More than 3000 scientists are making routine work out of surface chemistry, corrosion, magnetic susceptibility and TGA with CAHN Recording Balances.
So w h y are you still frustrated? Continuous recording of weight changes as small as 0.1 microgram. In inure than UOOO laboratories m o u n d 1h.fi world, Cnhn recording balances are making routine w o r k out of i n v e s t i g a t i o n s a n d m e a s u r e m e n t s o n c e considered impractical, cumbursume, expensive and ill" doubtful accuracy. They product; more m(!;i!iiiigful dala, mure accurate in weigh! values, and wilh sharper résolu I ion. The instruments are so ru^-jL'd and d e p e n d a b l e and results so reprod u c i b l e , l h a l e x p e r i m e n t s c:an p r o g r e s s u n a t tended, freeing the researcher fur other work. Vacuum Slandard models for work down to JO " Ion-, with special HV and UfiV models for even hiyher vacuums. Controlled atmospheres -lise in any a t m o s p h e r e your rescrinih requires. Special accessories and lccliuii|ues permit use of corrosive Rases. Temperature—Maximum sample l e m p e r a l u r c unlimited. No minimum tempera!uro limit. Surface C h e m i s t r y - Cahn Recoidint; Balances are llie only production balances with increased sensitivity, stability and precision compared to the unwieldy and exasperating h o m e m a d e ap-
