Digital Density Meter DMA4500

4 Digit Density, Specific Gravity and, Concentration Meter
Measuring range: 0 - 3 g/cm^3, 0 - 90 degC, Accuracy: ±5x10-5g/cm3, ±0.03℃、Repeatability ±1x10-5g/cm3、±0.01℃
This instrument is used for accurate measurements of solvent viscosities necessary for contrast-variation SANS. Precise density measurements will also be done for water-soluble polymer solutions having a LCST for understanding hydrophobic interaction.

Digital Microscope VHX-900

This digital microscope is a versatile microscope with a built-in light source that can be handled without the microscope stand. One of the major characteristics is its long depth of filed of the order of 30 times longer than conventional optical microscopes, which makes it easy to measure the size of gel in a temperature- or pressure-cell and to observe the surface pattern on a gel. The magnification covers from 35x to 1000x.

Static/Dynamic Light Scattering (ALV-5000) DLS1

Multi-purpose DLS. Molecular dynamics in solutions, gels, and melts can be studied. He-Ne laser.

Static/Dynamic Light Scattering (ALV-5000) DLS2)

DLS for special environments, such as High-pressure, High-temperature, and UV-irradiating DLS experiments. The photo shows High-pressure DLS setup.

Static/Dynamic Light Scattering (ALV-5000) DLS2

Setup for UV-irradiating DLS experiments. UV light is shed from the downstream. Laser light from the upperstream is scattered by the sample and the scattering intensity is observed at 90 degrees through a UV-cut filter.

Static/Dynamic Light Scattering (ALV-5000) DLS3

Advanced DLS/SLS instrument for fast dynamics.

Differential Scanning Calorimeter (DSC8230)

Enthalpy change in various transitions, such as in melting and phase transition, can be evaluated.

Rheometer (Anton Paar、MCR501)

The velocity of the rotor is controlled with an air bearing. Cone plate, parallel plate, and quartz cell for SANS, are available.

Inverted Optical Microscope (TM-300, Nikon)

Inverted optical microscope (TM-300, Nikon) with image processor (Algas 2000, Hamamatsu Photonics) for swelling/shrinking measurements.

Polarized Microscope (Olympus)

Poralized microscope (Olympus) with image acquisition sytems.

Differential Refractometer

Differential refractometer (Photal) for dn/dc measurements.

Dynamic Mechanical Analysis Instrument (UBM)

DMA instrument to measure viscoelactic properties of solid-like polymer during oscillating motion.

Karl-Fischer Titrator (Metrohm)

Karl-Fischer titrator for water content measurement of ppm order.

Heat-Pressing Machine

Heat-pressing machine to shape resin samples, such as Bakelite.

  • Two dimensional SANS Instrument (SANS-U)
  • Neutron Spin Echo Spectrometer (iNSE)

Two dimensional SANS Instrument (SANS-U)

Shibayama Lab. is in charge of SANS-U. It has been used for structural investigations on soft matter, biological systems, and hard matter, for more than 15 years.

Neutron Spin Echo Spectrometer (iNSE)

This iNSE has the finest energy resolution as a quasi-elastic neutron scattering spectrometers.
Dynamics on polymers, gels, micelles, and emulsions. with a few to tens nm size and time-scales of a few ns can be investigated.
