Product Description:

The CO50 Chilling/Heating HPLC Column Oven offers the reliability of a completely solid-state system. The only moving parts in the unit are the cooling fans, while its Peltier-based design removes the need for compressors or CFCs. The energy efficient CO50 uses a maximum of 120 watts of power—less than many light bulbs.

The CO50 chamber is insulated with chemically resistant silicon rubber. The case construction is ABS plastic and sheet steel painted with chemically resistant epoxy paint. The cover is machined from block polycarbonate to resist heat and chemicals.
