Malvern Zetasizer Nano ZS
Malvern Zetasizer combined 3 major techniques:
1. Dynamic Light Scattering for Particle Size measurement
2. Static Light Scattering for Mw measurement
3. Zeta-potential measurement
Equipped with MPT-2 autotitrator and temperature control system, the Zetasizer Nano is capable for pH titration, sample dilution and injection, temperature trend measurements and melting point studies.

Important Notification:
* (2022-08-10) Zetasizer is out of order. Sorry for inconvenience.
* (2010-04-02) Cuvettes should be rinsed and sonicated in your buffers and/or ddH2O before applying samples for measurements.
* (2009-09-02) Please avoid dusts or contaminate when preparing your sample. Do not transfer samples from container to container, which introduces dusts and bubbles.
