| Property Analyzed: | |||
| Your choices are... | |||
| Pore Distribution | Pore distribution is the frequency with which pores occur in a sample. | ||
| Pore Size / Densometry | Instruments for pore size measurement. Densometers are used for measuring porosity, air-permeability or air resistance of sheet-like or bulk materials such as paper, woven cloth, porous plastics, nonwovens textiles, filtration media and membranes. Densometers measure by determining the time required to drive or flow a fixed, known volume of air through a sample. Some densometers or densometry instruments also provide smoothness and softness indications through permeation measurements. Nuclear densometers are used to measure porosity, density and moisture content in soil, asphalt, concrete and pavement field applications. | ||
| Pore Volume / Porosimetry | Porosimeters measure the pore volume and distribution in a bulk material. They use either liquid intrusion into pores or liquid extrusion from pores to measure pore volume. Porometers or bubble point testers determine the point at which pressure can overcome capillary action in a porous material. | ||
| Surface Area - Specific | The specific surface area of a powder is determined by physical adsorption of a gas on the surface of the solid, and by measuring the amount of adsorbate gas corresponding to a monomolecular layer on the surface. | ||
| Surface Area - Total | Surface area can be determined by measuring the amount of material required to form a single layer - a monolayer - on the surface. If the area per molecule or ion adsorbed is known, then the total surface area from such a measurement can be calculated. | ||
| Other | Other unlisted, specialized, or proprietary configurations. | ||

|
|
| ||
| Specific Surface Area Range | Specific surface area range is given as the surface area in square meters per gram of a sample. Specific surface area is proportional to specific pore volume, and inversely related to the pore diameter. It is measured by nitrogen adsorption. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Total Surface Area Range | Total surface area range is given as the surface area of square meters. It is a measure of the entire surface area of the particle. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Pore Diameter Range | Pore diameter range is given as a distance, usually in nanometers or angstroms. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

Test Media / Material
Back to Top
|
|
| ||
| Your choices are... | |||
| Adhesives / Coatings | Devices test substances that coat, fasten, bond, or seal materials. Adhesives that bond and seal are called adhesive sealants. Coatings are thin layers of protective or decorative compounds that are bonded to the surface of a substrate by a variety of methods. Wetting and surface energy are key properties in the processing and function of coatings, adhesives, and sealants. | ||
| Asphalt / Pavement | Devices are designed to evaluate the properties of asphalt or other types of pavement materials. | ||
| Building & Construction Materials | Devices are designed to evaluate building and construction materials such as metal, plastic, rubber, asphalt, concrete, cement, mortar, adhesives, sealants, rock or aggregate, soil, wood , textiles, and foam. | ||
| Ceramics / Glass | Ceramics consist of oxides, carbides, nitrides, carbon, and other non-metals with high melting points. Ceramics are suitable for applications requiring wear resistance, refractoriness, low electrical resistivity, or other specialized characteristics. | ||
| Chemicals | Devices test liquid, gas, powders, or solid substances that have a distinct molecular composition and are produced by a chemical process. | ||
| Concrete / Cement | Devices are designed to evaluate the properties or workability of concrete, mortar, or cement products. Concrete is a mixture of Portland cement, water, and aggregate. Mortar contains these same ingredients along with hydrated lime and sand to facilitate workability and decrease working time. | ||
| Food / Drugs | Devices are designed to test food, drugs, drug additives, food additives, beverages, pharmaceutical materials, active pharmaceutical ingredients (APIs), or food ingredients for properties such as contamination, flow, texture, stability, melting point, freezing point, foamability, dissolution, or water absorption. | ||
| Fuel | Devices are designed to test traditional fuels like petroleum and fossil fuels, renewables like biomass and biofuels, and emerging technologies including hydrogen and nuclear materials, for properties including energy density, blend composition, and octane / cetane level. | ||
| Geological (Rock, Strata, etc.) | Devices are designed to test or perform geophysical analysis on geological materials such as rock, stone, soil, strata, etc. Such test equipment is used to provide tests in the field, core or extract specimens (sampling), or provide laboratory analysis on samples (cores, specimens) taken from the field. | ||
| Metals | Devices are designed to test metals or alloys with two or more metallic elements. As a category, metals include electropositive elements that are generally good conductors of heat and electricity, and that can be melted or fused, hammered into thin sheets, or drawn into wires. | ||
| Oils / Lubricants | Devices are designed to test greases, oils, lubrication oils, solid lubricants, distillates, or other petroleum products. | ||
| Packaging Materials | Devices are designed to test packaging materials, which include films, tapes, bags, and containers of plastic, elastomer, glass, or foam compositions. | ||
| Polymers (Plastics, Elastomers) | Devices are designed to test polymers, plastics, and elastomers. Polymers are organic, synthetic, or processed materials typically consist of thermoplastic or thermosetting resins. Plastic testers or test equipment tests any of various organic compounds produced by polymerization. These materials can be molded, cast, or extruded into various shapes and films. Rubbers and elastomers are polymers that exhibit very high elasticity and resilience compared to plastic polymeric materials. | ||
| Porous Materials (Filters, Foam, etc.) | Devices test foam, filters, filtration media, and other porous materials. | ||
| Powders / Granular Materials | Powders and granular materials are finely divided forms of metals, ceramics, polymers, composites, minerals, or other raw materials. | ||
| Pulp / Paper | Paper is made of cellulose pulp and derived mainly from wood. | ||
| Rock / Aggregate | Devices can be used to evaluate rock, stone, crushed ore, or aggregate in the field, or to test a sample removed from the field. Minerals and ores are raw materials that are crushed, milled, extracted, refined and/or processed to produce finished products such as glass, fillers, reinforcements, cement, metals and ceramics. | ||
| Soil | Soil, the top layer of the earth's surface, consists of rock and mineral particles mixed with organic matter. | ||
