Fastrecovery in temperature ensures integrity ofstored samples.EXCELLENT UNIFORMITY• Uniformity test measures the differencebetween the coldest spot and warmest spotin the freezer chamber when the freezer isoperating at set temperature.• Esco Lexicon® has excellent uniformity undernormal operating conditions*. This guaranteesthat all samples are at the correct temperature.Time (min)120 110Warm-up time from -80°C to -50°C**304EXTENDED WARM-UP TIME DURINGA POWER FAILURE• Warm-up time measures the time taken for temperature to rise up(from -80°C to -50°C) when the power is interrupted.• With a robust insulation system in place, Esco Lexicon® has the bestwarm-up time among the freezers compared on the right*. Slowerwarm-up during an extended power failure buys the user time forcarrying out a back-up plan.120130110190210Warm-up time (min)Sanyo MDF-U73V (V.I.P)So-LowU85-25HaierDW-86L626ThermoScientificRevcoULT2586-10-DThermoScientificForma 906UUS-668A-1
