Air scrubbers, wet scrubbers, and gas scrubbers are air pollution control devices that use a high-energy liquid spray to remove aerosol and gaseous pollutants from an air stream. The gases are removed either by absorption or chemical reaction.

Hydraulic Filters

(435 companies)
Hydraulic filters are used for handling petroleum-based oils, emulsions, synthetic hydraulic fluids and lubrication oils.

Refractometers

(163 companies)
Refractometers measure the critical angle of refraction through a sample. The critical angle of refraction will change with concentration.
Spill containment systems are used to capture and contain unintentional spills of liquid media. They are also called secondary containment systems.

MSDS Software

(20 companies)
MSDS software is used to create, manage and distribute material safety data sheets (MSDS) for chemical products.
Reagents and laboratory chemicals include substances of sufficient purity for use in chemical analysis, chemical reactions or physical testing. Purity standards for reagents and laboratory chemicals are set by organizations such as ASTM International or the American Chemical Society.

Fuel Cells

(123 companies)
Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum. Reformers are often used in conjunction with fuel cells.

Balls and Sphere Shapes

(211 companies)
Balls and sphere shapes are used in products that require a spherical component. Examples include bearings, ball screws, valves, flow meters, and gages. Balls and sphere shapes are made from materials such as glass, metals, plastics, and ceramics.
Primary refrigerants use a thermodynamic or adiabatic process (evaporation-condensation cycles) to remove heat and cool a region. Secondary refrigerants such as antifreeze liquids provide cooling solely through heat transfer.
This method covers determination of the specific gravity of soils by means of a pycnometer. When the soil is composed of particles larger than the 4.75-mm (No. 4) sieve, the method outlined in T 85 shall be followed. ASTM C1039 - These test methods cover...

Burners

(290 companies)
Burners are heating devices that use air supplied specifically for the combustion of a fuel gas.

Electrolytes

(34 companies)
Electrolytes are electrically-conductive materials that are used in batteries, fuel cells, capacitors, and biochemical systems. They typically exist as ionic solutions, or as molten salts or solids.
Inorganic chemicals, inorganic salts and inorganic compounds are substances of mineral origin that do not contain carbon in their molecular structure.
Chemical manufacturing and synthesis services produce organic chemicals and inorganic chemicals on a contract, toll, customized, or research and development basis.

Columns

(133 companies)
Columns are vertical structural elements that use compression to transmit the weight of a structure above to other structural elements below.
