You can download our annual PDF programme for 2026 here and send us your registration by email 
or register directly via our Shop button on top of this page and get a 5% discount per ≥ 10 registrations until the 31th of January 2026.

The registration process for our Proficiency Tests is now simplified and even more flexible: From now on, multiple PTs can be booked in a single order and optional choices such as for allergen screenings (participation with one method or participation with 2 to 3 methods) as well as the possibility of ordering duplicate sample material are taken into account. 
Using the quote function, you can first generate a quote and later add your PO number when placing the final order.

Even as a new customer or if you do not have a customer account so far, you can still visit our webshop. If you would like to place an order afterwards, you can create an account using the ‘Apply for an account’ button.
