Gloves components

In addition to the soHd form of natural mbber it is available as a soHd suspended in water, known as latex. Synthetic mbbers are also available in latex form. Latex has become an important commodity used in the manufacture of dipped goods for health and disease protection. The principal uses of natural mbber are as follows tires and retreading, 70% latex (gloves, balloons), 12% mechanical goods, 9% load-bearing components, 4% and other, 5%. 

A reaction kettle equipped with mechanical stirrer was placed in a glove box filled with nitrogen and heated to 120°C for 1 hour to remove moisture. The reactor was then charged with glycolide (200 g), y-caprolactone (200 g), 0.27 ml dodecanol, 700 ml of xylene, and 1.12 ml of stannous octoate and where glycolide component was added over four portions in 2-hour intervals. The mixture was then stirred at 120°C for 90 hours and the product isolated after dissolving in chloroform and precipitated in methanol. 2... 

In an asymmetric synthesis the effect of a chiral reference system is due to the fact that it interacts with a chiral molecular system and the mirror image of the latter in a different manner, just like a right hand interacts differently with right and left-handed gloves. These differences in interaction are chemically observable as stereoselectivity. Complex schemes of chemical reactions may contain asymmetric syntheses as partial reactions which can be conceptually separated from the other parts of the scheme. In some of these cases the whole reaction scheme may even not qualify as an asymmetric synthesis, because it leads to dissipation of chirality due to the presence of chirality dissipating components whose contribution to the overall result is predominating... 

Alkaline, alkaline earth metals and aluminum are naturally covered with anodic films. The removal of these native films, even in the best glove box atmosphere, exposes the fresh metal to reactive atmospheric contaminants at a high enough concentration and quickly cover the metal with new surface films. As discussed above, even the glove box atmosphere of an inert gas containing atmospheric components at the ppm level should be considered as being quite reactive to active metals such as lithium. Therefore, anyone intending to study the intrinsic behavior of active metal electrodes in solution must prepare a fresh electrode surface in solution. 

Glove box technique — A glove box is a device that enables to work with materials which are sensitive to atmospheric components, under inert atmosphere (Ar, N2, or dry air depending on need and reactivity of materials). 

Ordinarily, present within the preparation area are localized areas of ISO 5 unidirectional airflow (Class 100) utilized to protect washed components prior to sterilization and/or depyrogenation. These areas are not aseptic and should not be subjected to the more rigorous microbial expectations of aseptic processing. They are designed to reduce/eliminate the potential for particle contamination of unwrapped washed materials. Operators accessing these protective zones wear gloves at all times when handling materials.
