For Analytical Chemistry

---

For Analytical Chemistry the future of turbo design begins here. More tnan half of the turbomolecular pumps operating today are built by Balzers, producing the cleanest, most convenient and powerful vacuum systems possible. The Tirst turbo pump, developed for our customers 30 years ago, introduced this technique for producing low pressures down to ultra-high vacuum. Since then, the hydrocarbon-free turbo concept has helped turn a multitude of sophisticated technologies into routine procedures. Today turbo designs are smaller, lighter and more efficient than ever—producing vacuums from 1 torrto 1 χ 10-11 torr. Plus, they're available in a variety of sizes and types to meet your specific applications. Our streamlined, air-cooled designs are perfect for gas analysis, load locks and small process systems. Our low vibration pumps provide stable operation for sen­ sitive equipment such as electron micro­ scopes. Other designs are ideal for SIMS, AUGER, ESCA, GCMS, LCMS and other analytical techniques.

As a result of our quest to achieve opti­ mum size/performance ratios, Balzers designed the first turbomolecular pump compact and rugged enough for use in outer space. Meanwhile, here on earth, Balzers continues to expand horizons in performance and reliability for you.
