IL-IS Distribution Service




Our IL-IS distribution service was transferred to a web-based version. In the web-shop, you can create your own account in the context of other users within your institution. After logging-in, you can place your order directly on the website. Therefore, the e-mail service ILIS@cvuas.bwl.de is not to be used for orders any more. It can still be used for general questions regarding IL-IS purchases!

The web-shop is available here: https://perchlophos.eu/

The conditions of sale remain the same.

Important: Please solely use our web-shop for orders! Orders placed solely via e-mail will not be processed any more!

Conditions of sale

For ordering, create an account in our web-shop and place your order online:


Only orders placed in the web-shop will be accepted!

The standards are shipped once a week (on Tuesdays or Wednesdays).


Please note:

The isotopically labelled standards are produced in our lab within the frame of our duties as EU-reference laboratory (as described in Reg. 882/2004/EC). The general aim is to improve the analytical capability especially of official laboratories in the analysis of these specific compounds. The standards are offered on non-profit basis.

For that reason we aren’t able to fulfill special requests.

You can find our bank transfer data using this Link.




Please note that complaints on shipment can only be considered within 14 days after receipt of the invoice. 

If you have any questions please don’t hesitate to contact us via ILIS@cvuas.bwl.de
