ELSZ-2000ZS Particle size, zeta potential, molecular weight analyzer


In addition to existing zeta potential and particle size measurement, molecular weight analysis function is newly added.


Electro-osmosis measurement enables high precision analysis of zeta potential using micro-volume(130μl) disposable cell.

 

New auto temperature gradient function with extended range between 0 and 90℃ makes melting point and phase transition point analysis possible.
