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.

Best slippers, beware Sizes may be off.
Size: Medium, Color: Charcoal Ragg Wool
I LOVE these sock moccasins shoes or whatever they are. I purchased 2 pair in different colors and the upper sock material was a significantly different material in its weave density and stretchyness. (blue more thin and stretchy than grey). I wear blue ones indoors, and the grey ones stay in the car for long car trips. Sizing: both pair I bought say 7-9mens 9-10women -- In how they actually fit they are 9-10 mens. The soles are leather with a thin bit of soft foam, in winter I can walk around in snow in them and the cold doesnt get through. Not that you should walk in snow with them since the leather is like a suede so it gets gross. You can put them through the washing machine and it makes them look good as new.

Is this a joke slipper?
Size: Large, Color: Charcoal Ragg Wool
Bought size large (men’s 9-10) this past year for my husband for Christmas. These are not made to fit a human being unless it is a severely skinny person with very very long feet. The feet are too big for him but the ankles are so narrow he can’t put them on, and my husband is actually very lean, he teaches martial arts for a living 6 days a week. I don’t believe I’ve ever seen a person in my entire life who simultaneously has long enough feet combined with skinny enough legs to fit these slippers. For a laugh we got our skinniest female friend to try them on and she could just barely squeeze her legs into them. I think she described it as “squeezing her skin off of her legs” or something like that, and then of course the feet were comically huge for her because she is so petite. We never got around to returning them and I just found them last night and remembered the whole incident. I tried to fit my forearm inside them but could not fit much past the wrist because they were too tight and I had a good laugh. I think I might cut them up and use the pieces to patch his old slippers that actually fit. To be fair we actually got a lot of laughs out of the product so it wasn’t a total waste. Buy them as a joke or save your money.

Great slippers.
Size: 14-15 Women/12-13 Men, Color: Light Grey Ragg Wool
They're great slippers. Literally my whole family, nuclear and extended, wears them. This is the 3rd pair I've bought. I usually wear a size 12, but these are a little big. Ill be washing them in hot water and drying them in...well...the dryer to see if they shrink. I can't recommend these slippers enough.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.
