Combined with our nation-wide service network, our Low Temperature Freezers have various options for additional temperature recording devices, providing the highest level of quality temperature management and transcription.

So-Low's Superior Construction

Laboratory freezers have a 16-ga. exterior (cold rolled steel). Interiors are 14 gauge vs. competitions 16 gauge. Uprights have adjustable shelves. Laboratory freezer interiors are galvanized, non-corrosive steel. Galvanized steel conducts temperature more efficiently than stainless steel. This creates less stress on compressors making them run cooler and longer.

So-Low's Digital Control

So-Low is the only Ultra-Low temperature manufacturer to utilize a dual display digital temperature control. A red LED display indicates the actual interior chamber temperature while a green LED display located directly below the red display shows the actual setpoint temperature. This will give assurance that the freezer is operating at the correct temperature range whereas other manufacturer's temperature controls show only the actual temperature and not both the setpoint and actual temperature.

So-Low's Dependability

Laboratory professionals all over the world have recognized the dependability and efficiency of So-Low Laboratory Freezers, the first to combine all of these performance features and deliver a level of quality construction, reliability and value unequaled anywhere in the world.

Performance testing is your assurance of So-Low Laboratory freezers' dependability. Every freezer is fully tested under the most demanding conditions for seven days. The constant ultra-low setpoint operating temperature is assured in warm temperature environments. Dependability is backed up by a 12 month warranty. Technical assistance is provided by a Nation-Wide-Network of service companies.

Please note: So-Low refrigerators and freezers are manufactured at the time the order is placed and go through extensive testing before they are released. A 2-3 week lead time should be expected.
