This bench-top dry-block heater features a single-knob temperature controller (ambient to 150 °C, ±2 °C accuracy) and a power-on indicator light. The removable top plate accepts up to 16 tubes via interchangeable foam-lined clips, so you can secure test tubes, vials or capillaries directly into the heated block—no water or oil bath required. Uniform conduction heating makes it ideal for enzymatic incubations, sample prep, melting-point screening and other multi-sample workflows in chemistry and biology labs. Listing includes the heater base, multi-position block plate and spring-clip mounting set.
