The Bettersizer S3 Plus combines laser diffraction and dynamic image analysis in one instrument. It can measure the size and shape of particles from 0.01 μm to 3500 μm. Its exceptional sensitivity for either ultrafine particles or oversized particles, and unsurpassed resolution, make it the most powerful size and shape analyzer for enthusiastic researchers who conduct top scientific research.
Features and Benefits
-
● Measuring range is 0.01 - 3,500μm (laser system), 2 - 3,500μm (image system)
-
● Combining laser diffraction and dynamic image analysis in one instrument, obtaining size and shape results simultaneously
-
● Patented DLOI (Dual Lenses & Oblique Incidence) system enable the measurement of ultrafine particles down to 0.01 um
-
● Dual-camera imaging technology can show particles images in real time and detect oversized particles up to 3500 um
-
● Refractive index measurement determines the refractive index of unknown samples and improves te reliability of results
-
● Compliance with 21 CFR Part 11, ISO 13320, USP <429>, CE
1) High Resolution and Sensitivity
The Bettersizer S3 Plus achieves exceptional resolution and sensitivity for particle size measurements. The DLOI system allows the size distributions of polydisperse samples to be determined precisely, and the size changes of products to be detected sensitively.
2) Multiple Shape Parameters
An example of additive manufacturing for shape analysis using the Bettersizer S3 Plus is shown below. A representative number of individual particles are recorded from two AlSi10Mg samples, and the number-weighted aspect ratio and circularity are evaluated in compliance with ISO standards. (Adapted from F. Schleife, C. Oetzel. Chem. Ing. Tech. 93.8 (2021): 1199–1203.)
3) Oversized Particle Detection
Laser diffraction in combination with image analysis can sensitively detect oversized particles that are statistically underrepresented within a wide-distributed sample, such as oversized grains, agglomerates, air bubbles, etc. An example of an off-specification abrasive is displayed below. The Bettersizer S3 Plus confirms the presence of oversized particles, by showing a size peak at around 120 μm and the images of overly coarse particles.
4) Analysis of Samples with Extremely Broad Distributions
