Portable cold, done properly.Zero compromises.
PeptidesFridge is a UK-based brand building portable 2–8°C coolers for vials and injection pens. Silent semiconductor cooling, a live temperature read-out and up to 30 hours of battery — so the cold chain follows you instead of ending at the kitchen fridge.
Cold that travels with you.
PeptidesFridge started with a simple annoyance: a domestic fridge swings between 1°C and 12°C every time the door opens, and nothing on the shelf tells you it happened.
So we built the opposite: a compact unit that holds a stable 2–8°C, shows the real temperature on the lid, runs silently without a compressor, and keeps going on USB-C, mains or a 12V car socket.
Every unit is temperature and battery tested before dispatch and backed by a two-year replacement warranty. We sell hardware, and we stand behind the hardware.
Four things every unit has to earn.
Temperature tested
Every unit runs a full cooling cycle against a calibrated probe before it is packed.
2-year warranty
Cooling module, battery and display covered. A failure inside two years means a replacement unit.
