Guideline:

other: Inernal SOP (G03302) Specific gravity and density at 25 °C (by pycnometer)

GLP compliance:

no

Type of method:

pycnometer method

Type:

density

Density:

0.923 g/cm³

Temp.:

25 °C

Results

Wt. Pyknometer                     :          45.360 g

Wt. Pyknometer + water         :          145.330 g

Wt. Pyknometer + samples    :          137.884 g

 

Specific gravity = (137.884 – 45.360)           = 0.925

                          (145.330 – 45.360)

 

Density @ 25 °C = 0.925 x 0.9971 (density of water at 25 °C) = 0.923 g/mL
