Product Description

Brief introduction

Bettersize2000B is an intelligent particle size analyzer that adopts 400nm short wavelength laser as light source. Its outstanding features are that lower limit of test can reach to 0.01μm, and has particular functions of auto test, auto alignment, auto water supply, auto bubble removal, auto cleaning, etc. As adopting high precision battery of lens, the system has features of clear imaging and low phase difference distortion, ensures that weak scattered light signals produced by particles in submicron, even in nanometer can be received effectively. It adopts anti-dry dispersing technology, when turn on ultrasonic, circulation tank will not be damaged without water. The instrument has the characteristics of good accuracy and reliability, good repeatability, easy operating, fast test speed etc., which is especially suited to mixed sample in micron and nanometer.

Good repeatability

Has stable and reliable laser device, detector and signal transmission system.
Stable and effective dispersing system.
Automatic alignment system keeps the instrument always in optimum condition.
Sampling rate can reach 3500 times/second, and mass data can effectively reduce the influence of small amount of abnormal data on repeatability.
As adopting the high precision battery of lens, the system has clear imaging and low distortion, ensuring that weak and scattered light signals from all angles can be detected completely.


Kindly reminder:
Repeatability is primary index of a particle size analyzer. It is worthless for a particle size analyzer if repeatability is not good. Repeatability is related to the instrument, also, related to the operator, voltage, water quality and  interference. It is a reflection of composite factors.

Good accuracy
1. Reasons for good accuracy:

Adopts dual lens optical system developed by Bettersize, and quality composite lens, which improves the precision of measurement greatly.

Adopts blue light laser that wave length is 405nm, plus high performance software, so accurate test result can be obtained no matter the it is a single peak, double-peak or nanoparticles sample.

Complete sample preparation system is comprised of circulation, ultrasonic dispersion, stir, auto water supply, auto drainage and auto cleaning.

Use standard sample to verify, and result is identical with nominal value.

2. Test results of standard sample in nanometer: Deviation between test result and nominal value is very small.
