The 121 degree temperature is maintained by the pressure itself, if the pressure were to drop bellow 15psi then the boiling point of the water would drop, and the temperature would fall. The boiling point of water is affected by pressure, the more pressure the higher the boiling point, hence a higher temperature.

How do you prepare a cotton plug for conical flask?
can pressure cooker be used in place of autoclave
Can culture media be sterilized in the oven?
No. Media sterilization requires 121C (250F) at 15psi for 15 minutes. It is generally done in an autoclave, but can be done in a pressure cooker. Tyndallization is another alternative, which is just boiling for 15 minutes three days in a row, and incubating at a warm temperature in between. It is not 100% effective. Instruments can be sterilized in an oven. Dry heat sterilization generally requires 160C (320F) for 2 hours or 170C (340F) for 1 hour.
What is autoclave paper?
paper that is used to wrap items that are placed in an autoclave for sterilization
What do you put in a autoclave?
An autoclave is used to sterilize medical instruments. They have a reservoir to hold the distilled water that is pumped or drained into the chamber.
Who invented the autoclave?
French physician Denis Papin
What is the tire pressure on the f1 cars?
about 15psi or 1.1bar.
Why is pressure required to kill endospores in an autoclave?
Pressure increases the boiling point of water, when it does boil the steam is now 'super-heated'. It is at a higher temperature than the boiling point of 100C (usually 121C and 15psi for an autoclave) this quickly transfers much greater amounts of heat energy to the object being autoclaved. The vast majority of microorganisms and even pathogenic bacterial spores cannot withstand this temperature and pressure for long, the lipids and proteins in their cell walls and membranes disintegrate and they are killed.
What is the correct tire pressure for Yamaha pw80?
15psi for the front and rear tire mate
What is 15 pounds pressure in autoclave?
Steam autoclave's work at 30 to 35 PSI, the previous answer of 15 PSI is for a pressure cooker. A pressure cooker cannot be used as an autoclave, the temperature is not high enough to cause sterilization. Anything less than 121C / 250F (30 PSI) is incapable of killing microorganisms. Also the pressure vesal of a pressure cooker cannot handle the added pressure needed to sterilize, IE: adding weight to the release valve will just cause the cooker to explode (so don't try it).
Why high pressure needed in autoclave?
To sterilise effectively the water in the autoclave needs to reach a temperature of 120°C. Since water at atmospheric pressure boils at 100°C, a higher pressure is needed to reach that temperature.
What is the low side pressure of a freezer using R 404A refrigerant?
if room tem is 70f 15psi
What is the low side pressure of a freezer using R-404A refrigerant?
if room tem is 70f 15psi
How do you determine the pressure of the nitrogen and oxygen?
You need some sort of an instrument. Most of us just use a pressure gauge, although you could do it empirically--you could throw the end of the hose in water, and if bubbles came out you would know the gas pressure is at least as high as the water pressure--which is 15psi since the 15psi atmosphere is pressing down on the water.
How do you test the efficiency of an autoclave in microbiology?
An Autoclave is a piece of equipment used for sterilization purposes and requires quarterly calibration. There are three types of calibrations to be done - timer, temperature and pressure. To calibrate the timer, post an appropriate correction factor directly on the autoclave. Post a correction factor on the autoclave control panel if the temperatures were different, and for pressure post a correction factor on the autoclave if it is not true.
What is an autoclave reactor?
a reactor is generally termed as an autoclave reactor,when it is a high pressure batch reactor.mostly this kind of reactors are used for sterilization the reactants..
What is a sterilizing machine called that steams and heats under pressure?
Autoclave
What is a pressure cooker-like apparatus used to sterilize instruments called?
Autoclave.
