Laser Particle Size Analyzer (Wet and Dry Dual-Use) DRK-G300

DRK-G300 Laser Particle Size Analyzer (Wet and Dry Dual-Use)

DRK-G300 Laser Particle Size Analyzer (Wet and Dry Dual-Use) is an all-round particle size analysis instrument. This instrument adopts a split design, with the sampler and the main unit separated. It supports wet and dry detection dispersion methods, enabling more convenient mode expansion and conversion. Thanks to its plug-in pipeline design, switching the detection method can be achieved by simply matching the corresponding sampler and detection window. Additionally, micro-volume, large-capacity, or corrosion-resistant sampling systems can be selected as accessories.

DRK-G300 laser particle size analyzer is based on the full-range Mie scattering theory. Its design fully complies with ISO international technical standards. Structurally, it uses a pure helium-neon gas light source and a large-angle, non-uniform, crossed, fan-shaped, super-large detector array. This design takes full account of the detection angle and sensitivity, ensuring a wide testing range as well as the accuracy and repeatability of the test results.

Wet Dispersion

The ultrasonic dispersion system of the DRK-G300 laser particle size analyzer can fully disperse the sample to be tested. The high-power ultrasonic generator (100W) is equipped with a dry-running protection design. The ultrasonic time can be adjusted automatically and continuously. Users can set it according to the difficulty of sample dispersion. With good shielding, ultrasonic dispersion and sample testing can be carried out simultaneously. Even particles with strong agglomeration can be fully dispersed, enabling the acquisition of real particle size distribution data.

The sample dispersion cell is made of stainless steel. It has a unique circular design, facilitating liquid circulation and drainage. The micro-arc design prevents dirt accumulation, making it easy to clean, and it is also equipped with a liquid level protection device.

The wet dispersion method has automated functions such as automatic water inlet, automatic testing, automatic optical path status determination, automatic bubble elimination, and automatic cleaning. Liquids like distilled water, pure water, and alcohol can be used as the dispersion medium.

Circulation Stirring System

Select an appropriate circulation stirring speed according to the characteristics of the sample to be tested to prevent particle sedimentation in the circulation pipeline. The circulation pump speed can be adjusted automatically and continuously, with a digital display for settings. When the ultrasonic function is turned on during the testing process, it can avoid testing errors caused by bubbles generated due to excessive circulation speed and prevent particle agglomeration during the circulation process.

Dry Dispersion

The sample is evenly conveyed into the high-pressure airflow through the automatic dry powder sampler. Driven by the high-pressure airflow, it is continuously and rapidly sprayed into the disperser. By the time it reaches the outlet of the disperser, the sample has been fully dispersed. After passing through the laser beam, the sample enters the collector or vacuum cleaner, and the particle size distribution information is immediately displayed on the computer.

1. For dry dispersion, no dispersant or solvent is required. The dispersion principle is shown in the following figure.

1. It uses a silent, oil-free air compressor, paired with an efficient condenser to ensure the production of pure compressed air.
2. It enables instantaneous dispersion and measurement, with high testing accuracy and fast analysis efficiency. The process from sample injection to result output is completed instantaneously.
3. It has automatic sample injection and supports fully automatic one-key operation.
4. The unique duck-bill-shaped nozzle significantly improves the detection stability and accuracy.
