Beckman Coulter Multisizer 4e Aperture-Based Particle Size Analyzer with 70 µm Aperture

The Beckman Coulter Multisizer 4e Particle Sizer is a benchtop laboratory instrument utilizing the Coulter Principle to measure particle size distribution and concentration with exceptional accuracy and sensitivity. Equipped with a 70 µm aperture (other aperture sizes available), this particle size analyzer supports particle diameters ranging from 0.2 µm to 1600 µm and volume measurement from 0.004 µm³ to 2.14 x 10⁹ µm³. It is widely adopted in biopharmaceutical manufacturing, molecular diagnostics, synthetic biology research, and industrial quality control applications including cell counting, volume distribution analysis, and particle characterization in food, cosmetics, fuels, and chemical formulations.

Key technical features include:

The Multisizer 4e software interface enables intuitive instrument control and data analysis, making it popular among researchers in biotechnology, cell imaging, and bioprocessing quality control. The instrument supports small sample volumes (as little as 5 mL), making it essential for molecular cloning workflows and biopharmaceutical production pipelines that require rapid and reproducible particle size characterization. It is engineered for robust performance in critical clinical diagnostics and synthetic biology research environments.

The package includes:

The Multisizer 4e is factory tested and serviced, verified for functional calibration with 10 µm beads ensuring reliability in particle size and concentration quantification. The instrument benefits from options for remote setup, training, and warranty support, meeting the high standards required by academic, clinical, and industrial biotechnology laboratories.

This particle size analyzer remains a benchmark tool for particle size distribution measurement in biomedical engineering, biomanufacturing process control, and advanced pharmaceutical formulation development. Its aperture-based Coulter counting technique is critical for achieving reproducible and high-resolution particle analysis required in modern life sciences research and production environments.
