Density Determination - Sartorius LA Reference Series Operating Instructions Manual

Density Determination

Purpose
With this application you can determine
the density and volume of solid, pasty,
liquid or powdered samples.
You can use the "Density Determination"
application in combination with
a program chosen from Application 2
(e.g., checkweighing, timer functions)
and one from Application 3 (totalizing,
formulation, statistics) as well as the
extra functions.
E
Available Features
– Choose from 2 methods for determining
density of solids:
– Buoyancy, or
Wa
– displacement.
Wa
– Density determination on pasty
or powdered samples using the pyc-
nometer method
Wfl Wa
– Density determination on liquids using
the liquid density method
– Choice of liquids for buoyancy:
– Water
– Ethanol
– Other liquids (user-definable)
– Reference values can be entered using
the numeric keys
– Weight of sample in air (Wa)
– Weight of sample in liquid, or weight
of reference liquid when using the
pycnometer (Wfl)
– Weight of sample and reference
liquid when using the pycnometer (Wr)
– Long-term storage of parameters:
– Temperature
– Buoyancy correction
– Air density
– Density of reference liquid
– Expansion coefficient
– Plummet volume
