Bettersizer 2600

1. Fourier and Inverse Fourier Optical System 

The Bettersizer 2600 is superior in the combination of Fourier and inverse Fourier designs. This smart design allows, on the one hand, the detection of scattered light in a very wide angular range from 0.016° to 165°. On the other hand, in contrast to the inverse Fourier design, the particles do not have to lie on one plane – the simultaneously accurate measurement of small and large particles is therefore achieved.

Features of the combination of Fourier and inverse Fourier design 

• Spherical detector array: Forward, lateral and backward detectors in 92 pieces in total; 
• Super large Fourier lens; 
• Small footprint: Compact design to save space.

2. Intuitive and Powerful Software 

• Intuitive user interface and orderly operation
• Real-time PSD curve for determining the optimal measurement conditions 
• Fully automatic measurement routine 
• Automatic cleaning routine 
• Automatic data backup and highly customizable reports 
• Direct conversion according to Fraunhofer and Mie evaluation models 
• Switch between wet and dry dispersion modules with one click

3. Wet Dispersion 

BT-802 is designed for particle size measurement with water as the medium. 

BT-802 is made up of an ABS shell. The components of it include a centrifugal pump, a peristaltic pump, an ultrasonic disperser, pinch valves, a control circuit, etc. The stirring speed is adjustable from 300 - 2500 r/min. The built-in ultrasonic system (50 W) helps weak agglomerates separate.

 

 

BT-80N is designed for particle size measurements with organic solvents as the media. BT-80N is suitable for common organic solvents, for example:

Ethanol	Methanol	Isopropanol	Ether
Toluene	Xylene	Dichloromethane	Octane
Ethyl acetate	Acetone	Methyl oleate	NMP solvents

BT-80N is made up of stainless steel shell. The components of it include a centrifugal pump, an ultrasonic disperser, a PTFE pipeline, a sintered-quartz sample cell, a control circuit, etc.

 

BT-804 is designed for valuable or small-volume sample measurements, where the medium is solvent or water. The module consists of an ABS shell, a stirring motor, a cuvette (8 ml), a stirrer, etc. 

• Maximum volume in 8 mL with samples mass in 0.005 - 0.1 g. 
• Suitable for samples dispersed in water or organic phase.

 

4. Dry Dispersion 

BT-902 is suitable for dry powder measurements. The gas used can be compressed air, nitrogen or other noble gases.
BT-902 is made up of an electromagnetic vibration feeder, a venturi pipe, a gas circuit, an electric circuit, a pressure sensor, etc.

BT-903 is designed for particle size measurements of valuable and small amounts of dry powders with a minimum sample volume of 20 mg.

BT-903 is composed of a venturi pipe, a gas circuit, an electric circuit, a sample tube, etc.

5. Applications 

1) Standard Operating Procedure (SOP)

SOP is an easy solution for standardized and automatic testing, which ensures the measurement results operator-independent, making the results more objective and reliable.

2) Advantages

• The Bettersizer 2600 offers an easy solution for standardized and automatic testing.
• It ensures that the measurement results are operator-independent, more objective, and reliable.

High Resolution and Sensitivity

The resolution and sensitivity of Bettersizer 2600 as verified below: sample A was gradually added to sample B, and the graph changed correspondingly.

Sample A < Sample B

Sample A = Sample B

Laser Diffraction

The particle size distribution is a crucial parameter in many applications that involve powders or dispersions. These include construction materials like cement and sand, pharmaceuticals, ceramics, colored pigments, fertilizers, emulsions, and more. As the range of applications expands, so do the requirements for measuring methods in terms of size range, measurement time, and reproducibility.

Measuring particles close to the range limits and simultaneously detecting particle sizes of both small (nanometer range) and large particles (lower millimeter range) for polymodally or broadly distributed samples is particularly challenging. However, modern laser diffraction particle size analyzers such as the Bettersizer S3 Plus overcome these challenges through innovative optical system design that detects backscattered light of very small particles and captures large particles with an integrated high-speed CCD camera or a combination of laser diffraction method and image analysis method.
