ViscometerViscometer

iVisc is an automated viscosity measuring instrument for fluids, based on drag caused by relative motion of the fluid and a surface.  It is based on U-tube capillary viscometers or Ostwald viscometers made of a U-shaped glass tube with two marks (one above and one below the bulb) is held vertically in a controlled temperature bath.  Main application: molecular weight determination of synthetic polymers.
 



Thermal Gravimetric Analysis (TGA)Thermal Gravimetric Analysis (TGA)

TGA measures amount and rate of weight change vs. temperature or time in a controlled atmosphere. It is used to determine composition and thermal stability of polymers and composite materials. The measurement can be conducted at the temperature from ambient up to 1000 °C, under purge gases of nitrogen or air.

 

 

Dynamic Mechanical Analyzer  Dynamic Mechanical Analyzer

Q 800 Dynamic Mechanical analyzer DMA (TA Instruments) measures the mechanical properties of solid polymer samples with different parameters: temperature, time, frequency, force or strain; measurement of storage and loss modulus, Tg and other transitions.
 

 

 

RheometerRheometer

ARES1500 rheometer measures viscoelastic properties of polymer solutions (semiditluted concentration range) under oscillation test. It measures viscosity as a function of shear rate or stress, time and temperature dependence, storage modulus (G’) Loss Modulus (G”) with respect to time, temperature,
frequency and stress/ strain.
