So-Low | Laboratory Chest Style Multi-Purpose Freezers To -45°C | 3–25 Cu Ft Low Temperature Storage
At Alto Med Supply, we offer So-Low Multi-Purpose Chest Freezers to -45°C, designed to provide dependable laboratory-grade cold storage for research, medical, and industrial environments.
Available in capacities ranging from 3 to 25 cubic feet, these freezers maintain stable temperatures from 0°C to -45°C, making them suitable for storing biological samples, reagents, epoxies, and other temperature-sensitive materials.
Each unit features a heavy-duty cold-rolled steel exterior and a digital microprocessor controller that ensures precise temperature control with a dual display for easy monitoring of both the setpoint and internal temperature.
To help safeguard valuable samples, these freezers include a comprehensive alarm system with audible and visual alerts for temperature fluctuations or power interruptions, supported by an integrated battery backup.
Built for demanding laboratory and industrial applications, the freezers utilize a single-stage hermetic motor compressor and high-density CFC-free polyurethane foam insulation to support consistent temperature performance and efficient operation.
The manual defrost design helps prevent temperature spikes often associated with automatic defrost cycles, making these units well suited for storing heat-sensitive biological materials or industrial products.
Manufactured in the USA and operating on standard 115V power, these freezers feature a low-profile chest design with swivel casters for easy mobility and convenient placement in laboratory spaces.
Through Alto Med Supply’s online store, customers can access reliable So-Low laboratory chest freezers built for consistent low-temperature storage and long-term performance.

Outdoor Wheelchair for Recreation
I bought this wheelchair to be used outside to help me get to and from our pool and hot tub. It works great.

Great Service. Good Purchase.
I think that I received the Rollz Electric a day or two after ordering. Great service!
First outing was an overnight at Disneyland. As with all wheelchairs, this chair will take some getting used to. As my husband's caregiver, I use the electric drive-assist function as I push the chair. It definitely makes pushing easier. There is a learning curve. Whenever you take your hand off the chair handles for 5 seconds, you get an error message and have to reset to continue. This could be improved. The back wheels are (naturally) wider than the non-electric Rollz Motion chair, and that takes getting used to maneuvering through doorways and tight spaces. We are having a Surelift 88 installed in the back of our Prius because at around 60 lbs, the Rollz Electric is too heavy for me to lift. Overall, I'm happy with the purchase.

Outstanding product and service by office liaison Jean
The Nano lift arrived in excellent condition. We were impressed with the quality of engineering and manufacturing that went into this product ( I had a metal fabricating shop so I can appreciate quality and precision).My friends, an electrician and carpenter and I installed it in less than a day. I would like to point out that the installation instructions were poor and could use much improvement. We had to refer to the bar code for special videos on many items. Many of these referenced the Hercules lift and not the Nano. My thanks to your office liaison JEAN who did an outstanding job getting us thru the purchase and transport issues we had.THANK YOU JEAN. Yours truly Fred Roesslein
