LOIP FT-311-80 is a powerful instrument for precise temperature control in internal baths and external systems within the range -80…+100°С.
The cryostat is equipped with two-stage compressor refrigerator and intended, first of all, for applications at low and ultra-law temperatures. This high capacity cooling system provides very fast temperature decreasing - cooling down from +20 to -80°C takes only 90 minutes.
The model LOIP FT-311-80 controlled by the immersion circulator LOIP LT-300.


Beside general applications for cryostats, refrigerated circulator LOIP FT-311-80 also suits for
  • Freezing point determination
  • Chemical and biological investigations at low and ultra-law temperatures
  • Petroleum products cold behavior assays
  1. Pour point according to ASTM D97, ISO 3016
  2. Cloud point according to ASTM D2500, ISO 3015
  3. Cold filter plugging point according to ASTM D6371

Features and benefits:

  • Microprocessor PID thermo-regulator .
  • Intelligent automatic control system
  • Cascade refrigerating modules to provide high cooling capacities
