Service & Technical Points
What is Rheology ?Rheology is the science of flow and deformation of matter.The relationship between stress and deformation is a property of the material. We can therefore define Rheology as the study of stress-deformation relationships.
What is a Rheometer?
An instrument that measures both viscosity and viscoelasticity of fluids, semi-solids and solids
It provides following information about the material’s:
Viscosity (which is the function of shear rate or stress, time & temperature dependence)
Viscoelastic properties (G’, G”, tan d) with respect to time, temperature, frequency & stress/strain
Transient response (relaxation modulus, creep compliance, creep recovery)

Thermal Analysis techniques are applicable to most material
classes. Some of the more common classes include :
DSC: Differential Scanning Calorimtery
TGA: Thermo Gravimetric Analyzer
SDT: Simultaneous Differential Thermal Analyzer
DMA: Dynamic Mechanical Analyzer
TMA: Thermo Mechanical Analyzer
DSC - What can it measure?
Q 2000 is top-of-the-line, research grade with all options
Q 200 is research grade and expandable
Q 20 is a basic DSC
Q2000 DSC:Auto samplerModulated DSCAdvanced Tzero capability (T4P Heat flow signal).User replaceable Cell Pressure DSC cell option Q200 DSC:Autosampler is optional Tzero heat flow correction option (T4) for improved transition resolution and baseline flatness.MDSC is an option with maximum heating rates of 5C/Minute available.Q20 DSC:Q20 It is an Entry level DSC which does not have the T Zero heat flow corrections for improved resolution and baseline flatness.

AVAILABLE MODEL FOR TGAs
THE HIGHLY AUTOMATED Q5000 IR OFFERS UNMATCHED BASELINE FLATNESS, HIGH SENSITIVITY, ACCURATE TEMPERATURE MEASUREMENT, AND PRECISE CONTROL IN
BOTH STANDARD AND HIGH HEATING RATE OPERATION. OTHER GREAT FEATURES INCLUDE VACUUM OPERATION, AUTOMATED CURIE POINT TEMPERATURE CALIBRATION, POWERFUL NEW SOFTWARE AND A 25-POSITION, SMART AUTOSAMPLER WITH A UNIQUE CONTAMINATION-FREE, SEALED PAN PUNCHING MECHANISM. IT IS CLEARLY THE BEST ANALYZER FOR COMPLEX TGA APPLICATIONS.
TGA Q 500
The Q500 is a research grade thermo gravimetricanalyzer, whose leading performance arises from aresponsive low-mass furnace; sensitive thermo balance, and efficient horizontal purge gas system (with massflow control). Its convenience, expandability and powerful, results-oriented software make the Q500perfect for the multi-user laboratory where a wide varietyof TGA applications are conducted and where futureexpansion of analytical work is anticipated
The easy-to-use Q50 is a rugged, reliable, cost-effective TGA with many features of the Q500. It offers outstanding value as a compact, general-purpose thermo gravimetric analyzer that frequently outperforms competitive research-grade models. Its integral mass flow control, gas switching capability, and superb software make the Q50 ideal for academic teaching facilities or in industrial laboratories that need quality results at a modest cost.
