The AT-330 External Column Oven is a precision temperature control device designed to stabilize and regulate the column temperature in high-performance liquid chromatography (HPLC) systems. By maintaining consistent thermal conditions, it improves chromatographic reproducibility, resolution, and peak shape, especially for temperature-sensitive compounds and gradient elution methods. Engineered for external integration, the AT-330 is compatible with a wide range of column sizes and HPLC systems, making it a vital accessory in pharmaceutical, environmental, chemical, and research laboratories.
