	RCA EMU-2E This electron microscope was produced by RCA (Radio Corporation of America) in the mid 1950s. It was operated at 50 Kev and initially purchased by the Department of Microbiology, University of Georgia. It was transferred to the Department of Geology, and in 1981 was placed in Gainesville Junior College. The microscope was returned "home" to Athens in 1985. RCA guaranteed a resolution of better than 100 Å, but 20 Å was obtained on some of the instruments.		Balzers Minature Coating Unit, Micro BA3 Manufactured in 1966, the instrument was purchased by the Department of Microbiology, UGA. The coating unit was used to carbon coat and shadow specimens for the TEM. The coating unit has a mechanical fore pump and a "2" inch diffusion pump, air-cooled.
	JEM 30 Electron Microscope Purchased originally in 1965 from Fisher Scientific by Dr. Hope Ritter, Univ. of Buffalo, the scope was moved to the Department of Zoology, UGA in 1966, when Dr. Ritter took a position here. Interesting features: - Accelerating voltage: 30 Kev - Column at 30 degree angle - Fixed magnification screen for 2K, 3K and 4K. Total Mag of 30,000 with a special accessory plate (magnifying lens) for a 35mm camera - Microscope operated on 115 volt a/c line - Rotary mechanical and oil diffusion pumped - Resolution of 100 Å - Cost: $6,300		Porter-Blum MT-1 Microtome Purchased by the Dept. of Microbiology, UGA, Serial #127, built in the 1950's. The microtome featured a mechanical advance cutting arm. The microtome was developed in part by the noted Dr. Keith Porter and was sold under the Sorvall trademark of the Ivan Sorvall Co., NY, NY.
	Knife-making Instruments The Glazer's pliers were used to fracture glass to produce knives for cutting specimens. Plate glass was precisely scored with the glass cutter and then fractured with the pliers. Old storefront glass was choice glass because it had "settled" to produce a hard, dense glass.		Phillips EM-75 Manufactured in 1963 and purchased by the Department of Geology, UGA. Interesting features: - Magnification range, 1,200 - 12,000, magnification was accomplished by moving the projector lens up and down on the beam axis - An accessory was a low voltage anode so that the microscope could be operated at 15 Kev - Single condenser lens - Resolution of 15 Å - Glass diffusion pump - First solid-state instrument sold
	Siemans ELMISKOP 1-A Manufactured in Berlin, Germany in 1963 and purchased by the Medical College of Georgia, Department of Anatomy. The microscope was in continuous use until 1986. Interesting features: - Double condenser - Selectable 40-60-80-100 Kev accelerating voltage - Magnification 200 - 192,000 - Working resolution - 60 Å theoretical - 2.8 Å - Glass negative plates
