The NEW Model 364 Polarographic Analyzer...
. . . everything you ever wanted in a low-cost instrument - a t less!!!
Î
A L L YOU EVER WANTED
MORE FOR LESS
Y O U asked for a versatile teaching tool, so we b u i l t in dc, sampled dc, normal pulse, and d i f f e r e n t i a l pulse capability.
We t h i n k y o u w i l l agree t h a t the new Model 364 is a lot o f i n s t r u m e n t f o r $ 1 , 1 9 5 . N o w , at m i n i m u m cost, y o u can put as m a n y 364's as y o u need int o y o u r undergraduate labs and i n t r o duce all the students t o the concepts o f polarography and stripping v o l t a m m e t r y . Y o u can teach t h e m the techniques that are so w i d e l y used for p p m - and ppb-level analyses o f metals, organics and anions.
Y O U requested operational simplicity, so we f i x e d the values o f clock rate, m o d u l a t i o n a m p l i t u d e and o u t p u t filtering. Y O U needed an instrument layout optimized for teaching purposes, so we p u t all the inputs and o u t p u t s o n the f r o n t panel. Y O U bad t o have trace analysis capability, so we designed the 364 f o r ppblevcl sensitivity t o y i e l d large, noisefree peaks. Y O U required an i n s t r u m e n t t h a t could stand up to the rigors of an undergraduate lab, so we made the 364 rugged and " s t u d e n t - p r o o f " . Y O U insisted on the lowest possible price, so we set it at $ 1 , 1 9 5 .
T o get y o u started w i t h a m i n i m u m o f fuss and bother w e include w i t h every 3 6 4 one copy o f a laboratory manual i n c o r p o r a t i n g our application and technical notes. A d d i t i o n a l manuals are available at low cost.
As an educator y o u w i l l appreciate the Model 364's a b i l i t y to be used w i t h a w i d e variety o f e l e c t r o d e s d r o p p i n g m e r c u r y , hanging m e r c u r y d r o p , g o l d , p l a t i n u m , glassy carbon or wax-impregnated graphite. Y o u w i l l also be glad t o k n o w t h a t we stock a f u l l line o f electrochemical accessories, including cells, electrodes, hardware, kits and recorders.
