Used a Weinmann prisma before?
Then you already know these machines. Weinmann Geräte für Medizin, which made the original prisma range, was renamed Löwenstein Medical Technology in 2016 after the Löwenstein Group acquired it. The prisma 25ST, prisma 30ST and prisma VENT sold today are the same line, now under the Löwenstein Medical name.
