Quiet - Low Noise Operation

• According to OSHA 1910.95 Occupational Noise Exposure

Regulation, the sound level of the work place has to fall below

90 dBA for an employee who works 8 hours/day.

• Total noise in a lab is highly dependent upon the equipment

that emits the greatest amount of noise.

• Esco Lexicon

ultra-low freezer has a noise level of

approximately 56 dBA*. This ensures a quiet and pleasant

working environment for lab users.

* Units were factory tested under controlled environmental conditions per Esco method. Esco does not guarantee identical results in the ﬁeld under differing conditions.

Original report available upon request. UUS-668A-1 units were used for all the tests above.

** Average value of the Brand S to Brand F.

Large Reserve Capacity

• Reserve capacity test records the lowest temperature the

freezer is able to sustain when a heat source is placed in

the freezer. This resembles real life situations when hot

samples are placed in the freezer. The lower the temperature

the freezer can sustain, the higher chance the freezer can

maintain the set temperature when warm samples are placed

in the freezer.

• Esco reserve capacity surpasses that of all major brands

tested above.
