5 new spectrophotometers from Zeiss. Count 'em. 5! The new PM 6 line of s p e c t r o p h o t o m e t e r s has four different models. All w i t h doubleg r a t i n g m o n o c h r o m a t o r s . All w i t h a u t o m a t i c blank reference. One of t h e m certain to fit your needs. Consider now the single-package PM 6's. So c o m p a c t , each takes up less t h a n 2 ft. 2 of bench space. S a m p l i n g capabilities range f r o m m a n u a l to fully a u t o m a t i c , and all c a n be equipped w i t h recorders or p r i n t e r s . Ideal for e n d p o i n t and kinetic m e a s u r e m e n t s . All four PM 6's house D e u t e r i u m and Halogen light sources ( a n d t h e i r power sup plies, too) for efficient coverage f r o m 2 0 0 to 8 0 0 n m . All use wide-range p h o t o m u l t i p l i e r s and. w i t h their double-grating m o n o c h r o m a tors, have t h e lowest stray-light levels of any
s p e c t r o p h o t o m e t e r s in their price class. The highly accurate a n d reproducible measure ments are displayed in absorbance and con centration units o n a 4-digit readout. Operation is simple and foolproof. Truly human-engineered with few controls f o r rapid, error-free p e r f o r m a n c e . And t h e advanced i n tegrated c i r c u i t r y makes the i n s t r u m e n t s prac tically service-free.
LOW-PRICED WORKHORSE PM-2: Priced at around $2600. Because some labs don't need the many capabilities built into PM-6's (at $4000-$8000), but do want the same Zeiss pre cision and ease of operation, we're introducing the PM-2. A precision-grating instrument ideal for clinical use with auto matic blank reference. For UV and visible.
