NANO-flex® II

The NANO-flex® II is a second generation nanoparticle measurement system for particle size distribution with 180° Dynamic Light Scattering (DLS).

The nanoparticle measurement system is designed for the characterisation of dispersions and colloids in the size range of 0.3 nm to 10 µm. Depending on the sample, it is possible to measure very low concentrations (0.01%), up to as high as 40% w/v. The NANO-flex® II is a stand-alone particle size analyser that can also work in conjunction with the Stabino® system for simultaneous size distribution, zeta potential and titration/stability measurements.

As the exclusive distributor for the UK and Ireland, Analytik is proud to supply the NANO-flex® II from Colloid Metrix. Through Analytik, you’ll have access to our team of experts to help develop your application and get the most out of your investment.

Description

Particle Size Distributions

The NANO-flex® II 180° DLS system measures size distributions in the range of 0.3 nm to 10 µm.

The unique 180° back scattering principle of the Nanotrac® allows measurement of highly concentrated samples, without interference from the effect of multiple scattering. The heterodyne design of the NANO-flex probe means that some reference light from the laser is reflected straight to the detector to act as a reference and significantly improves the signal-to-noise ratio of the NANO-flex compared to other DLS instruments.

The NANO-flex® is designed as a flexible measuring probe with 8mm diameter. It can therefore be used for a whole range of in-situ particle sizing scenarios, whatever the vessel – be it 96 well plates, beakers, vials or even in the Stabino zeta potential titration beaker for simultaneous size and charge experiments.

Key Benefits:

  • 180° heterodyne dynamic light scattering (very short light path in the sample avoiding multiple light scattering).
  • Measurement in a variable concentration range (0.01 up to 40% w/v) from 0.3nm to 10um particle size.
  • Dip in probe offering online in-situ size measurements
  • Solvent resistance
  • Usable in combination with Stabino® for simultaneous size, zeta potential and titration/stability measurements

In-line ApplicationsThe NANO-flex pressure measurement cell

The NANO-flex can also be used for in-line applications, such as during a milling process. The IPAS accessory allows the NANO-flex to take accurate size measurements either during a process flow or in a stirred beaker, by isolating a small sub-volume of sample for measurement, before releasing it back into line, in a completely automated solution.

DLS Applications

DLS applications with the NANO-flex® nanoparticle measurement system module are almost unlimited, provided the viscosity of the sample is in the Newtonian range, a condition for the free Brownian movement in the fluid and for the accurate calculation of size. The liquid medium of the particles can be of organic or aqueous nature. The critical coagulation point of a dispersion can be determined by measurement of size and potential with the Stabino®.
