  Title: STS-34 middeck experiment Polymer Morphology (PM) apparatus without cover
  Description:
  STS-34 middeck experiment Polymer Morphology (PM) apparatus is documented
  in  a table top view with outer cover or housing removed.  Carousel and
  sample  cells are visible. PM, a 3M-developed organic materials processing 
  experiment, is designed to explore the effects of microgravity on polymeric 
  materials as they are processed in space.  The samples of polymeric
  materials  being studied in the PM experiment are thin films (25 microns or
  less)  approximately 25mm in diameter.  The samples are mounted between two
  infrared  transparent windows in a specially designed infrared cell that
  provides the  capability of thermally processing the samples to 200 degrees
  Celsius with a  high degree of thermal control.  The samples are mounted on
  a carousel that  allows them to be positioned, one at a time, in the
  infrared beam where  spectra may be acquired.  The Generic Electronics
  Module (GEM) provides all  carousel and sample cell control.  The first
  flight of PM will contain 17  samples.  PM experiment is being conducted by
  3M's Space Research and  Applications Laboratory.
