Fat and Crude Fiber Determinations Made EASY With t h e apparatus pictured above, you save t i m e when r u n n i n g large n u m b e r s of fat extractions and crude fiber d e t e r m i n a t i o n s . The 6-unit "Goldfisch" Extractor (left) and the Crude Fiber Condenser (right) are m o u n t e d o n a 10' χ 2' 6" table m a d e of steel and treated asbestos. Both apparatus are wellWrite
known for speed and efficiency, and used in t h e lab oratories of leading industrial concerns and univer sities the world over. Note t h e special table fittings t h a t speed fiber determinations—shelves, burette rods for dispensing solutions, lead drain, water and v a c u u m connections, fully controlled flush-mounted h o t plate.

the new Coleman
PHOTO-NEPHELOMETER
MODEL
SEVEN
This new instrument for Nephelometric analysis, together with the associated Coleman Nephelometric Standards, offers scientists for the first time a practical and rational means for expressing haze in terms of a coherent numerical system. Instead of the great amount of time required by gravi metric analyses, only seconds are required to quantitatively measure precipitates with the Coleman Photo-Nephelometer. Results are exactly reproducible, interprétable between different laboratories and at different times. The instrument is extremely sensitive, making it possible to evaluate solutions whose solid concentration is so low that the haze is hardly discernible to the eye. For further information regarding this new instrument for a new field of science, write for Bulletin No. 213-B. An authorized Coleman Dealer.
