In dynamic production environments and research centers, efficiency and flexibility are among the most important criteria when choosing analytical equipment. Most laboratories work with a wide variety of materials - from fine suspensions and emulsions to dry, loose and agglomerating powders. The Bettersizer 2600 was created for this versatile environment. It is a modular laser diffraction analyzer that allows you to perform the highest precision measurements in one device, regardless of the sample's state of aggregation or its chemical properties. Thanks to its smart design, this device is characterized by exceptional resistance to difficult operating conditions and guarantees long-term operation.
Modular architecture for wet and dry dispersion
One of the biggest innovations of the Bettersizer 2600 is the quick-change dispersion module system. This concept allows laboratories to avoid purchasing two separate devices. Depending on the specifics of the material being tested, the operator can change from a wet dispersion module to a dry dispersion system in less than a minute. The wet station is equipped with a high-performance centrifugal pump and a powerful ultrasonic probe that effectively disperses particles that are difficult to dissolve in water or organic solvents. Meanwhile, the dry dispersion module uses compressed air flow and Venturi nozzle technology that separates powder particles extremely gently but effectively without damaging their primary structure. This is critical when testing fragile materials, such as active pharmaceutical ingredients or loose powders.
Advanced optical system and measurement accuracy
Behind the device’s performance lies a sophisticated, combined Fourier and inverse Fourier optical system. The Bettersizer 2600 uses a powerful laser source and places detectors not only on the front, but also on the sides and back. A total of 92 large-area detectors are installed, covering measurement angles from 0.016° to as much as 165°. This unique spherical detector array guarantees unprecedented sensitivity when measuring the smallest particles, while maintaining the ability to accurately capture macro-level objects. Thanks to such an optical architecture, the analyzer reliably covers the measurement range from 0.02 μm to 2600 μm. It is important to note that the entire optical system is enclosed in a hermetic housing, so the lenses remain protected from dust, moisture and ambient temperature fluctuations, which directly determines the durability of the device in industrial conditions.
Innovative refractive index measurement
When performing laser diffraction measurements based on the Mie scattering theory, it is necessary to know the refractive index of the material under study precisely. Traditionally, this parameter is searched in databases or guessed, which can lead to significant errors, especially when analyzing new, not yet described materials or mixtures. The Bettersizer 2600 solves this problem with a unique integrated refractive index measurement function. Before starting the main analysis, the instrument can automatically measure the actual refractive index of the sample and use this data to calculate the particle size distribution. This eliminates any assumptions and ensures that the results obtained are absolutely accurate and scientifically sound.
Software and standardized work
Like other top-of-the-line Bettersize models, this analyzer is equipped with intuitive and powerful software that allows you to automate all processes. Laboratory managers especially appreciate the ability to create standard operating procedures (SOPs). The user can create individual profiles for different products, specifying air pressure (for dry measurement), pump speed, ultrasound time and calculation models. In the daily routine, the operator only needs to insert the sample and press a single button - the equipment does everything automatically. This ensures ideal measurement reproducibility, meeting the requirements of the ISO 13320 standard, and eliminates the possibility of human error.
Wide application possibilities
„The Bettersizer 2600 is one of the most popular devices in the world due to its price-performance ratio. In the building materials sector, it is an indispensable tool for cement plants, assessing grinding efficiency and cement hydration properties. In the chemical and paint industries, it guarantees pigment uniformity, which determines the coverage and color brightness of paints. The device is also widely used in metallurgical research, in the food industry, for testing starch or flour, and in agriculture. It is an investment in peace of mind and guaranteed product quality, regardless of the industry in which your company operates.
