HNZXIB86° (-136°F) Ultra Low-Temperature Freezer (20L), 110V Portable Lab Cryogenic Freezer, Ultra Cold Medical Countertop Refrigerator for Laboratory Sample Storage or Transfer Refrigerator

It was packed great. Somehow a piece of the plastic cover got cracked. Sent pictures. Got my new piece n a few days. They were awesome through every step of the process.

Unit worked flawlessly for 3 months - Then hurricane Helene took out the power for a week. When we restarted the unit, the temperature cycles between ambient and -80C. Access to parameters other than setpoint cannot be achieved as described in the operation manual. Need help to resolve this, but not sure who to ask.We have a second unit that was not impacted by the power loss. It continues to work flawlessly.

This thing is loud but seems to be working well.

Came as advertised. Temp holding at -70 but temp on box says -80. - more than adequate.

We use this to store our Covid vaccines. It has held up well and is as described. Great product for the price.

Maintain temp accurately. Sturdy construction. Was able to place 1100 doses of the Pfizer Covid-19 vaccine with plenty of room to spare.

We purchased this small one as we mainly use it to freeze our samples for freeze-drying. Due to its relatively small size and extremely low temperature, our samples are frozen quickly. We also use it to store some samples. The size is perfect for us and is fit under the bench. It meets all our requirements. Highly recommended.
