A waterless alternative to contamination-prone traditional laboratory water baths was designed to deliver extremely good temperature uniformity while eliminating a major source of contamination in laboratories: water. The unit is always on, ready for the next experiment, so scientists don’t have to plan around warm-up times. There is also no burn-out risk because there is no water to evaporate. The bath keeps samples organized, naturally holding vessels in place without the need for racks, floats and bottleneck weights. Vessels that can be used with the bath are not limited to watertight containers, so scientists can safely incubate multi-well plates, petri dishes, and open-top samples at any angle.
