Digital Density Meter DMA4500

Digital Microscope VHX-900

 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.
