Simulated growth environment in a carbon dioxide incubator
A carbon dioxide incubator, one of the most commonly used conventional instruments in the laboratory, is widely used in medical, immunology, genetics, microbiology, agricultural science, pharmaceutical research and production.
The product of Shanghai Jianhu Instrument Equipment Co., Ltd. is an advanced instrument for the cultivation of cells, bacteria and microorganisms; it is an essential product for the research and production of immunology, genetics and bioengineering pharmacology. It simulates the formation of a similar cell/tissue growth environment in the living body such as constant pH (pH: 7.2-7.4), stable temperature (37 ° C), and high relative humidity (95%) in the incubator. ), a stable CO2 level (5%), a device for in vitro culture of cells/tissues.
Two control systems: infrared sensor (IR) or thermal conductivity sensor (TCD) for measurement. Both sensors are accurate, but each has its own advantages and disadvantages. The working principle of the thermal conductivity sensor to monitor the CO2 concentration is based on the continuous measurement of the thermal conductivity of the internal cavity air. The low thermal conductivity of the input CO2 gas will change the thermal conductivity of the air in the cavity, which will directly produce a concentration directly with the CO2. A proportional electrical signal.
Infrared sensor (IR) It uses an optical sensor to detect CO2 levels. The IR system includes an infrared emitter and a sensor. When the CO2 in the tank absorbs part of the infrared light emitted by the emitter, the sensor can detect the amount of infrared radiation, and the amount of absorbed infrared light corresponds to the level of CO2 in the tank. Thus, the concentration of CO2 in the tank can be obtained.
Since the IR system determines the CO2 concentration in the tank by infrared reduction, and the particulate matter in the box can reflect or partially absorb the infrared rays, so that the IR system is sensitive to the amount of particulate matter in the tank, the IR sensor is applied to the cultivation with the HEPA high efficiency air filter. The box is more suitable.
Eyelet Machine,
This machine is used for punching,binding and riveting the eyelets on the papers in one operation with the eyelets feeding automatically in high efficiency.Once riveted, the eyelets will not easily broken off and are looking nice and smooth on the products without any scratches.
The eyelet machines are widely used for paper bags, paper boxes, cartons, archive bags, document bags, secret documents, files, certificates, cards, hangtags,box seal and so on.
Features,
1.The machine can automatically punch or continuously punch and rivet eyelets.
The punching and eyeletting can be finsished in one operation.
2.adjust hole distance freely according to the requirement.
3.The riveted shoes holes are are neat, beautiful and ametabolic with no scratches.
4.Easy operation and reliable performance.
5.The efficiency is 8-15 times than manual operation.
