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.

Dear valued customer,
We are writing to let you know that, due to an electrical fault, our freezers in which some BPCRS vial stock was stored switched off for a short period and the storage temperature may have been compromised over the weekend of 21st/22nd June. This was detected promptly and rectified, but as a precaution we have removed all affected items from sale and are conducting thorough testing to verify their stability and usability.
Consequently, you may notice in the short term that a higher number of products than usual are showing as “out of stock”. This process is necessary to ensure that only products that meet our quality standards are shipped to you.
We sincerely apologise for any inconvenience and appreciate your patience and understanding, and would like to reassure you that;
· None of the affected vials have been shipped to customers.
· All affected vials have been quarantined.
· We are urgently reviewing the material stability data and carrying out testing to determine if the material has been affected.
· We have additional bulk supplies of the materials which have not been affected and we can produce more vials from these bulks.
Products will be brought back into stock as soon as we can confirm they have not been affected. As we assess the products and gather more data we will be able to update with estimated timeframes in due course. As soon as we have further information we will update this page.
