Cold Storage UK — Temperature Control for Research Equipment and Material

Most temperature-sensitive research material is stored at 2–8°C — standard fridge temperature — with some items kept frozen for the long term. Getting storage right is mostly about location, protection from light and knocks, and knowing what to do when the temperature drifts.

Fridge Storage Done Properly

• Middle shelf, not the door. Door shelves swing through warm air every time the fridge opens; the back of a middle shelf is the most stable zone.
• Not touching the back wall — contact with the cooling plate can freeze contents, and freezing is usually more damaging than mild warming.
• In a case, not loose. Glass cartridges and vials chip easily. A rigid storage case keeps them upright, dark and separated.

Light, Vibration and Labelling

Light degrades many stored materials — a closed case or the original carton deals with this. Keep storage away from compressor vibration where possible, and label everything with the date prepared so nothing outlives the period given in your supplier’s documentation.

Filled Cartridges and Pens

A filled 3ml cartridge goes back in the fridge between uses, ideally in its case with the pen stored separately at room temperature if you prefer — the pen mechanism itself does not need refrigeration. See filling and using a cartridge for handling technique.

Away From Home

For anything beyond a short trip, treat transport as its own problem — insulated carrier, conditioned packs and a plan for fridge access. Our travel guide covers coolers, flying and temperature excursions in detail, and the insulated cooler bag is built for exactly this.
