When selecting your new Centrifuge—consider:

Centrifuges of Proven Performance

1 The reliabil ity of the electric m o t o r tha t drives i t . The motors of International Size 1 and Size 2 Centrifuges are specially designed to provide the best possible drive for a Laboratory Centrifuge. They are manufactured entirely in our own shops, thus eliminating the possibility of obso­lescence through discontinuance by an "outs ide" manu­facturer.

2 T h e r a n g e of i t s appl icat ion . Interchangeable accessories designed specifically for Inter­national Centrifuges are available in wide variety, making the machines adaptable to practically every laboratory appli­cation. Your future requirements as well as your present needs should be considered.

3 T h e r e l a t i o n of first cos t to to ta l cos t . Expensive repairs can make a low first cost a high cost in the long run. International Centrifuges are famous for their ability to give years of trouble-free service.

4 The reputat ion of the manufac turer . International 's fifty years of specialization in the manufac­ture of L a b o r a t o r y Cent r i fuges is your guarantee of unequalled performance.
