Cole-Parmer Aluminum Block Heater Insert - Single Wide, 28mm Diameter Holes for Lab Equipment & Scientific Applications - Perfect for PCR Tubes, Microcentrifuge Tubes & Sample Vials

Interchangeable aluminum heating blocks provide excellent thermal conductivity and accommodate various test tubes, cups, and plates. Depending on the combination of blocks selected, plastic spacers (36620-67) can be used to fill a half-width recess, ensuring optimal thermal performance. Most blocks come with a separate hole to accept a thermometer. Order a flexi-block to accommodate multiple size tubes, vials, or cuvettes at once. Unskirted PCR plates can be heated in either size flexi-block. Skirted microtiter plates, deep-well plates, and PCR plates can only be incubated in the triple-width version.
