How To Work with Glass Tubing in the Lab

Glass tubing is used to connect other pieces of lab equipment. It can be cut, bent and stretched for a variety of uses. Here is how to work glass tubing safely for a chemistry lab or other scientific laboratory. Types of Glass Tubing There are two main types of glass that are commonly found in glass tubing using in labs: flint glass and borosilicate glass. Flint glass gets its name from the flint nodules found in English chalk deposits that were a source of high purity silica, which was used to produce a potash lead glass. Originally, flint glass was a leaded glass, containing anywhere from 4–60% lead oxide. Modern flint glass tends to contain a much lower percentage of lead. This is the most common type of glass worked in labs because it softens at low temperatures, such as those produced by an alcohol lamp or burner flame. It is easy to manipulate and inexpensive. Borosilicate glass is a high-temperature glass made from a mixture of silica and boron oxide. Pyrex is a well-known example of borosilicate glass. This type of glass cant be worked with an alcohol flame; a gas flame or other hot flame is needed. Borosilicate glass costs more and typically isnt worth the extra effort for a home chemistry lab, but it is common in school and commercial labs because of its chemical inertness and resistance to thermal shock. Borosilicate glass has a very low coefficient of thermal expansion. Selecting Glass To Use There are other considerations besides the chemical composition of the glass tubing. You can buy tubing in various length, wall thickness, inside diameter and outside diameter. Usually, the outside diameter is the critical factor because it determines whether or not the glass tubing will fit in a stopper or other connector for your setup. The most common outside diameter (OD) is 5 mm, but its a good idea to check your stoppers before buying, cutting or bending glass.

Essays on Application report 1 Coursework Finance and accounting al affiliation Introduction In order to analyses two companies’ performance, thereare various techniques used. One such technique is vertical analysis. It results into a common size financial statement making it easy to compare its performance to that of other firms irrespective of its size. Another technique is the use of accounting ratio analysis. For compressive analysis of General Motors Company (GM) and Ford Motor Co. (F) I’m going to use accounting ratio analysis. Financial statements Total stockholders’ equity for General Motors Company (GM) and Ford Motor Co. (F) fluctuate annually in the same trend. The similarity on trend is an indication of an industrial factor that is causing the fluctuation, such factors or beyond manager’s control. Net income of Ford Motor Co. (F) indicates a fluctuating trend while net income of General Motors Company (GM) is declining continually. All the above factors can be analyzed using ratio analysis as followers; Graham, J. R., Smart, S. B., Megginson, W. L. (2012).   Ratio analysis Ford Motor Co.

This has affected both firms ability to pay for their debt in 2013. These ratios indicate that Ford Motor Co. (F) is more efficient than General Gilbertson, C. B., Lehman, M. W. (2013).   Motors Company (GM) in terms of ability to pay debt. Overall performance of management is assessed by market value of the firm. Brigham, E. F., Ehrhardt, M. C. (2010).   Price earnings ratio of Ford motor co. is better than that of general motors. This is an indicator that ford motor co is performing better. Conclusion Preparation of this report has improved my understanding in units covered like accounting ratios, preparation and of financial statement analysis. References Brigham, E. F., Ehrhardt, M.
