Frequently asked questions

Every item listed on this website is supplied exclusively for laboratory research. Nothing we sell is a medicinal product, a food, a cosmetic or a medical device, and nothing we sell may be administered to humans or animals or used for diagnostic purposes. By ordering, you confirm you are a qualified researcher or are purchasing on behalf of a research institution, laboratory or business.

Accounts are opened for individuals aged 18 or over who are qualified researchers, and for institutions, laboratories and businesses purchasing for research. We are not able to supply members of the general public. We may ask for institutional details or a business registration before releasing a first order.

Each lot is analysed by an independent laboratory using reverse phase HPLC with diode array detection, alongside LC-MS identity confirmation, an endotoxin screen and a heavy metal screen. The certificate records the method, the column, the detection wavelength, the date of analysis and the report number, and it is published against the lot number.

In stock orders placed before 2pm on a working day leave our Northampton facility the same day on a tracked service. Tracked UK delivery is £5.95, and delivery is free on orders over £120 excluding VAT.

Lyophilised material should be stored sealed, in the dark, at minus 20 degrees Celsius. Storage and handling guidance is enclosed with every order and is available on the storage and handling page. We do not publish preparation, reconstitution or usage guidance of any kind.
