Derived from cell wall of gram neg bacteria

Used more broadly as any contamination by product from bact

Cannot be used for injections

Has to be with lower level of chemicals, micro and pyrogens than PW

Vaporizing and condensing for water purification

Uses resins to deionize water removing neg and pos ions and replacing them with OH and H ions

Water purification using activated carbon

Inexpensive method of filtration to remove particles larger than 10th

Synthetic polymer filters with specific spore size. Effectively removes bacteria

Filtration that can remove viruses and pyrogens

Filtration that removes solute with diameter of .001um

Removes materials down to molecular weight of 300

Three methods of water purification

4 ways to test water purification

Glass that is most common general purpose in the lab

Passing solutions that are heat sensitive through a small pore size filter for sterilizing

Sterilization by heating to generate steam and pressure

4 steps for storing proteins

Storing DNA and RNA

Storing intact cells
