Catalog details infrared sampling accessories. 58 New R C L Automatic Sample Changer provides higher efficiency of windowless gas flow detection without contaminating the counting chamber — and a faster counting rate. New design features unique prc-flush chamber ahead of the counting chamber and a four-position precision geneva movement sample changer. Counting column holds 50 samples in pans up to 1 l/i" diameter. Samples automatically (or manually) advance to preflush chamber, where counting gas atmosphere flushes out normal air contamination. Samples then enter counting c h a m b e r under positive pressure which prevents contamination from the pre-flushing chamber. C o n t i n u o u s flow of c o u n t i n g gas over samples permits instantaneous reading. When changer is combined with R C L Printing Sealer-Timer, Model 20318, the count can be automatically recorded. Output can be routed to digital tape printer, x-y curve plotter, nixie display or almost any other readout or printout device.

Since 1954 N a t i o n a l A p p l i a n c e has maintained pioneer leadership in the development of controlled environment chambers for use in life science studies. With the recent introduction of two new units, a reach-in chamber (No. 6500) and a walk-in chamber (No. 6 5 6 0 ) , a demand for simplicity, flexibility and economy in this type of equipment has been met. These chambers are aimed at a multitude of uses where strict reproduction of phenotypical characteristics or close control and measurement of environmental variables is essential. Despite their economy (prices start at $2995.00), the new chambers meet the following standards required of all National apparatus:
