British Pharmacopoeia Chemical reference substances (BPCRS)

These Primary standards are established using absolute methods and the declared content figures are determined without comparing to another substance. You should use BPCRS to perform the tests in the British Pharmacopoeia (BP) or BP (Veterinary). Do not eat BPCRS or feed them to animals – you should only use BPCRS for chemical analysis. They are not suitable for any other use.

We are pleased to update that products affected by the recent electrical freezer fault are now available following their temporary withdrawal.

This follows a detailed quality assessment of vialled stock and re-vialing product from our reserved bulk supplies.

Thank you again for your patience while we worked to resolve this matter.
