Gammadot
has taken delivery of a Reologica AB ViscoTech controlled stress
/ rate rotational rheometer from Infra Scientific Ltd, Reologica's
UK distributor. The ViscoTech is an accurate, easy-to-operate
benchtop instrument, which couples a low position resolution
with a wide torque & temperature range, giving a machine
with the ability to characterise a variety of materials ranging
from low viscosity fluids to highly viscous semi-solids. Test
programmes cover steady shear, transient (creep / stress relaxation)
and periodic (dynamic oscillation) modes providing the ability
to fingerprint both a material's flow & structural properties.
Said
Mark Edwards, Gammadot's principal, "The addition of the
ViscoTech compliments the currently used StressTech HR, (Reologica's
research grade rheometer), and with both systems equipped with
plate / plate, cone & plate and coaxial cylinder geometries,
we are able to offer an extremely flexible rheological measurement
service to industry".
Gammadot
offers comprehensive rheological and materials characterisation
support to the plastics and rubber industries.
Services cover the application of rheology to quality control,
failure analysis and process optimisation issues, to providing
accurate materials property data (viscosity, PvT and thermals)
for flow simulation software packages such as Moldflow and Sigmasoft
3D.
In addition to being sole UK distributor of the
Reologica range of industrial and research rheometers, Infra
Scientific Ltd
has a long history with particle sizing / characterisation and
now acts as a UK / Eire distributor for a number of other companies,
including Occhio image analysis, and the incredible value for
money laser diffraction and image analysis equipment from Bettersize
in China. In addition to selling the instrumentation a full
contract testing service is offered on all sizing / imaging
instruments.
In
2003 Infra Scientific produced the Visco Lite micro capillary
viscometer aimed at ultra low viscosity measurement (ink jet
printer inks, dilute polymer solutions, dilute aqueous solutions,
organic solvents, hydrocarbons, biofluids, etc). The Visco Lite
is the only viscometer capable of measuring from 0.1 mPas to
20 mPas with 0.02 mPas accuracy. More
