Verification standard

The Synthesis-to-Shipment Journey.

Peptide stability and purity are highly sensitive. We protect the integrity of your laboratory research through rigorous, continuous controls at every phase.

Synthesis & Batching

01

Precision synthesis under certified laboratory conditions, ensuring exact peptide chain sequencing.

Dual HPLC & MS Validation

02

Every batch is analysed via Chromatography and Mass Spectrometry. We only accept 99%+ purity.

Cryogenic Storage

03

Lyophilised vials are instantly stored at -20°C in our facility to preserve structural integrity.

Discreet Same-Day Dispatch

04

Each order is sealed in discreet, protective packaging and dispatched same-day before 2pm, with tracked UK delivery.

Reconstitution

Plan your reconstitution before you open the vial.

Working out the concentration and dilution volume for lyophilised peptides is central to reproducible research. Use our interactive mini calculator to plan your stock concentration in mg/ml before you reconstitute.

Kovalabs supplies reference chemicals for laboratory assessment only. Work out the dilution here first, so the concentration in the vial is a number you set rather than one you discover later.
