Our Mission

Committed to Excellence

We believe that quality research begins with quality materials. Every product we offer reflects our commitment to advancing science.

Quality First

Every compound undergoes rigorous testing to ensure purity and consistency before reaching your lab.

Technical Support

Our dedicated team is available to answer questions about compound specifications, COA documentation, and product selection.

Transparent

We provide detailed certificates of analysis and maintain complete transparency about our products.

How we verify

Purity You Can Verify

Not every compound clears the AION standard. We test through Freedom Diagnostics, USA, with independent Certificates of Analysis tied to the product and lot. — HPLC purity, LC-MS identity and net content, as reported on each lot’s Certificate of Analysis.

Verification goes beyond a purity number — with HPLC purity, LC-MS identity and net content, as reported on each lot’s Certificate of Analysis

01

The lab has a name

Every published Aionsci certificate identifies the independent laboratory behind the analysis. No anonymous reports. No mystery testing.

02

Match the lot on your vial to the certificate

Batch-level, not brand-level. The lot number printed on your Aionsci vial should correspond to its published Certificate of Analysis. Your vial. Your lot. Your data.

03

Measured, not claimed

We don’t want “99%+ purity” to be just something printed on a label.

Your Questions
Our Answers

No marketing fluff. Real answers to the questions PIs and lab managers actually email us before placing an order.

1 What does “≥99% HPLC verified” actually mean?

Every batch is analysed by reverse-phase HPLC at an independent, ISO/IEC 17025-accredited laboratory. A batch is only released when the main peak accounts for at least 99% of the total signal, and that result is printed on its certificate.

2 Are Aionsci pens intended for human use?

No. Aionsci pens are supplied strictly for laboratory research use. They are not medicines and are not for human or veterinary use, or for the diagnosis, treatment, cure or prevention of any condition.

3 How do I find the COA for my pen?

Every pen label carries a batch number. Look it up in the COA Library, or open the product page: the certificate for each strength is linked there and can be downloaded as a PDF.

4 How are pens packaged and shipped?

Each pen is sealed, capped and colour-coded, then packed in a protective box together with its batch documentation. Every order ships with tracking, and we email you the tracking number.

5 How long does a sealed pen keep?

A sealed pen keeps its stated quality until the date printed on its label when it is stored at 2–8°C, upright, capped and protected from light. Do not freeze.
