Conclusions:
A pycnometer was used for the determination of the density and relative density of Hepteen Base®.
The density of the test item at 20ºC was 0.912 g/cm3 (0.912 x 103 kg/m3).
The relative density was 0.912.
Executive summary:

A study using apycnometerwas conducted to determine the density/relative density ofHepteen Base®. The experiment was conducted in accordance with the following guidelines in a GLP accredited laboratory.
