A PeptidesFridge cooler under temperature testing

Temperature hold

Each unit is held at its 2–8°C set point and logged before it is packed.

Certificates of Analysis

Battery cycled and runtime verified so the stated hours are the real hours.

Controlled synthesis

Lid seal, hinge and housing checked, then packed in protective foam.

Insulated shipping

Temperature-stable packaging with tracked UK & EU delivery and shipment protection.

PeptidesFridge cooler packed with its accessories

Our workflow

Documented from vial to bench.

Batch sampling
A representative sample from each production lot is pulled for QC before release.
±0.5°C accuracy
Set point verified against a calibrated probe across a full cooling cycle.
Mass spectrometry
MS confirms molecular weight and peptide identity match the reference sequence.
Protective packing
Foam-cradled with cable, adapters and insert, shipped tracked from the UK.

Our commitment

We test hardware the way it will actually be used: a full cooling cycle, a full battery cycle, and a seal check before anything is packed. If a unit drifts outside its stated window it does not ship. If you want the detail behind a specific test, our team will walk you through it.
