Clinics storing vials and other temperature-sensitive products need storage that holds a stable temperature and records it. Household refrigerators cycle widely and often have freezer compartments that can freeze stock, which is why CDC storage guidance recommends purpose-built units.
Here's what to look for.
Why purpose-built units
Medical and pharmacy refrigerators circulate air with fans, recover quickly after the door opens and keep a tighter temperature range than household units. CDC storage guidance for vaccines (a useful benchmark for other refrigerated products) recommends purpose-built or pharmaceutical-grade units and continuous temperature monitoring.
Features to compare
- Temperature range: refrigerated storage is commonly 2–8 °C (36–46 °F). Check how tightly the unit holds it.
- Digital data logger with a buffered probe, a display outside the unit and downloadable records.
- Alarms for temperature excursions and door-ajar, ideally with remote notifications.
- Capacity and shelving: adjustable wire shelves or drawers to keep air moving.
- Locks to control access.
- Undercounter vs upright to fit your space.
Placement and daily practice
Place units away from exterior walls, vents and direct sun, with clearance for airflow, and plug them into an outlet that can't be switched off by accident. Don't store food or drinks in medication units. Record minimum and maximum temperatures daily and keep the logs.
Sizing a unit
Size the unit for your peak inventory plus room for air to circulate; overpacked refrigerators hold temperature poorly. Leave space between products and the walls, and avoid storing anything in the door.
Questions to ask your supplier
- How tightly does the unit hold its setpoint, and how quickly does it recover after the door opens?
- Is a data logger with a buffered probe included?
- Can alarms notify staff remotely?
- Is there a lock?
- What are the warranty and service options?
Plan for outages
Know what you'll do in a power outage: where stock goes, how you monitor temperature, and who gets the alarm notification after hours.
Frequently asked questions
Can I use a regular refrigerator for vials?
Purpose-built units are recommended because they hold temperature more consistently and recover faster after the door opens. Household dorm-style units with freezer compartments are especially risky.
What temperature should a medical refrigerator hold?
Refrigerated products are commonly stored at 2–8 °C (36–46 °F). Always follow the product's own storage instructions.
Do you supply data loggers?
Yes. Many units include them, and we can add a standalone logger with a buffered probe and alarms.
Should we keep temperature logs?
Yes. Record minimum and maximum temperatures daily, and keep the logs as your protocols require.
