Carrier plastic

Strategies including charging customers for plastic carrier bags, and taxing their use. This latter approach has been very successful in Ireland, where there has been a significant growth in pubhc awareness of their impact on the environment, and a fall in their use by 90%. 

Biological indicators (Bis) for use in thermal, chemical or radiation sterilization processes consist of standardized bacterial spore preparations which are usually in the form either of suspensions in water or culture medium or of spores dried on paper, aluminium or plastic carriers. As with chentical indicators, they are usually placed in dummy packs located at strategic sites in the sterilizer. Alternatively, for gaseous sterihzation these may also be placed within a tubular hehx (Line-Pickerill) device. After the sterilization process, the aqueous suspensions or spores on carriers are aseptically transferred to an appropriate nutrient medium which is then incubated and periodically examined for signs of growth. Spores of Bacillus stearothermophilus in sealed ampoules of cultrrre medium are used for steam sterilization morritoring, and these may be incubated directly at 55°C this eliminates the need for an aseptic transfer. 

This plastic carrier bag is made from a substance that is made from the chemical elements carbon and hydrogen only. When the carrier bag is burned it produces carbon dioxide and water. These substances are natural and will not harm the environment. 

Two other filtration modules, which both formed part of automated radioimmunoassay systems, have been developed. - One of these, was based on conventional continuous flow techniques. At the filtration stage, a continuously moving strip of glass fiber filter paper was strengthened and wetted, the reaction mixture was filtered, and the precipitate was washed by two streams of buffer. The strip was dried and overlaid with cellulose adhesive tape before being counted as it passed between two end-window radioactivity detectors and wound onto a take-up spool. In the second system, glass fiber filter disks are mounted at intervals over perforated segments of a flexible plastic carrier tape. The contents of five... 

The concentration of the reaction product that has formed as a dye is quantified more closely by measuring the reflectance. However, the light is not only reflected by the surface of the test area, but it also penetrates into the field (Fig. 48). In the matrix the light is influenced by both the liquid and solid components. Whereas the solid components (cellulose fibres) scatter the light, the liquid components, which contain the reaction products, absorb it. These events take place before and after the light is reflected from the place of intersection of the matrix and the plastic carrier, i.e. as the light passes through the test area. 

Immobilization of Pseudomonas aeruginosa. Seeking an improvement on some earlier fixed-bed biological reactors, the primary criterion in selecting a plastic carrier was the firm attachment of the microbe to the plastic. This can be achieved if the microbe is either using the plastic as a carbon source and thereby burrows itself into the plastic, or if the plastic surface is treated, e.g., by plasma treatment, to facilitate chemical bonding. 

Plastabs can be efficiently used in a similar way to cor-tabs in the preservation of machines and equipment. They are made in the form of thin plates cut from sheets formed from a mixture of a powder inhibitor and polymer solution. VCI-based plastabs are believed to provide close to ideal protection for ferrous and nonferrous metals against corrosion, particularly in gaps and narrow clearances. One of the well-known manufacturers of such plastic carriers is the Northern Instruments Corp. (USA).

A9.3 4 Cooling of the Shuttle. The cooling required by the loaded carrier is a function of the total mass and the desired oiaximum temperature. Since it may become necessary to irradiate samples that have a low decomposition temperature, such as hydrocarbons, the cooling system should be capable of limiting the maximum sample temperature to approximately 300°F. In addition, the use of a plastic carrier would limit the temperature to a similar maximum. It is estimated that the upper limit on the mass of a loaded shuttle will be, 25 g. To cool this shuttle and the shock absorber with air, a flow of 0.04 Ib/sec is required. This value is based on a heat transfer area of 9.-6 sq in. with a 3-in.-long carrier.
