Dispersion Characterization instrumentation available | Malvern Zetasizer Nano | | | Features: | - Malvern patented NIBS optics allows measurements of samples with little or no dilution
- Uses a unique disposable zeta potential cell to ensure no cross contamination of samples
- Can analyze liquid
- Particle size reported on intensity and volume basis
- Zeta Potential in aqueous and non-aqueous fluids
| | Applications: | - Particle Size - measurements of particle size from 0.6nm - 6µm
- Zeta Potential - measurements
| | Recommendations for Optimal Output: | | - Viscosity of carrier fluid at desired analytical temperature (If not known default values will be used.)
- Dielectric constant of carrier fluid (applicable for Zeta Potential)
- Refractive Index and imaginary number (can analyze without)
- Recommended amount of sample needed: 3-20 mL
| | Brookfield LVDV-II+Pro Viscometer | | | Features: | | - Dynamic Viscosity measurement of liquids and colloidal suspensions
- Simultaneously measures sample viscosity, temperature, shear rate/stress, percent torque, and rotational speed
| | | Applications: | | - Viscosity range: 1cP - 1,000,000 cP (mPa s)
- Shear rates: up to about 100 sec-1
| | | Recommendations for Optimal Output: | | - Sample amount for expected viscosity < 10cP = 15mL
- Sample amount for expected viscosity > 10cP = 200-400mL
- Specific temperature at which you would like the measurement taken
- Newtonian or non-Newtonian sample designation
