About the safe use of laboratory infrared sterilizers
At present, more and more hospital inspection departments, pharmaceutical factories, and disease control centers consider the use of infrared sterilizers instead of alcohol lamps for disinfection from a safety perspective. This simple instrument with no open flame operation has been loved by major scientific research units, and domestic famous brands. The zanghan brand combines the opinions of major hospitals. The 2013 model incorporates the intelligent temperature alarm system. The user-friendly design and one-button operation save you time and worry!
Zanghan brand infrared sterilizer is divided into two sizes: ZH-4000A infrared sterilizer, ZH-4000C infrared sterilizer, two calibers and cavity lengths are different, can be equipped according to experimental needs, in each biological safety cabinet Designated standard equipment, welcome to choose zanghan brand, safe and reliable quality is guaranteed!
　　
The flame heating or burning sterilization devices commonly used in the laboratory include alcohol lamps, Bunsen burners and infrared sterilizers. In this chapter, we will focus on the use of infrared sterilizers and their precautions.
First, the use of infrared sterilizer sterilization considerations:
1. When observing the bacterial form from the specimen or culture in question, an inoculating loop must be used. The inoculation ring system is made of a nickel wire or a special platinum wire having a moderate hardness of about 5 to 8 cm and placed on a metal or glass rod. Those who have a loop are called inoculation needles.
2. The inoculation ring or inoculation needle should be sterilized by infrared sterilizer before and after each use. That is, it is thoroughly cauterized once in the infrared sterilizer, and the metal rod or the glass rod portion in the infrared sterilizer chamber must also be rotated for sterilization.
3. After the inoculation ring (needle) is sterilized by infrared sterilizer, it needs to be cooled before taking the specimen or placing it on the workbench to prevent scalding the microorganisms and burning the table. (Cooling time is the same as traditional alcohol lamp time).
4. Infrared sterilizer can also disinfect the microbial culture tube of glass material. At this time, pay special attention to the fact that there should be no liquid or other objects in the tube to avoid dangerous accidents such as liquid spillage or explosion.
5. After the non-stained specimen and the stained specimen are observed, they should be sterilized immediately into the disinfectant.
6. If you have used a slide, you must completely remove the stained bacteria on the slide, otherwise you may make a wrong diagnosis when you use it again.
Second, the small knowledge about infrared sterilizer:
How to judge the quality of an infrared sterilizer Zui is mainly heating body, infrared sterilizer heating body -- it is the main component of the infrared sterilizer, the effect of sterilization is great. Heating body failure is one of the main reasons for the decline of sterilization effect, which is mainly manifested by a decrease in heating rate; affecting heat distribution; and generating dust. The cause of the heater failure is mainly caused by the long-term use of the heating body or the poor air quality of the heater and the quality of the purchased infrared sterilizer itself. Therefore, we must look for the purchase when choosing an infrared sterilizer, and do not affect the entire experiment.
