Page 5: Operating Manual
Operating manual Intended use JULABO circulators have been designed to control the temperature of specific fluids in a bath tank. The units feature pump connections for temperature control of external systems (loop circuit). JULABO circulators are not suitable for direct temperature control of foods, semi- luxury foods and tobacco, or pharmaceutical and medical products. -
