Lexicon® II Ultra-low Temperature Freezer

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.
