Chemical Glassware

If you work on laboratory you will familiar with glassware apparatus that usually use as many tools in laboratory. Most of glassware that use for chemicals fluid have a size with volume indicator, even not all this glass apparatus will use for measure liquid volume. The different of this measuring ruler is the thoroughness. Glass use for volume measure will have more accuracy compare with glass that is not use to measure the volume.


 The glass with smaller inlet section called as Erlenmeyer, this glass is not purposes to measure the liquid volume even though there is a measurement indicator on the glass wall. The chemical glass with the same inlet section with the bottom called as Chemical Glass, this glass is not use for volume measurement but just keep or storage the chemical inside with the volume prediction. The highest glass on the picture above called as measuring cylinder, this glass is used for volume measurement. Measuring cylinder is just use to measure the volume of fluid or chemicals but not to keep the chemical after measure the volume.

Measuring cylinder have several volume type, the smallest have 1 ml and other size are 5 ml, 10 ml, 25 ml, 50 ml, 100 ml and more bigger.More bigger the measuring cylinder will have more roughly measure size its mean more not accurate.

Sodium Sulfite and Sodium Hydrosulfite

Sodium Sulfite Sodium sulfite is a compound that is very easily oxidized. For this reason, it is employed in many cases where a gentle reducing agent is desired, e.g. to bleach wool and silk, as an antichlor after the bleaching of yarns, textile and paper, as a preservative for foodstuffs, and to prevent raw sugar solution from colouring upon evaporation. It is very widely used in the preparation of photographic developer to prevent from oxidation from hydroquinone and other agents. It has a small application in the field of medicine as an antiseptic and as an antizymotic for internal use. About 60% of the total merchant market is in the paper Industries. While merchant capacity is about 145,000 t/year, the paper mills have twice capacity to captive use. The demand for boiler feed water treatment is about 15%. It is use to remove oxygen from water and thus help to prevent corrosion and scale formation. These were four major production in 1891, one of which provided 50% percent of the...

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo...

Sulfur

Sulfur or sulphur is a naturally occurring, yellow, water insoluble solid element. Its chemical symbol is S , its atomic number is 16 and its atomic weight is 32.064 sulfur is nonmetal and a member of the oxygen family of elements, which constitutes Group VIA of the periodic table. The discovery of sulfur predates recorded history, and the element has been used since ancient times. The early medical books of Dioscorides of Greece and Pliny the Elder mention sulfur, and fumes from burning sulfur were used in religious ceremonies and for fumigation. Alchemists recognized sulfur as a mineral substance that can be melted and burned. It was first classified as an element by Antonie Lavoisier in 1777. Sulfur Occurrence On earth, sulfur is widely distributed in its elemental state as a secondary mineral or as a volcanic deposit, as well as in combination with a number of metals. Large sedimentary deposits of the almost pure element, mainly of Tertiary age, are found in the coastal r...
