Products A-Z II Ultra-low Temperature Freezer

Lexicon® II Ultra-low Temperature Freezer

Uncompromised Protection for Your Samples

Ultra-Low Temperature (ULT) Freezers are widely used in scientific research for long-term storage of samples. As ULT freezers are often operated at -80°C continuously for years, reliability is of paramount importance to the researchers.

Constructed from high-quality proven components with energy-efficient refrigeration design, Esco Lexicon® II ULT freezers provide top-notch protection that can withstand the test of time to guarantee the integrity of your samples. Superior performance, lower energy costs, better protection.

Gold Controller

  • Simple, intuitive operation
  • Large display of actual temperature with a simultaneous display of set temperature and ambient temperature
  • USB interface allows transfer of temperature data and the last 20 system events
  • Advanced input voltage Buck/Boost transformer protects critical freezer components
  • Additional sample protection

Fast Pull Down

  • Pull down time is the time required to bring down the temperature of the ULT freezer from ambient to the set temperature
  • Esco Lexicon® II has a short pull down time which signifies an efficient refrigeration system

Fast Temperature Recovery after door opening

  • Esco Lexicon® II recovers temperature in minutes following a 1-minute door opening
  • Fast recovery in temperature ensures the integrity of stored samples

Excellent Uniformity

  • Uniformity test measures the difference between the coldest spot and warmest spot in the freezer chamber when the freezer is operating at set temperature
  • Esco Lexicon® II has excellent uniformity under normal operating conditions
  • Guarantees that all samples are at the correct temperature

Extended warm-up Time during a power failure

  • Warm-up time measures the time taken for temperature to rise (from -80°C to -50°C) when the power is interrupted
  • With a robust insulation system in place, Esco Lexicon® II has the best warm-up time among the freezers compared on the right*. Slower warm-up during an extended power failure buys the user time for carrying out a back-up plan.
