Physical properties

Please note the safety and hazard warnings before use. You can download the corresponding safety data sheet in the download center or simply request it from us.

Please consider the volume of the external circuit as well as the bath volume when ordering the quantity.

Open systems are atmospherically open, half-open systems are open baths with lids (e.g. water baths, cooling thermostats). The thermally active heat transfer medium in closed cold oil superimposed circuits has no direct contact with the ambient air (e.g. LAUDA Integral XT).
