Glass Frit Impinger DUSA

Used as an alternative to the DUSA after proper equivalence testing (ask us how!). Used by many of the leading companies within OINDP testing. This filter comes in various forms but adheres to the principles which was published in a USP stimuli article 1993. 1  It lends itself to high-capacity testing and automation since it is washable with good recovery and minor carry-over.
