Core com­pe­tence: Our pro­duc­tion ran­ge inclu­des a wide varie­ty of cer­ti­fied refe­rence mate­ri­als, spe­cial stan­dards and con­trol milks. We car­ry out qua­li­ty assuran­ce pro­fi­ci­en­cy tests for dai­ries and labo­ra­to­ries. Extern­al­ly and intern­al­ly com­mis­sio­ned con­sul­ting, rese­arch and deve­lo­p­ment pro­jects and par­ti­ci­pa­ti­on in natio­nal and inter­na­tio­nal working groups stand for our competences.
