Glass special containers

Freeing a solution from extremely small particles [e.g. for optical rotatory dispersion (ORD) or circular dichroism (CD) measurements] requires filters with very small pore size. Commercially available (Millipore, Gelman, Nucleopore) filters other than cellulose or glass include nylon, Teflon, and polyvinyl chloride, and the pore diameter may be as small as 0.01 micron (see Table 6). Special containers are used to hold the filters, through which the solution is pressed by applying pressure, e.g. from a syringe. Some of these filters can be used to clear strong sulfuric acid solutions. 

Predictably with an NP-rich product like wine, consumption is accompanied by ritual. Wines are served at official dinners, at weddings, to celebrate births and to show displays of triumph after car racing. Special drinking vessels (wine glasses), special storage containers (wine bottles), special storage racks and wine cellars, all point to wine having a special value in European culture. 

Animal anesthesia can be achieved with isoflurane without the use of specialized anesthesia equipment. Place animal(s) in a bell jar or screw top glass jar containing a cotton wool pad soaked with 1-2 ml of isoflurane until areflexic. After removal of the animal(s) from the jar, place the nose in a 50 ml Eppendorf tube with an isoflurane soaked cotton pad at the bottom. This method requires frequent evaluation of the depth of anesthesia. 

Pasteur pipettes are very useful for transferring small quantities of liquid, adding reagents dropwise, and carrying out crystallizations. Surprisingly, the acetone used to wash out a dirty Pasteur pipette usually costs more than the pipette itself. Discard used Pasteur pipettes in the special container for waste glass. 

Dispose of all sharps (broken glass and other contaminated sharp objects) and other contaminated materials (biological and chemical) in special containers as directed by your instructor.
