Density: ~0.34 g/mL (free fall density)
General description: Porapak porous polymer materials are spherical beads with consistent particle size, porosity, and surface area that help to insure analytical precision and accuracy.

Other Notes: The optimal temperature for Porapak porous polymer materials depends on the application. For example, thermal desorption unit (TDU) tubes are typically desorbed at 180 °C, and GC column applications may work best with final oven temperatures of 30-190 °C.
