Items starting with C

Canned

Canned Centrifugal Pumps. These centrifugal pumps are used when materials are hazardous and the risk of a leak unacceptable. They are enclosed in a can or container that has no seals that can fail. Canned pumps are of two types. One type has a separate external motor which drives the pump. Magnetic drives act as a link between the shaft and impeller. The other type has the motor and pump in an enclosure with only the electrical connections for the motor passing through the can. Because there are no moving parts in the electrical connection, there is no possibility of a leak.

Capacitive Level Transmitter

Capacitive Level Transmitters. These devices, also called RF level transmitters, use a radio frequency technique based on differing dielectric constants. The impedance detected by the radio frequency changes whenever material approaches the sensing region. These transmitters are used with wide variety of solids, aqueous and organic liquids, and slurries. They contain no moving parts, are rugged, simple to use, easy to clean, and can be designed for high temperature and high pressure applications. The device generates an electrical signal that can be used to control a readout or other device. These transmitters can provide both point level detection and continuous monitoring.

Carbon Adsorbtion Scrubbers

Carbon Adsorption Environmental Scrubbers. These scrubbers perform in the same manner as those described above in General Environmental Scrubbers, except that activated carbon is the material used to remove gases and odors from the air stream. Carbon scrubbers are used where the concentration of volatiles are low, and the air volumes are relatively large. The gases are removed by adsorption, meaning the gas is gathered in a condensed layer on the surface of the carbon. The used carbon is usually contained or buried to prevent environmental contamination.

Carbon Steel

Carbon Steel Piping: This piping is an alloy of iron and carbon. Carbon steel exhibits high yield stress, high tensile strength, elasticity, ductility, and lack of brittleness which enable it to operate at high pressures. Carbon steel pipes have greater carrying capacity for a given pressure over pipes made with other materials with the same outer diameter. Carbon steel pipes are supplied in longer lengths than pipes made with other materials, requiring fewer assembly joints. Corrosion is a major disadvantage in carbon steel pipes.

Carbon/Graphite

Carbon/Graphite Heat Exchangers. Several types of carbon/graphite are manufactured that are identical in operation to their metal counterparts. These heat exchangers can be used with many acids and with combustion gases, and they are resistant to most organic and inorganic media. The graphite material offers excellent corrosion protection, low pressure drops, high efficiency, large heat exchange areas, and resistance to stress and pressure surges.

Cartridge

Cartridge Filters. A sediment filter. They can be surface filters that block particles on the filter's surface, or depth-type filters that capture particles through the total thickness of the medium. Cartridge filters are normally designed to be disposable and must be replaced when clogged.

  • Code: 18-10-02

Catalog

Equipment Catalog. A publication with a systematically arranged listing of products available from the company issuing the publication. Usually focused upon a limited product line such as laboratory equipment, industrial equipment, safety products, etc.

  • SPEC #: 18809
  • Code: 18-00-09

Centrifuges

Centrifuge: A motor-driven device that rotates objects around a fixed axis, applying force perpendicular to the axis. Centripetal acceleration separates substances of greater and lesser density. There are many different kinds of centrifuges, some quite specialized. Centrifugation protocols typically specify acceleration to be applied to the sample, rather than specifying a rotational speed. Acceleration is often measured as multiples of g, acceleration due to gravity at the Earth's surface.

  • Code: 18-16-22

Check

Manual Check Valve: A valve that allows liquid or gas to flow through it in only one direction. Check valves have only two ports: one for input and one for output. Check valves work automatically and are not controlled by a person or any external control.

  • SPEC #: 17870

Chiller

Chiller: A machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. They come in several different mechanical arrangements: reciprocating, rotary-screw, and centrifugal, and with unlimited combinations of features, capacities, and efficiencies.

  • SPEC #: 15620
  • Code: 18-17-02

Chromatography Systems

Biopharmaceutical Chromatography Systems. Chromatography is the collective term for a family of laboratory techniques for the separation of mixtures. Chromatography may be preparative or analytical. Preparative chromatography separates components of a mixture for further use. Analytical chromatography measures the relative proportions of components in a mixture. Ion chromatography is a process that allows the separation of ions and polar molecules based on the charge properties of the molecules. It can be used for almost any kind of charged molecule including large proteins, small nucleotides and amino acids.

CIP Skids

CIP Skids. CIP (Cleaning In Place) skids are commonly used to mount and support equipment in chemical and pharmaceutical plants where process optimization depends upon efficient, effective cleaning. Most CIP skids are custom designed to be compatible with the equipment mounted on them. It involves integrating features such as spray systems, tank cleaners, nozzles, and seals into the skids, in order to automate the cleaning process.

Clamp-On Dimple Jacket

Clamp-On Dimple Jacket Heat Exchanger. These jackets consist of hemispherical dimples pressed into a thin plate, which is then wrapped around and clamped onto the vessel. They are frequently used to heat or to cool process vessels in the chemical process industries. They have better heat-transfer characteristics than conventional jackets due to the turbulence generated by the dimples. They can be fitted to both cylindrical and dished portions of a process vessel. Dimple jackets typically give high pressure ratings, have a low to moderate pressure drop, and are moderate in cost.

  • Code: 18-07-15

Clamp-on Plate

Clamp-on Plate Heat Exchangers. These heat exchangers offer a convenient way to add heating or cooling to the exterior of tanks or vessels. The plates are fitted to the tank exterior to provide moderate heating or cooling. Because they do not directly contact the substance within the vessel or tank, they cannot contaminate the product. The clamp on plates should be installed with a heat transfer mastic to increase their overall performance

Clean Steam

Utilities, Clean Steam: An in-house generation/storage and distribution system found in laboratories and industrial facilities, ensuring the availability and delivery of compressed air upon demand, to specified locations and activities.
