Premium UK Research Peptides
Pure compounds. Hard data.
We don't deal in claims. We deal in chromatography. Independent researchers and clinical institutions trust Purivo Biolabs for the highest purity UK research peptides, backed by accessible, lot-specific analysis.
01 The standard
Every lot is accounted for, crimp to dispatch.
A reseller can print a purity figure. What they cannot show you is where a specific vial came from, when it was made, and how it was held since. Purivo keeps that record against the batch code, and hands it to you with the order.
Synthesis logged
Manufacturing origin and synthesis date are recorded for the lot, not the product line.
Four assays, then quarantine or pass
Purity, identity, water and endotoxin are measured before stock. Any lot out of specification is held back, not sold.
Secure storage
Held securely in our UK facility. Handling is recorded so there is no import step or customs hold on your order.
Shipped with its certificate
The vial leaves with the certificate for that exact batch, securely packaged, the next working day.
02 What we measure
Four tests decide whether a batch is released.
We publish the chromatogram rather than a single number, because the shape of the impurity profile is what tells you whether a lot is usable for your assay. A summary figure hides it.
- Purity
- 99.2%
- Identity
- Confirmed
Reversed-phase HPLC
Purity is reported as percentage peak area, with the release specification stated per product. The measured figure for your lot appears on its certificate.
C18 · 0.1% TFA / MeCN gradient · 214 nm detection
Mass spectrometry
Electrospray ionisation confirms the observed molecular mass against the theoretical mass for the sequence. Identity is a pass or a fail, never an estimate.
ESI-MS · observed vs theoretical monoisotopic mass
Karl Fischer titration
Residual water in the lyophilised cake. High water shortens shelf life and skews the mass you weigh out, so it is measured rather than assumed.
Coulometric titration · % residual water
LAL assay
Limulus amoebocyte lysate, reported in endotoxin units per milligram. Relevant wherever contamination would confound a cell-based result.
LAL · endotoxin units per milligram
03 Traceability
Enter a batch code. Read its certificate.
The code is on the vial label and the outer carton. This is the record no reseller can reproduce, because it is generated per lot and archived, not written on a listing.

04 Catalogue
The Clinical Inventory. Curated for institutional rigor.
The range is defined by what laboratories characterise and study, not by consumer demand. Each line is supplied lyophilised, sealed under inert gas, with a colour-coded cap that reads the reference from any angle in a rack.
All products are supplied with their batch-specific HPLC and MS analytical certificates.
05 Bulk Procurement
Wholesale & Institutional Accounts
While independent researchers can purchase directly from our catalogue, verified businesses and academic institutions can apply for a B2B account to unlock bulk tier-pricing and direct wire transfer capability.
Submit your details
Provide your institution or business name, along with the principal investigator or R&D lead.
Account verification
Our team will verify your institutional status. Academic, corporate, and clinical domains are fast-tracked.
Unlock bulk pricing
Access our wholesale rate card for volume orders. Significant discounts apply for 100+ vial procurements.
Direct procurement
Pay via secure bank transfer or standing order. All consignments ship securely the next working day.
Our position
Purivo supplies laboratory reagents to independent researchers and institutions. Our materials are not medicinal products, not supplements, and are strictly not supplied for administration to humans or animals. We make no therapeutic claim and publish no dosing guidelines.
This is the whole of our position, and it is not negotiable.
All supplies are strictly for in-vitro research purposes.
