equipment— offering the flexibility you must have for research applications as w e l l as t h e s p e e d a n d c o n v e n i e n c e y o u need for production work. MEETS VARIED REQUIREMENTS OF RESEARCH
P r o v i d i n g a r e a d y m e a n s of p e r f o r m i n g a n y studies at reduced pressures or in special atmospheres, the RCA Vacuum Unit gives t h e research scientist a truly flexible tool to meet a variety of vacuum problems. It may also be used for "shadowing" specimens for light and electron microscopy. APPLIES COATING WITH PRODUCTION SPEED
The RCA Vacuum Unit combines operating speed (only 7 minutes to 0.1 micron Hg) with electro-magnetic valving which eliminates heating and cooling delays of thermal pumps —perm i t s i m m e d i a t e r e o p e n i n g , fast r e c y c l i n g . Completely interlocked for safety and equipped with 3 pairs of filament supports and an eighteen-inch bell-jar, the RCA Vacuum Unit is widely used for coating lenses, crystals, and plastics. AVAILABLE FROM STOCK
RCA Vacuum Units are quantity produced for stock, eliminating the delays normally associated with custom-built equipment. NATION-WIDE SERVICE
