Cryostatting

To provide such possibility for customers chromatograph “Crystallux-4000M” can be supplied by two kinds of cryostatting devices::

• Cryostating device with refrigerant – liquid nitrogen, herewith lower temperature limit of thermostat reaches 100 °C;
• Cryostating device without refrigerant on the basis of industrial air conditioner, at that lower temperature limit of thermostat reaches -5 °C (see. pic.).
