Block Heaters
Block heaters and coolers use interchangeable, modular blocks for housing tubes, vials, reaction vessels, and other laboratory containers. Both analogue and digital models offer repeatable results and temperature stability. An array of blocks can be purchased separately as well to meet specific needs. Shaking heaters and coolers completely mix samples at a designated temperature for homogenous blends. Sample concentrators feature quick sample evaporation when used with block heaters.
