02/06Inside the laboratory

Where every Zynox vial begins.

A glimpse of the UK facility where our peptides are synthesized, HPLC-verified, and lyophilised before they reach the bench. Every step is traceable, every batch independently tested.

03/06Research categories

Find the right tool for your laboratory.

Eight research categories, twenty-three products, all batch-tested. Every category page surfaces molecular data, storage and reconstitution guidance.
04/06The Zynox standard

Built for the lab,
not the gym bag.

Three commitments that define every batch we synthesize, label, and dispatch. We answer to researchers, not influencers.
05/06From bench to bench

Every vial passes through
four checkpoints.

A traceable chain of custody from synthesis through quality control and lyophilisation to discreet, tracked dispatch.
01

Solid-phase synthesis

Fmoc chemistry on automated SPPS systems. Crude peptides are then purified by reverse-phase HPLC.

SPPS · Fmoc
02

Quality control

Each batch verified by analytical HPLC and mass spectrometry. Purity must exceed 99% before lot release.

>99% verified
03

Lyophilisation & vialing

Controlled-vacuum lyophilisation, clean-room vialing, individually labelled with sequence, lot and expiry.

Tracked dispatch

Temperature-stable foil packaging, plain discreet outer, tracked from the UK within 24 hours.

The HPLC traces matched the COA peak-for-peak. Reconstitution behaviour was identical between two separate lots — that consistency is rare in this market.

The packaging is genuinely clinical — foil-lined, plain outer. We have shipped these to three different European universities without a single integrity issue.

Customer service responded within an hour with the COA for an unusual lot reference. That is the kind of accountability we expect of a research-grade supplier.
