The Lightnin SSi (stainless-steel inline; photo) and SSO (stainless-steel offset) mixers use high-efficiency gearing to match individual application needs and are specifically designed to meet the high standards required by the pharmaceutical, biotechnology and food-and-beverage industries. The mixers are suitable for a wide range of mixing applications in areas including buffer and media preparation, fermenters, bioreactors, product recovery and bulk pharmaceutical processing. Their hygienic design offers either USP Class VI or FDA GRAS elastomers and seal faces. The mixers have open-tank, lip-seal and mechanical-seal mounting options with a choice of ANSI, DIN or sanitary flanges. The units are further designed to accommodate longer shaft lengths to fit mix-tanks without the need for any in-tank bottom support. This makes the units easier to maintain and operate without the possibility of damage to the mixer or tank. Various motor options, plus a full spectrum of impeller types, are available to meet a wide range of tank sizes. — SPX Flow, Inc., Charlotte, N.C.
