Founded in 1962, Micromeritics is a leading supplier of materials characterization analytical laboratory instrumentation and services.
Material characterization analytical laboratory instruments
The company manufactures a broad line of automated laboratory instruments that measure physical characteristics of powders and solids for fundamental research, product development, quality assurance, control, production, and process control applications.
Measurements obtained include particle size, particle shape, surface area, pore volume, pore and size distribution and material density.
Particulate Systems, a Micromeritics brand, provides instruments that measure nano particle size, zeta potential, particle shape, high-pressure adsorption isotherms, dynamic vapor sorption, activity and selectivity of catalysts, surface energy, segregation testing, powder strength, and determination of low levels of iron content in a variety of materials.
Material characterization analytical services
Micromeritics operates Micromeritics Analytical Services (MAS) and Micromeritics Pharmaceutical Services (MPS), which both provide contract sample analyses and consulting services.
Materials characterization services include: particle size, particle shape, particle count, nano particle size, surface area, micropore analysis, pore volume distribution, total pore volume, mercury injection capillary pressure, density, surface energy, dynamic water vapor sorption, TGA, DSC, magnetic content, zeta potential, microscopy, method development, method validation, and consulting services.
Micromeritics Pharmaceutical Services (MPS) enables Micromeritics to expand its analytical service capabilities and meet the growing demand for contract services from the pharmaceutical industry.
Additional services include API characterization, excipient screening, powder flow properties, batch variability, identification of critical quality attributes, and quality by design (QbD) / process analytical technology (PAT) implementation.
Surface area and porosity analyzers
Micromeritics offers a variety of gas adsorption analyzers to fulfill almost any surface area and porosity need.
The 3Flex™ is a fully automated, three-station instrument capable of high-throughput surface area, mesopore, and micropore analyses.
Each analysis station is upgradeable from mesopore to micropore with its own set of pressure transducers.
The Tristar® II Series are automated, three-station, surface area and porosity analyzers capable of increasing the speed and efficiency of quality control analyses, with the accuracy, resolution, and data reduction to meet most research requirements.
It features a krypton option, allowing measurements in a very low surface area range. The Gemini® VII series surface area analyzers offer fast, accurate, and reliable surface area and porosity results.
Their low cost, small footprint, speed, accuracy, simplicity of use, reliability, and ruggedness make the Gemini series an ideal tool for teaching, research, and quality control environments. Low to high surface area measurements can be performed without requiring the use of krypton.
Porosimeters
The AutoPore® V series porosimeters use mercury intrusion and extrusion to determine pore size distribution, total pore volume, percent porosity, density, compaction, compression, and fluid transport properties.
Enhanced data reduction package includes tortuosity, permeability, compressibility, pore-throat ratio, fractal dimension and Mayer-Stowe particle size distribution.
Particle size analyzers
The Saturn DigiSizer® II laser particle size analyzer utilizes advanced optics, CCD technology, and more than three million detector elements to deliver a high-resolution measurement of articulations in the scattering pattern.
This allows a high degree of size discrimination or resolution. It automatically determines organic and inorganic particle sizes ranging from 40 nanometers (nm) to 2.5mm.
NanoPlus utilizes photon correlation spectroscopy and electrophoretic light scattering techniques to determine nano particle size and zeta potential.
Compact and easy-to-use with an extended analysis range, intuitive software, and multiple sample cells to fit the user’s application, the instrument can measure particle size in the range of 0.1nm to 12.30μm with sample suspension concentrations from 0.00001% to 40% and zeta potential of sample suspensions in the -500 mV to 500 mV range with concentrations from 0.001% to 40%.
Pycnometers
The AccuPyc® II 1340 is a fully automatic gas displacement pycnometer that produces high-speed, high-precision volume measurements and density determinations of powders, solids, and slurries with volumes of 0.01 to 350 cm³.
Gas pycnometry is recognized as one of the most reliable techniques for obtaining skeletal volume and density.
The GeoPyc® 1360 utilizes a quasi-fluid displacement medium composed of non-hazardous microspheres with a high degree of flowability that do not wet the sample or fill its pores.
It determines envelope volume and density of monolithic samples, as well as the bulk volume and density of powdered materials. GeoPyc pycnometer automatically calculates the total pore volume when the skeletal volume is known. It is non-destructive for most samples.
Particle characterization instruments
Micromeritics has provided material characterization instruments and applications support to most of the world’s top industrial companies and academic institutions whose applications include: pharmaceuticals, clays, ceramics, pigments, plastics, catalysts and catalyst support systems, paper coatings, geological cores, and metal powders.
The company operates direct offices located in the US, England, Germany, Belgium, France, Italy, China, and Japan.
In addition, a specially trained local representative worldwide network sell and service Micromeritics’ material characterization instruments.
