Precautions of Using High Pressure Sterilizer

Note: completely exclude air in the pot, so that the pot is full of water vapor , can be completely sterilized . There are several different approaches of releasing vapor out of autoclaving , but all purpose is to drain the air, so that the pot can be evenly heated , to ensure thorough sterilization . Common methods are: close the release valve , energized, until the pressure rises to 0.05MPa , open valve , release the air until the pressure gauge pointer back to zero , and then close the valve . Off valve reenergized, the pressure gauge reaches up to 0.1MPa, start ticking, maintain the pressure 0.1 ~ 0.15MPa for 20 minutes.
When holding time arrive , you can turn off the power , the pressure drops to 0.5MPa, release steam slowly, the pressure reduction should not be taken too fast , or resulting in a heated pressure boiling , the liquid overflowing the container . When the pressure drops to zero only after opening the lid , remove the culture medium , place on the platform , to be condensed. Can not hold the vapor for long , causing changes in medium composition , as well as the medium can not be put slope. Once place for too long , since there is a negative pressure inside the boiler , lid can not be opened, as long as the release valve opens , pressure into the internal and external pressure balance , the lid will be easily opened.
Right after autoclaving non-perishable items such as sterile water, growing medium , inoculated with utensils, sterilization time can be extended or increase pressure . The medium to strictly observe dwell time , it is necessary to dwell thorough, but also to prevent deterioration of the medium composition or lower the effect, just do not extend the time.

How to Choose Imported Autoclave

How to Choose Imported Autoclave

Its use of imported autoclave safety and automated processes, much loved by laboratory users. So, how to buy desirable products? How to distinguish which products are imported? Which products are assembled inland? The following will tell you how to choose imported autoclave:
Before purchasing imported autoclave, first you need to understand, import autoclaves, especially more than 50 liters of imports autoclaves, special equipment in China, before use , the user needs to check the local special equipment agency ( or pot seized by , or Technical Supervision , according to the actual situation around ) handle license. When applying for a license, required to submit a certificate include:
First, the ” inlet pressure vessel manufacturing license “, referred to the pressure vessel license. This license is the manufacturer of the pressure vessel to the Chinese bid for Quality and Technical Supervision , each instrument will be attached a random number with a similar fuselage pressure vessel manufacturing license ;
Second, the ” Import and Export boiler and pressure vessel safety inspection certificate”, this certificate should be imported in the customs , the declaration by the importer , the Customs notify the relevant special equipment testing organization for the import customs inspection, some areas, or by the user to the goods within 30 days of special equipment testing organizations to the local bid . This certificate is for the fees.
Third, users need to cannibalize autoclaves and pressure relief valve on the pressure gauge, sent to the local metrology measurement obtained after measurement certificate.
