The Beckman Multisizer™ 4 is one of the most versatile and accurate particle size and particle counter analyzers on the market today.

Beckman Multisizer™ 4 - Electrical Sensing Zone

The Beckman Multisizer™ 4 utilizes the coulter principle or Electric Sensing Zone (ESZ). This method allows the Beckman Multisizer™ 4 to return distributions of number, volume and surface area in a single measurement.
The Beckman Multisizer™ 4 has an overall size range of 0.4 μm to 1600 μm. This response is not affected by particle shape composition, refractive index or color.

The Coulter principle is the leading technology for high resolution and high precision. The Beckman Coulter Multisizer™ 4 further enhances this through the use of a Digital Pulse Processor (DDP). DDP offers ultra-high resolution, multi-channel analysis and precision unattainable by other similar technologies. These features make the Beckman Multisizer™ 4 ideal for any research project involving sizing and counting.

Multisizer™ 4 is an equally powerful quality control tool. Analysts now have a highly advanced, easy-to-use system that can resolve most particle size problems. The Beckman Multisizer™ 4 is the latest coulter counter designed with Smart and DDP technology to provide highly reliable and accurate particle counting and grading.

The Beckman Coulter Multisizer™ 4 retains the enhanced analog circuitry developed and refined by Beckman Coulter over the years. The Beckman Coulter Multisizer™ 3 introduces DPP to particle counting for the first time.

Beckman Multisizer™ 4 - Digital Principles Coulter integrates the latest advances in analog and digital circuitry. High-speed digitization of the signal enables more accurate particle characterization using multiple parameters. Beckman Multisizer™ 4 now enables dynamic dimensioning. Measurements for each particle are analyzed and stored; the stored data can then be analyzed and formatted in a variety of ways. Stored data can also be reanalyzed at a later date. With the Beckman Coulter Multisizer™ 4, there is no need to analyze the same particle twice.
