Overview

Chest style Low Temperature Freezers are designed for storing product down to -40°C. The chest style unit allows for efficient storage capabilities. Freezer Sizes range from 3 to 22 cubic feet capacities.

Manufactured in Cincinnati Ohio, So-Low's Low Temperature Freezers to -40°C are produced with high quality craftsmanship, heavy-duty materials, and over 50 years of experience. These freezers use a hermetic motor compressor refrigeration system, providing durable and reliable environmental conditions for your product’s vital temperature requirements. So-Low Low Temperature Freezers are available in wide variety of sizes and styles, to accommodate for each customer required conditions. 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.

Some of the accessories/options available for this product are factory installed and must be purchased at the same time your So-Low freezer / refrigerator is ordered. Please add them to your cart with your freezer / refrigerator before checkout so that they may be included with the submission of your order to the manufacturer for installation during production.

FAQ

What is the temperature stability / differential of the So-Low Low Temperature Chest Freezers?

While there is no specified temperature differential, based on the data which So-Low collects in testing every freezer prior to shipment, when the temperature setpoint is -40°C a temperature stability of +/- 5°C can be expected. (Higher temperature setpoints result in larger cycle temperature swings.)

This cycle temperature variance cannot be user-defined nor factory altered.

Quirky, small, and not for everybody
Color: Black/White/Black, Color: Black/White/Black
This is an attractive little watch, similar to the older Timex Expedition, but changes have been made. Like its earlier version, this is a small, light timepiece. The band is something different, with the case being held in place by an elastic insert sewn in. Pro - This watch stays put on the wrist, making it a good work watch. Con - pins will have to come out to remove band or change the battery. Another unique feature is the use of triangle slot retention screws on the back of the case, no doubt requiring a special screwdriver most folks probably don't have on hand. The band Velcro's into place, appears best for small or medium wrists, and stays where one puts it. In sum, this is a handy and attractive watch that is quite informal in appearance and will require some patience to perform battery changes.

Simple, easy to read, dependable, and affordable: all the important stuff!
Color: Black/White/Black
Its just a fine time piece for daily wear. Its light, its super easy to read both day and night. Its comfortable and it looks good on your arm. What more can you ask of a watch? If you want "fancy" go buy some high dollar metal case thing and pay three or four (or more) times what this watch cost. If you want to know what time it is and not spend a bunch of money, this is your baby. You can find cheaper watches, but you will not find a better watch at this price. I know, I have been wearing out watches for decades! My work is hard on watches. Things like using power tools, impact tools, hammers, welders, etc. These watches have never failed me and have lasted longer than watches costing far more. I got my first Timex watch nearly sixty years ago. I am still buying them as I have found nothing else that is more accurate or holds up under harsh conditions any better. You get what you pay for except with Timex. They give you MORE than you paid for.

I like the nylon strap.
Color: Black/White/Black
Watch itself is fine - doesn't stand out as something spectacular but is great for what it is. Definitely waterproof to about 30 feet deep - I've tested it snorkeling. The best thing is the strap - this nylon strap is much more comfortable than usual watch straps. There are a lot of nylon straps out there -- I think I prefer this one more than most of the others. the Velcro allows infinite adjustment, unlike straps with holes like a belt. And the way they did the looping of the band around itself seems to work really well. Better than another velcro strap I had many years ago ("the band") which was similar but didn't loop around itself the same way. This one is better - quicker and easier to put on and more easily adjustable.
