The powerful and robust CORIO™ laboratory circulators provide the exact temperature, absolute precision and a wide working temperature range. The CORIO™ C immersion circulator is the basic model, it is ideal for standard internal applications, the CD model is more advanced and can used for temperature control of external applications if required. The jet nozzle allows continuous adjustment of the pump stream in the bath. The stainless steel baths are durable and have an integrated drain tap (except B5). These open heating bath circulators are ideal for temperature control of samples, preparation of samples for serology and clinical chemistry, analysis, and material testing. The CD-B units are ideal for external temperature control applications in combination with measuring instruments, measuring cells, photometers, refractometers and polarimeters.

Their compact dimensions enable Ministats® to be placed in the smallest of spaces, for example in a laboratory fume cupboard or inside technical plant. Despite their minimal size the systems have a wide variety of features and offer performance levels suitable for temperature control of photometers, refractometers, viscometers, distillation apparatus, reaction vessels and mini-plants. They are mainly used for external applications, however the bath opening allows objects to be thermoregulated directly in a thermostat bath. A powerful pressure/suction pump with an infinitely controlled rotational speed ensures optimum circulation. The maximum pressure can also be regulated by an optional pressure sensor, meaning that sensitive glass reactors and apparatus can be protected from breakage. Ministats® have the 'professional' level Pilot ONE® controller as standard with a colour TFT display and convenient operator guidance. Analogue NAMUR connections are available via the optional Com.G@te module allowing Ministats® to be integrated into plant and process control systems. The Pilot ONE® multi-touch controller features a brilliant 14,5 cm touchscreen with graphic functions and easy navigation menu in 11 languages. All important operating parameters and temperature values are clearly displayed on the touchscreen. The favourites menu, one-click operation and the integral technical glossary mean operation is simple. Integrated USB and Ethernet ports allows connection to a PC or network, e.g. for remote control or data transmission.
