-30°C Plasma Freezers From Undercounter to Full Size, Plus a -40°C Chiller
This collection carries 10 plasma freezers from Follett, Thermo Scientific, Migali Scientific and Corepoint Scientific: -30°C units from a 4.5 cu ft undercounter to 29.5 cu ft uprights, NSF/ANSI 456 certified Infinity series models, and a -40°C to -30°C plasma chiller for faster freezing and a lower holding point.
Plasma storage temperature and monitoring requirements are set by the facility's accrediting body. This page covers which unit fits which capacity, footprint and temperature specification.

Compare Plasma Freezers
| Model | Type | Capacity / temp | Best for |
|---|---|---|---|
| Follett FZR5PLP undercounter | Undercounter, -30°C | 4.5 cu ft | Satellite plasma stock under a bench |
| Follett FZR8 plasma chiller | Plasma chiller, -40 to -30°C | 7.5 cu ft | Faster freezing, lower holding point |

Which Temperature Specification?
Most units here hold -30°C, which is the common plasma storage specification. The Corepoint NSBF231 runs -25 to -15°C, for facilities whose protocol specifies that range. The Follett FZR8 plasma chiller reaches -40°C, which freezes product faster and holds a lower point; whether that is required depends on the products stored and the accrediting body's standard. Match the unit's range to the written protocol rather than choosing the coldest available.
Which Capacity and Footprint?
Undercounter for satellite stock: the Follett FZR5PLP at 4.5 cu ft. Mid-size uprights for a transfusion service: the Thermo TSX1230LA at 11.5 cu ft, the Migali EVOx 1F-BB and the Thermo XBF40D-MD. Large single door: the Follett FZR20i at 19.7 cu ft, the Corepoint NSBF231 at 23 cu ft and the Follett FZR25i at 24.6 cu ft. Largest: the Migali EVOx 2F-BB double door and the Thermo TSX3030LD at 29.5 cu ft. A freezer loaded beyond capacity recovers slowly after each door opening, so size with headroom.
Is NSF/ANSI 456 Required?
NSF/ANSI 456 is a performance certification covering temperature uniformity and recovery after door opening. It was written for vaccine storage and some facilities now specify it for plasma freezers as well. Follett's Infinity series carries it: the FZR20i and FZR25i. Whether it is required is a question for the facility's accrediting body. All units should be paired with continuous monitoring from Temperature Data Loggers and alarms from Refrigerator Alarms.
Frequently Asked Questions
Plasma freezer or plasma chiller?
A plasma freezer holds -30°C for storage. A chiller such as the Follett FZR8 reaches -40°C, freezing product faster and holding a lower point. Which is needed depends on the products stored and the written protocol.
Which plasma freezer for a satellite location?
The Follett FZR5PLP undercounter at 4.5 cu ft. It fits under a bench and holds a working stock near the point of use.
Which unit if my protocol specifies -25 to -15°C?
The Corepoint NSBF231 at 23 cu ft runs that range. The other units here hold -30°C or colder.
Do I need NSF/ANSI 456 on a plasma freezer?
Check with your accrediting body. Where it is specified, the Follett FZR20i and FZR25i Infinity series carry the certification.
What capacity for a hospital blood bank?
The Thermo TSX3030LD at 29.5 cu ft or the Migali EVOx 2F-BB double door are the largest here. Size to peak inventory with headroom, since a full freezer recovers slowly after each door opening.
