Density Determination - Sartorius la 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 (totali-
zing, formulation, statistics) as well as
the extra functions.
Available Features
E
– Choose from 2 methods for
determining density of solids:
– Buoyancy, or
Wa
– displacement.
Wa
– Density determination on pasty
or powdered samples using the
pycnometer method
Wfl
– 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
