Shanghai Xinzhuang Instruments teaches you how to choose a good performance anaerobic incubator (or anaerobic workstation), and it has become a hot topic in related fields. The anaerobic incubator selection index anaerobic state stabilized anaerobic incubator has both anaerobic operation functions. The anaerobic state stability includes: 1. The anaerobic incubator has good air tightness, so that the operation and maintenance state, the inner cavity of the box It is in a stable anaerobic level. 2. The operation hole is designed reasonably. It is easy for the operator to get in and out of the box while reducing the chance of the outside air entering the anaerobic cavity, ensuring the stability of the inside of the box when the hand is out. Oxygen level; 3, the transmission cabin design is reasonable, in order to facilitate the rapid entry and exit of the sample into the box, it also reduces the opportunity for outside air to enter the anaerobic cavity, to ensure the stable anaerobic level of the chamber cavity when the sample is transferred. The high-performance material (strong anti-aging ability) anaerobic incubator can reduce the risk of aging, cracking and leakage of the outer wall, and ensure anaerobic stability under normal conditions. The quick and convenient operation of the operating hole and the transmission chamber design and the positive pressure of the lumen are scientific designs that reduce the chance of outside air infiltrating into the lumen during hand-in and out-sample transfer. This factor should be considered as an indicator. Stable anaerobic bacteria culture should be carried out in a stable temperature environment. The temperature stability of the anaerobic incubator directly affects the reliability of the culture results.

The temperature system of the inner cavity is realized by gas convection, and the good inner cavity convection design is the key technology for temperature stability. The anaerobic bacteria in a stable state should be cultured in a suitably stable humidity environment. Excessive or too low humidity environment can easily cause the occurrence of bacterial atypical biological traits, which directly affects the judgment of the identification results. In addition, since the anaerobic incubator is a closed inner cavity, a large amount of medium evaporation of water easily causes the generation of condensed water, and on the one hand, the condensed water is a cause of biological contamination, and on the other hand, the bacterial colonies are easily disappeared (flaky Growth), both cause culture failure. Therefore, efficient humidity control should also be the key to humidity stability. Anti-pollution ability Because the anaerobic incubator has the dual functions of operation and culture, the disinfection of the inner cavity is very important for the success of the experiment. The ability to support UV disinfection and disinfection of strong oxidizing disinfectants is essential. High-performance anti-aging materials allow UV disinfection and strong oxidizer disinfection to meet the sterilization and sterilization needs of routine and special conditions in the anaerobic incubator chamber and should be a priority.

All bacteria with biological detoxification function, including anaerobic bacteria, produce metabolic waste during the growth and reproduction process, and a considerable variety of anaerobic bacteria can produce metabolic waste gas. In the closed cavity, the concentration of metabolic exhaust gas gradually increases, and finally inhibits the growth and reproduction of the living bacteria. Effective removal of metabolic waste gases (biodetoxification) is an important guarantee for ensuring good growth of anaerobic bacteria.
