High end HPLC Column Ovens are available which utilize the proprietary radiation technology to achieve temperature accuracy of +/- 0.1°C with maximum temperature attainable up to 140 °C. The HPLC Column Oven is capable to handle up to 4 columns at a time. These HPLC colum ovens can be contorlled through RS 232C loop or through RS 485 loop over distances of upto 900 meters. These systems are equipped with a powerful blower which helps maintain a unform temperature profile in the oven and minimizes gradient..
