Overview

Chest style Ultra-Low Temperature Freezers are designed for a variety of uses including shrink fitting, and ultra cold storage of product down to -85°C. The chest freezer style allows for efficient storage. Freezer Sizes range from 2 to 27 cubic feet capacities.

Manufactured in Cincinnati Ohio, So-Low Ultra-Low -85°C freezers are produced with high quality craftsmanship, heavy-duty materials, and over 50 years of experience. These freezers use a cascade refrigeration system, providing reliable and durable environmental conditions for your product’s vital temperature requirements. Available in wide variety of sizes and styles.

Superior Construction

Ultra low freezers have a 16-ga. exterior (cold rolled steel). Interiors are 14 gauge vs. competitions 16 gauge.Ultra low 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.

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.

Dependability

Laboratory professionals all over the world have recognized the dependability and efficiency of So-Low Ultra Low 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: 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 Ultra Low Freezers are manufactured at the time the order is placed and go through extensive testing before they are released. A 4-6 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 of the C85 Series Chest Freezers?

The temperature stability is +/- 3°C. For example, if you set the temperature to -80°C the compressor will engage at -77°C then turn off again at -83°C. This is done such that the compressor has some "off" time between cycles and reduces wear on the compressor, thereby extending the life of the freezer.

 

Can the chest freezers be placed on casters? Are the casters included and pre-installed?

Yes, all of the So-Low ULT chest freezers come with casters pre-installed.

 

What does the warranty cover? Is there a longer warranty on the compressor? there an extended warranty available?

The warranty is a 1-year parts & labor warranty, which includes the compressor. Extended compressor warranties are available for purchase which extend the compressor warranty for 4 years (5 years total from date of purchase) but the extended warranty covers parts only, not labor. Extended warranties must be purchased at the same time as the freezer. Please contact us for pricing information.

 

Are the So-Low Ultra-low Chest Freezers UL listed?

No, but they are ETL listed, which is a similar marking from a different organization. Just like UL listing, ETL listing serves as proof of product compliance to North American safety standards in both the US and Canada.

 

Do the So-Low ULT Chest Freezers Come with a locking mechanism?

The latch to close the door has a space for a padlock or combination lock to be inserted. There is not a keyed lock built into the freezer.

 

If the gaskets need to be replaced, can we order replacement gaskets? Is installation of new gaskets a complicated procedure?

Yes, replacement gaskets are available. There are two gaskets - one in the lid and one around the body where the lid makes contact with it. Installing them requires use of a staple gun and adhesives. If you're handy, or you have facilities staff at your institution, you can likely install the replacements yourself.

Average quality lightweight throw, not sold on the color
Color: Southern Blues, Size: Throw (50 in x 60 in), Color: Southern Blues, Size: Throw (50 in x 60 in)
This blanket is fairly soft and lightweight, and better suited for the summer months. I don't think the texture and "Southern Blues" color looks as nice in person as in the photos; less cozy and more like a spare blanket you might find in a hotel closet. Interestingly the care tag says that the outer faces are cotton, but the blanket feels polyester and the content tag indicates the same. The stitching and durability feel ok, and it will probably hold up for the occasional machine washing and low heat drying. Overall it's a fine warm season throw but not particularly notable. I would probably recommend one of the darker colors.

So easy to wash!
Color: Southern Blues, Size: Full/Queen (90 in x 90 in), Color: Southern Blues, Size: Full/Queen (90 in x 90 in)
Two things I love about this coverlet: 1. It's so much easier to wash than a duvet! Or even a duvet cover or a regular blanket, for that matter. The queen-size coverlet fit easily in my washer, and I could have put in another if I had had one. It stayed loose and balanced in the machine - the washer didn't have to readjust its balance during the spin cycles. In the dryer, it didn't wad up into a ball that had to be shaken out every few minutes. It came out feeling softer and looking good, with no wrinkles. 2. It's thinner than a duvet and suitable for warm weather, yet those three stitched layers give it substance and weight that I find more comfortable than sleeping under a pile of fluff or a bed sheet. The soft pastel green color with cream lining (not really reversible due to the hem) is fresh and reminiscent of the 1950s coverlets that my grandmother made. Crocheting was one of her passions, and she'd create huge lacy doilies that lay across the foot of the coverlet. Very pretty look.

Great summer blanket.
Color: Black, Size: Full/Queen (90 in x 90 in)
I purchased this Berkshire 3-layer fleece blanket, and it has quickly become my go-to for my queen size bed. It fits perfectly with plenty of overhang, making it look great as a top layer or a middle layer.What I love most is the breathability. While the material is technically fleece, the 3-layer design provides a nice "cotton-like" feel that doesn't feel heavy or stifling. I tend to sleep hot, and this blanket does a fantastic job of keeping me cool and comfortable through the night while still providing just enough cozy warmth.At this price point, the value is good. It feels much higher quality than other thermal blankets I’ve tried, and it holds up well in the wash without pilling or losing its softness. If you're looking for a versatile, lightweight blanket that works year-round, this is a solid choice. Highly recommended!

Soft, Warm, lightweight, Cozy
Color: Cream, Size: Full/Queen
When I first received this blanket I washed it by itself in cold water with detergent. I did not use a fabric softener or a fabric sheet. I air dried it completely and then put it in my dryer on air fluff for 10 minutes. No shedding and it came out just like I received it. I was concerned about shedding with some of the reviews but I had no issues with that whatsoever. It's warm yet lightweight. I didn't want anything that would make me overly hot because I'm always hot anyway. It takes that cool edge off when you still want your overhead fan on. My daughter said she likes it better than the one she has. I can't remember the brand. I feel it has a good quality. Just make note to wash it as instructed and it'll hold up well and look just as nice as the way you bought it. I'm not sure how the other reviewers that didn't leave 5 stars washed there's, but it couldn't have been the correct way.

Soft, warm, sometimes shed
Color: Shadow Grey, Size: Full/Queen
LOVE these blankets! The only downside is some of them shed. They will keep you so warm and they are very soft.
