]]> Titanium dioxide particles have excellent optical properties and allow low doping of your sample for a given turbidity. For improved dispersibility, the TiO2particles are coated with silica. The particles come in powder form and are thus easy to add. Due to the significant particle density, TiO2 particles are most appropriate for samples with high viscosity or highly structured samples.

The post Polystyrene particles appeared first on LS Instruments Shop.

]]> For aqueous samples, polystyrene particles are often the best choice. LS Instruments offers monodisperse spherical polystyrene particles specially designed for DWS applications. In particular, the batch does not contain surfactant traces (in contrast to most other suppliers) that could contaminate your sample.

mean diameter 460 nm, depending on the batch (hydrodynamic size, measured by DLS and SLS)
PDI <0.11 (PDI=‹d2›/‹d›2
zeta potential -80±10 mV (Smoluchowski approximation, in 10 mM phosphate buffer)
specific gravity 1.05
solvent distilled water

The particles are synthesized without surfactant to protect your sample against contamination. The production of the DWS tracer particles is outsourced, hence the average size and concentration may differ from batch to batch. Each batch is characterized separately.

10 mL with 8.3 wt.% particle concentration: 210 CHF (excel. shipping cost and taxes that may apply)

Square cuvettes for SLS/DLS

CHF391.00 excluding VAT

SLS and DLS measurements on highly turbid samples are possible using a 3D LS Spectrometer equipped with the option “sample goniometer”.

12 in stock

SKU: CUV014 Categories: ,

SLS and DLS measurements on highly turbid samples are possible using a 3D LS Spectrometer equipped with the option "sample goniometer". Using this configuration, the light scattering experiment is performed close to the corner of a square cell, thus reducing the laser path length through the sample down to 0.2 mm.

We can recommend the use of Hellma square cell cuvettes as specified below. You can order them directly at your local distributor of Hellma (ordering number 111-10-40, type 111-QS) or at LSi.

  • Reference: CUV/009
