Cooling circulators are versatile for external temperature applications, featuring stainless steel internal baths. Available in various performance classes and temperature ranges, they offer efficient cooling for quick cool-down times. All models have a drain port for easy bath cleaning. Ideal for closed systems like refractometers, photometers, rotary-evaporators, distillation units, water baths, viscosity baths, flash point testers, foaming testers, and ductility tests. Objects can be placed inside the bath for these applications.
