In Pharmaceutical industries, hygienic regulations surely number among the most important, and they require the use of rupture discs combining top performance – such as vacuum resistance and sensibility to extremely low pressures – with the possibility of total cleaning and disinfection, and with compatibility with the fields' omnipresent CLAMP attachments.

DonadonSDD's ideal product for this application surely is the NS NANOSCORED rupture discs for sanitary applications series; such discs are only scored on the discharge side, and they have a smooth surface which is easy to clean ( both in C.I.P. and S.I.P. situations), on the process side. They are vacuum resistant with no need for supports, even for non-PED applications, and they are equipped with CLAMP gaskets certified according to FDA and USP class VI regulations.
