Brief Introduction
The Bettersize 2000B is an advanced intelligent particle size analyzer that utilizes a 405nm short-wavelength laser as its light source. This device is designed to deliver exceptional performance, with a lower detection limit of 0.01μm and a wide range of automated functions such as auto testing, auto alignment, auto water supply, bubble removal, and cleaning. The system is equipped with high-precision optical lenses, ensuring clear imaging and minimal phase distortion, which allows for the effective detection of weak scattered light signals from submicron and even nanoscale particles. Its anti-dry dispersing technology prevents damage to the circulation tank when using ultrasonic power without water. With features like high accuracy, excellent repeatability, ease of use, and fast testing speed, the Bettersize 2000B is ideal for analyzing mixed samples in both micrometer and nanometer ranges.

Good Repeatability
The Bettersize 2000B ensures stable and reliable performance through its high-quality laser, detector, and signal transmission system. It also features a robust dispersing system that maintains consistent sample preparation. The automatic alignment function keeps the instrument in optimal condition at all times. With a sampling rate of up to 3,500 times per second, the system effectively minimizes the impact of small anomalies on repeatability. The high-precision lens assembly ensures clear imaging and low distortion, allowing for complete detection of weak and scattered light signals from all angles.
Kindly Reminder: Repeatability is one of the most important indicators of a particle size analyzer. If it's not good, the instrument loses its value. Repeatability depends not only on the equipment but also on the operator, voltage stability, water quality, and external interference. It is a reflection of multiple factors working together.
Excellent Accuracy
1. Reasons for high accuracy:
- Utilizes a dual-lens optical system developed by Bettersize, combined with high-quality composite lenses, significantly improving measurement precision.
- Equipped with a blue light laser (405nm) and advanced software, enabling accurate results regardless of whether the sample has a single peak, double peak, or is composed of nanoparticles.
- Features a comprehensive sample preparation system including circulation, ultrasonic dispersion, stirring, automatic water supply, drainage, and cleaning.
- Verified using standard samples, with results matching nominal values precisely.
2. Test results for nanometer-scale standard samples show minimal deviation from expected values.
