Intended use
JULABO recirculating coolers have been designed for temperature application to specific fluids. The
pump connections can be used for cooling applications in an external circuit at a constant temperature.
JULABO water baths are not suitable for direct temperature control of foods, semi-
luxury foods and tobacco, or pharmaceutical and medical products. Direct temperature
control means unprotected contact of the object with the bath medium (bath fluid).
