ChEmICaLs UsEd In LaBoRaToRaToRy

Laboratory chemicals, solids, liquids or gases have discrete molecular composition and are used extensively in clinical and research laboratories. As temperature changes, these solid or liquids or gases may change into other states or phases. Chemicals utilized in laboratories have numerous uses. For instance, in chromatography, electrophoresis or life sciences research as bio reagents, biological buffers, inhibitors, stains and tracking dyes. Chemical solutions are used as indicators, reagents for testing and analysis for preparation of volumetric solutions. Similarly, amino acids and derivatives, inorganic compounds, solvents, and biopharmaceutical agents have countless applications in laboratories.

Solvents

Solvents, clear and colourless are of 2 types which are organic and inorganic. In general, solvents have low boiling point and evaporate quickly leaving the soluble matters behind. Solvents are used in range of applications such as dry cleaning, nail polish removers, glue solvents, spot removers, paint thinners, perfumes, detergents, chemical synthesis, and research chemistry. Solvents require careful handling as they pose serious dangers to human lives. These chemicals should be stored in tightly closed containers in a well-ventilated area. They should never be flushed down the drain and used near the open flames.



Reagents
Are the substances or indicators used for detecting, analyzing and identifying chemical processes? Fundamental types of reagents used in chemical reaction are acetal, acetyl, benzyl, methyl agents, methyl esters and other more. More accurately, these chemicals are added in order to trigger chemical change. The reagents industry is worth US$382 million, which has the enormous potential to reach US $ 400 million by the end of 2011.


HPLC Solvents
HPCL: high performance liquid chromatography -
Are solvents that are used in many application areas including process control, forensic analysis, environmental monitoring, clinical testing and quality control. These solvents are mainly used for separating, identifying and measuring components presented in a mixture of chemical substances. The widely used HPLC solvents are formic acid, pyridine, trifluroacetic acid, acetonitrile, dimethylsulfoxide, heptafluorobutyric acid and dimethylformamide.
