Differential Scanning Calorimeter (DSC)
TA Instruments
Q20P
  • DSC is a thermal analysis technique that looks at how a material’s heat capacity (Cp) is changed by temperature. A sample of known mass is heated or cooled and the changes in its heat capacity are tracked as changes in the heat flow. This allows the detection of transitions such as melts, glass transitions, phase changes, and curing.
  • The Q20P is a dedicated pressure DSC system that provides heat flow measurements on pressure sensitive materials from -130 to 550 ˚C, at pressures from 1 Pa (0.01 torr) to 7 MPa (1,000 psi).
  • Sample size 0.5 to 100 mg (nominal)
  • Sample volume 10 mm3 in hermetic pans
  • Sample pans Various open or hermetically sealed (standard and Tzero series)
  • Purge gases Recommended: air, argon, helium, nitrogen, or oxygen
  • Typical purge flow rate 50 mL/min
  • Cell volume 3.4 mL

Dynamic Mechanical Analyzer (DMA)
TA Instruments
Q800
  • DMA measures the mechanical properties of materials as a function of time, temperature, and frequency. 
  • The Q800 utilizes state-of-the-art, non-contact, linear drive technology to provide precise control of stress, and air bearings for low friction support. Strain is measured using optical encoder technology that provides unmatched sensitivity and resolution. 
  • The Q800 offers all the major deformation modes required to characterize solid bars, elastomers, soft foams, thin films and fibers. The deformation modes include bending (single cantilever, dual cantilever, and 3-point bend), shear, compression, and tension. In addition, submersible compression and film tension clamps are available.

Co-rotating twin-screw kneader
Collin
ZK 25(42 D)

The twin-screw kneaders have the task of conveying, compacting, plastifying and homogenizing plastics materials (in granule and powder form), fed via a hopper/dosing unit, and to feed these to a die (mould) for further forming.

The twin-screw kneader serves to manufacture test specimens and to evaluate the material processing properties.

DPN is NanoInk's patented process for deposition of nanoscale materials onto a substrate. The vehicle for deposition can include pyramidal scanning probe microscope tips, hollow tips, and even tips on electronically actuated cantilevers.

DPN is an established method of nanofabrication based on atomic force microscope (AFM). It enables precise control of the materials transferred from a tip to a substrate.

Custom-designed nanoscale features are easily fabricated using “ink" comprised of a wide range of materials from nanoparticles and thiols to DNA and proteins.
