Polypropylene fibers are used in every aspect of carpet constmetion from face fiber to primary and secondary backings. Polypropylene s advantages over jute as carpet backing are dimensional stabiUty and minimal moisture absorption. Drawbacks include difficulty in dyeing and higher cost. Bulked-continuous-filament (BCF) carpet yams provide face fiber with improved crimp and elasticity. BCF carpet yams are especially important in contract carpets, characterized by low dense loops, where easy cleaning is an advantage. 

The vertical recessed plate automatic press is shown schematically in Figure 15. Unlike the conventional filter press with plates hanging down and linked in a horizontal direction, this filter press has the plates in a horizontal plane placed one upon another. This design offers semicontinuous operation, saving in floor space, and easy cleaning of the cloth, but it allows only the lower face of each chamber to be used for filtration. 

Chemical-Porcelain Pipe Made of dense, nonporous material and fired at 1230°C (2250°F), chemical-porcelain pipe, fittings, and valves are inert to all acids except hydrofluoric but are not usually recommended for alkalies. Surfaces, except when ground for gasketing, are usually glazed for easy cleaning. Working pressures of 0.3 to 0.7 MPa (50 to 100 Ibftin") are recommended for valves and piping. Temperatures of 200°C (400°F) or more can be used, but sudden thermal shocks must be avoided. 

In the food production and OTC (Over the Counter) Drug industries, like milk, soups, cough syrup, and juices, outside balanced seals are quite popular. Their design permits easy cleaning of the equipment without pump disassembly. These seals are prominent in the chemical processing industry because all metal components in the seal are located outside the fluid. This avoids problems of galvanic eorro.sion. 

The diameter and materials, specified for the tubes and fins, depend on system requirements. The fins are commonly made from aluminum or copper, but may be fabricated of stainless or carbon steel. Tubes are generally copper, but can be made from almost any material, and they range in size from 5/8- to 1-in. outer diameter. The design of the air-cooled exchanger is such, that individual coils can be removed independently for easy cleaning and maintenance. There are several common design configurations that are commercially available. Each is briefly described below. 

If a preheater coil is provided and positioned before the air filter, the heater should be either a plain tube or have wide spread fins for easy cleaning... 

Glass is one of the engineer s most useful and versatile materials. There are many types of glass to choose from to provide a wide range of physical, mechanical, electrical and optical properties for practically every type of environmental condition. The transparency of glass facilitates inspection of process operations and minimises the risk of failure due to unsuspected corrosion, while the hardness and smoothness contribute to easy cleaning. 

Although liquid Hg would never be used as a reference (model) surface in surface physics because its liquid state and high vapor pressure do not allow appropriate UHV conditions, this metal turns out to be a reference surface in electrochemistry for precisely the same reasons reproducibility of the surface state, easy cleaning of its surface, and the possibility of measuring the surface tension (surface thermodynamic conditions). In particular, the establishment of a UHV scale for potentials is at present based on data obtained for Hg. 

Easy cleaning and sanitizing make stainless steel popular in food or biological laboratories. Contact with strong mineral acids, however, will show that it is not quite stainless. An abrasive is required to remove such stains. While resistant, a steel top will temporarily bulge when exposed to heat, which sometimes can interfere with the alignment of equipment set-ups. 

CE has been used for the analysis of anionic surfactants [946,947] and can be considered as complementary to HPLC for the analysis of cationic surfactants with advantages of minimal solvent consumption, higher efficiency, easy cleaning and inexpensive replacement of columns and the ability of fast method development by changing the electrolyte composition. Also the separation of polystyrene sulfonates with polymeric additives by CE has been reported [948]. Moreover, CE has also been used for the analysis of polymeric water treatment additives, such as acrylic acid copolymer flocculants, phosphonates, low-MW acids and inorganic anions. The technique provides for analyst time-savings and has lower detection limits and improved quantification for determination of anionic polymers, compared to HPLC. 

Figure 4.11. a so liter bench fermenter that can be scaled for production of recombinant proteins. The bench-top scale configuration contains all the control valves and ports necessary to monitor and control cell cultivation while maintaining sterility of the culture. The stainless steal reaction vessel allows easy cleaning and permits heat and pressure sterilization in place by connecting the vessel to a steam supply.

Other precautions must be taken to prevent accidental or occasional increases in concentrations. Materials should be transported in safe containers, spilled material removed rapidly, and floor and wall materials selected to prevent contamination and allow easy cleaning. 

Cages, racks, and other equipment must be capable of regular, easy cleaning. The use of disinfectants and pesticides should be avoided, particularly where they may come in contact with the animals, since such biologically active compounds may affect the study results. More detailed information regarding animal husbandry management and procedures can be found in the scientific literature, animal welfare publications, and official documents of the GLP.

Podbielniak Phynal Stopcock Lubricant Designed for stopcocks, insoluble in hydrocarbons and most organic solvents, but soluble in water for easy clean up. Soluble in water. 

Improved hygiene. The totally enclosed system keeps the product safe from contamination and permits easy cleaning and disinfection. 

Even today, some items of equipment in the margarine production can be found not to be designed for easy cleaning and draining. Tanks with flat bottoms and inadequate drainage points can be found. Pipes are found with unnecessary bends, blank ends, and unsatisfactory valves. Such installations are very difficult to clean and could lead to the buildup of stagnant products.

Metal or reinforced fiberglass doors and doorframes are most desirable. Doorframes that terminate at the top of the cove base allow easy cleaning. Top locking of the inactive door is preferred for dual-panel doors because this eliminates the need for floor penetrations and cleaning concerns. The door closures should be readily cleanable.
