Many graduate students in laboratories have to clean their own experimental equipment and perform high-pressure sterilization. Here are some precautions for pressure cookers, hoping to be useful to everyone

Warning:

1、 This high-pressure steam sterilizer cannot be used to disinfect any destructive materials or substances containing alkali metal components Disinfection of these items will cause explosions or corrosion of the inner container and internal pipes, as well as damage to the gaskets

Dangerous Goods List:

1. Explosive substance

Ethylene glycol dinitrate (nitroglycerin), nitroglycerin, nitrocellulose (nitrocellulose filter), and all esters containing nitrate ions

*Yellow *, picric acid and all flammable and explosive nitro, peracetic acid, methyl, ethyl, methanol, hydrogen peroxide, peroxides, benzoyl, benzoyl and organic peroxides

2. Flammable substance

Metal lithium, potassium, sodium, yellow phosphorus, phosphorus, sulfide, red phosphorus

Gelatin, calcium carbide (calcium carbide), calcium oxide (lime), magnesium powder, sodium hydrosulfite (sodium hydrosulfite) (sodium hydrosulfite)

3. Oxidizer

Potassium chloride, sodium chloride, ammonium chloride, and other chlorides (Powder)

Potassium perchlorate, sodium perchlorate, ammonium perchlorate, and other high chlorides

Potassium nitrate, sodium nitrate, ammonium nitrate, and other nitrates

Potassium peroxide, sodium peroxide, barium peroxide, and other inorganic peroxides

Sodium chlorite and other chlorites, calcium hypochlorite and other hypochlorous substances

4. Flammable substances

2、 Ether, gasoline, acetaldehyde (acetaldehyde), propylene oxide, propylene oxide, carbon disulfide, and other substances with ignition points between -30 ℃ and 0 ℃

Methanol, ethanol, xylene, benzyl, benzyl acetate, and other substances with ignition points between 0 ℃ and 30 ℃ (alcohols)

Lamp oil, kerosene, gasoline, isoamyl alcohol, acetic acid (acetic acid), and other similar substances with ignition points between 30 ℃ and 65 ℃

5. Flammable gases (hydrogen, acetylene, ethylene, methane)

Ethane, propane, butane, and other gases at 15 ℃ and one atmosphere

2、 When liquids containing salt leak or overflow, they must be wiped clean in a timely manner, and the sealing ring along the lid must be wiped dry, otherwise it will corrode the container and pipeline

3、 Before opening the lid, confirm that the pressure has fallen below "0/npa"

4、 Do not modify this product without authorization

5、 Do not use this instrument near explosive gases

CAUTION CAUTION CAUTION:

1. Foreign substances or liquids entering the discharge hole can cause ignition or power failure when operating the instrument

2. Do not touch the power cord casually, and do not press heavy objects on the power cord. Exposed damaged wires or metal wires can cause power outages or fires

3. Do not pour any liquid into the container except distilled water

4. Do not use this high-pressure steam sterilizer for disinfection and high-pressure undissolved agar for other purposes (Powder)

5. Check if there are any foreign objects adhering to the gasket of the lid. If there are any foreign objects, they should be removed in a timely manner, otherwise it may cause steam leakage

6. Please use the matching tools and do not use other baskets in the sterilizer

7. When under high pressure, be careful not to burn when taking out items after high pressure

8. If any abnormalities occur (such as sound, smell, or smoke), please immediately cut off the power Engineer, eliminate any abnormalities before continuing to use

9. Please lock the lid when moving this instrument When moving the lid, do not pull the handle of the lid, otherwise the lid will deform and it will be difficult to cover tightly
