Food Ingredients and Additives [DM40] [RM40] [Color] [pH] [LabX]
Specic gravity and refractive index
are the two key parameters in the
quality control of food additives.
Manufacturers of avors increas-
ingly also systematically determine
pH and color. LiquiPhysics™ Excel-
lence offers all the tools required
to set up fully automatic measur-
ing systems which can cope with
many parameters per sample and
many samples per day with inclusive automatic barcode reading
and data export.

Cosmetics [DM45] [RM40] [Color] [pH]
Density meters, refractometers, pH
meters and colorimeters are essential elements of the standard
equipment of most cosmetics labs.
These instruments are used for a
wide range of applications. Density
determinations to comply with the
ll-volume ordinance and combined specic gravity refractive
index measurements to ensure that
fragrances are perfectly composed
are only two examples of many
tasks LiquiPhysics™ Excellence can
assume in the cosmetics lab.

Pharma [DM45] [RM40] [Color] [pH] [LabX]
Specic gravity and refractive index determinations are among the
simplest and fastest methods to
characterize liquid samples. Moreover, these two parameters are
becoming more and more popular
for concentration determinations
in binary mixtures. The pH value
trol of pharmaceutical solutions.
LiquiPhysics™ Excellence covers all
these applications. With the LabX™
Laboratory Software it provides the
tools required to ensure all results
are traceable and comply with the
strict regulations governing the
pharmaceutical industry.

Education & Government [DM45] [RM40]
High precision density meters are
the appropriate tools to detect two
popular tricks to evade taxes: Fuel
adulteration and fake alcohol con-
centration declarations. With the
DeltaRange™ density measuring
cells, LiquiPhysics™ Excellence offers the accuracy required for these
applications at best value prices.
Almost every educational lab is
equipped with at least one refractometer although many of them are
still optical Abbé type refractome-
ters. LiquiPhysics™ Excellence pro-
vides state-of-the-art replacements
for such instruments.

Biofuel [DM45] [RM40] [Color] [LabX]
LiquiPhysics™ Excellence covers
several of the core parameters determined in the quality control of
biofuel: Density of bioethanol and
biodiesel, ASTM color of biodiesel
and the density and refractive index
of Glycerol. At the same time, it offers the possibility of performing
quick and reliable quality control
checks of the liquid raw materials
used in the production of biodiesel.

Petrochemistry [DM40] [RM40] [Color]
Most petrochemical products are
liquid at ambient temperature. Density and its industry specic unit
API gravity have always been important parameters for the classi-
cation and characterization of petrochemical products even for those
which are highly viscous or solid
at room temperature. LiquiPhysics™
Excellence offers ideal solutions
for a large variety of petrochemical
products thanks to wide measuring temperature ranges, very quick
heating up- and cooling down
rates, automatic viscosity correc-
tion, whole temperature range adjustments and powerful automation units which are also available
as heated versions. Furthermore,
LiquiPhysics™ Excellence allows the
determination of several param-
eters in one run. For instance, measuring density at 15 °C, refractive
index at 20 °C and ASTM color of
lubricants is a matter of one single
click.
