We have developed a cost effective screening process to identify or confirm the absence of the impurities listed in the ZDHC MRSL 1.1.

In order for the results to be meaningful and to ensure that they accurately represent the product you place on the market, we recommend a minimum of 3 samples from different batches should be tested.

Discounts are available if more samples are commissioned at the same time or if ongoing batch testing is required.
