters. Help to maintain a clean and green environment in the laboratory. Improves energy efficiency of standard water baths by over 50%.
