Equipment 8 piece(s)

Simultaneous Thermal Analysis (TGA/DSC)
STA 409 PC

Generally used in materials characterization to provide heat capacity data as well as temperature information such as inset temperature, melting point, and glass transition. This model allows for simultaneous collection of thermal gravimetric data, allowing correlation of mass and energy data from one instrument.

  • The carbide furnace chamber is purged with N2 to provide an inert atmosphere and avoiding combustion.
  • Temperature range of room temperature to 1500 Celsius. 
  • Ramp rates are generally between 5-20 K/min.
  • Sample size is generally ~20 mg.

Inductively-Coupled Plasma Optical Emission Spectrometer (ICP-OES)
Perkin Elmer
Optima 8000

Simultaneous analysis of up to 60 elements in nitric acid. Can be used both in both axial and radial modes to increase sensitivity and detection.

Note: This instrument is designated as a non-HF instrument. 

Wet Dispersion Particle Size Analyser (PSA)
Mastersizer 3000

To analyse particle size of solids suspended in a liquid medium, using dynamic light scattering.

Particle range between 0.01 - 3500 micron.

Agilent Technologies

Precise mechanical testing with force and displacement, with measurement of deformation her six orders of magnitude (nm - mm). Generally used for Young's Modulus and hardness testing. 

  • <0.01 nm displacement resolution
  • > 500 micron max indentation depth
  • 150 micron indenter travel
  • Max load: 500 mN

Helium Pycnometer
AccuPyc II 1340

Generates pore volume and density values for powder samples.

  • Sample chamber: 10 cm3
  • Reproducibility typically to within ± 0.01% of the nominal full-scale sample cell chamber volume., However; reproducibility guaranteed to within ± 0.02% of the nominal full-scale volume on clean, dry, thermally equilibrated sample using helium in the 15 to 35 C range.
  • Accurate to within 0.03% of reading, plus 0.03% of sample capacity.

Mechanical Testing (Bose)
Electroforce 3510

Single column electromagnetic mechanical testing. Capable of performing tension, compression, fatigue, stress, strain, dynamic materials analysis and applying waveforms to sample. 

  • Load Capacity: +/- 1275 kg (12.5 kN)
  • Displacement Capacity: +/- 25 mm (total range of 50 mm moving both plates)
  • Maximum test space height 1000 mm
  • Test space width: 558 mm

Mechanical Testing (Instron)

Single column force transducer for tension and/or compression tests

  • Capacity: 2000N, or ~ 200kg
  • 1067 mm in vertical test space

High Temperature Furnace
RHF 16/3

High temperature alumina furnace (3L volume) used for the preparation of glasses.

Samples quickly and can reach max set point in under one hour.

  • Max temperature 100 degrees below max temperature. Therefore, this furnace can be used to 1500 Celsius.
  • Internal Dimensions (H  W x D in mm): 120 x 120 x 205
