Features and Benefits

Dual Lens Optical System (DLOS)

The Bettersizer ST features the patented Dual Lens Optical System (DLOS) that enables it to quantify a broad range of continuous particle sizes without any compromise.

The forward, lateral, and backscatter laser diffraction pattern is detected by the DLOS. The DLOS is an innovative technology that leads to an increased particle size measurement range without the additional cost of a second light source. This single laser design provides for higher accuracy due to a consistent wavelength throughout the full measurement range.

Automatic Test

The SOP of Bettersizer ST offers an intuitive solution for automatic and standardized testing. With just a single mouse click, 'Auto Test' starts auto-alignment, quantifies the background, alerts the operator to add the sample and subsequently quantifies and prints out the result without any more intervention.

Efficient Wet Dispersion System

The Bettersizer ST has a centrifugal pump that serves as the main element in an extremely efficient dispersion system. This system ensures quick and reproducible dispersion of samples. Before performing a test, the pump starts an automated sequence that prevents bubbles which otherwise can adversely affect results.

Rugged and Compact Design

The Bettersizer ST incorporates a solid-state laser diode that offers long life while preventing laborious instrument warm-ups. The compact footprint of the ST frees up precious workspace.
