MANS STEREOSCOPIC DISSECTING MICROSCOPE -- Die Wirtschaft, No it, 26 Jan 50
The people-owned Carl Zeiss plant in Jena has developed a new stereo-
scopic dissecting microscope, the Citoplast. The instrument is for use in
micro experiments requiring constant changes in degree of magnification. An
adjuster makes it possible to vary the magnification from four power to 1(Y^
power without time-consuming change of lenses. A strong floodlight is used
to illuminate the subjects. The operating distance is 100 millimeters for
all degrees of magnification.
The Zeiss plant has also produced valuable attachments for the Zeiss-
Pulfrich photometer, one of which is a combination opacity and fluorescence
meter which makes it possible to make nephelometric determinations on col-
loid solutions, to observe and measure opacity reactions over a period of
time, to make fluorometric determinations of concentration, and to measure
the fluorescence of liquids.
Another interesting development is the Zeiss flame photometer, a photo-
electric instrument used by agricultural specialists to determine the press
ence and concentration of potassium, calcium, and sodium. Its advantages
over chemical analysis are the speed of determination and the very small
amount of substance required. Concentrations of one milligram per liter
can be measured with this instrument.
The people-owned Filmosto Projector Plant has produced a new and im-
proved enlarger for miniature films, Autofoc II. It has an autonv tic fo-
cusing device and additional. possibilities for manual focusing when the lens
mounting and lamp box are moved. The instrument can be used for 24 x 36-
millimeter to it x 4-centimeter film.

Phonetika, one of the factories included in the Association of People-
Crwnsd Radio Equipment Lhterprises, is scheduled to triple its 1949 production
in 1950. The plant, located in Berlin-Weissensee, produces radios and radio
tubes, as well as machines for the manufacture of tubes and electric-light
bulbs. In the future, Phonetika will also manufacture transmitter and vacuum
tubes. Production of primary receivers will be increased.
