Laboratory Refrigerators

A domestic fridge cools unevenly and swings in temperature as it cycles, which risks temperature sensitive samples. A laboratory refrigerator holds a tight, even temperature with forced air distribution and monitoring. It also offers alarms and logging that a household unit lacks. For anything valuable or regulated, the controlled unit protects the material and the records.

Blood products, vaccines and medicines often must stay within a narrow validated range with documented monitoring, which specialised units provide. General reagents may only need a standard lab fridge. Match the grade to the requirement and any regulation you work under. Tell the seller what you store so they can confirm whether a specialised unit is needed.

Flammable samples need a spark safe refrigerator with the ignition sources removed from the interior. A standard fridge with internal electrical parts poses a risk with flammable vapours. Check that the unit is rated for flammable storage if that is your need. Ask the seller to confirm the interior is spark safe before you rely on it.

Check that the unit holds an even, stable temperature and inspect the door seals for wear. Confirm the monitoring and any alarms work and that the interior is clean and undamaged. For specialised units, verify the safety or logging features function. A fridge with a recent service and confirmed performance is a sound buy.

You contact the seller directly through the listing, with no middleman, and agree the sale and any inspection. Ask for photos of the interior and seals and a temperature reading if it helps. Sellers on the marketplace are verified, which supports the exchange. Agree the terms before you complete the purchase.
