Triton X-100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group.
A surfactant (surface active agent), such as hand-dishwashing liquid detergent, can be added to the water to significantly lower the surface tension of the water. This liquid solution will flow more easily and more rapidly in the tube than plain water, so operation of the device will be more precise, repeatable, and responsive – particularly ...
The higher water use by jacketed autoclaves resulted in an estimated water cost of $764 per jacketed autoclave per year, compared to $23 for non-jacketed autoclaves. With over 100 steam-jacketed autoclaves on campus, the author calculated that using jacketed autoclaves for research tasks translated into an additional $74,000 in annual excess ...
This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave, sometimes called a converter or steam sterilizer. The object or liquid is placed in the autoclave chamber, which is then sealed and heated using pressurized steam to a temperature set point for a defined period of time.
A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [2]: 13 [3] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not protect the work materials from contamination by the surrounding environment.
Moist heat sterilization processes sterilize using hot air that is heavily laden with water vapor, which plays the most important role in the sterilization. [ 1 ] [ 2 ] Boiling a sample for 30 minutes or more will kill virtually all vegetative cells present, but will not kill spores , which can germinate shortly thereafter and resume growth.
A mechanical convection oven contains a blower that actively forces heated air throughout all areas of the chamber. The flow created by the blower ensures uniform temperatures and the equal transfer of heat throughout the load. For this reason, the mechanical convection oven is the more efficient of the two processes.
Out of autoclave (OOA) is a process that achieves the same quality as an autoclave but through a different process. [1] OOA curing achieves the desired fiber content and elimination of voids by placing the layup within a closed mold and applying vacuum, pressure, and heat by means other than an autoclave.
