Buying points for anaerobic incubators

The purchase points of the anaerobic incubator First, the stability of the anaerobic state includes: 1.
The anaerobic incubator has good air tightness, so that the inner cavity of the box is at a stable anaerobic level under operation and maintenance; 2.
The design of the operation hole is reasonable, which is convenient for the operator to enter and exit the box with both hands, and also reduces the opportunity for the outside air to enter the inner cavity of the anaerobic incubator, ensuring the stable anaerobic level of the inner cavity of the box when the hand enters and exits; 3.
The design of the transfer chamber is reasonable, which facilitates the rapid entry and exit of the sample into the box at the same time, but also reduces the opportunity for the outside air to enter the inner cavity of the anaerobic incubator, and ensures the stable anaerobic level of
the inner cavity of the box during sample transfer.

The anaerobic incubator with high-performance material (strong anti-aging ability) can reduce the risk of external wall aging cracking and air leakage, and ensure anaerobic stability
in the normal state.

The quick and easy operation hole and transfer chamber design and the design of the cavity positive pressure are scientific designs
that reduce the chance of outside air infiltration into the inner chamber during hand in and out and sample transfer.

This factor should be taken into account
.

Second, the temperature state is stable The cultivation of anaerobic bacteria should be carried out in a stable temperature environment, and the temperature stability of the anaerobic incubator directly affects the reliability
of the culture results.

The temperature system of the inner chamber is achieved by gas convection, and good internal cavity convection design is the key technology
for temperature stability.

Anaerobic incubator purchase index - stable humidity state The cultivation of anaerobic bacteria should be carried out in an appropriate and stable humidity environment, and too high or too low humidity environment is easy to cause the emergence of atypical biological traits of bacteria, which directly affects the judgment
of identification results.

In addition, because the anaerobic incubator is a closed inner cavity, the evaporation of a large amount of medium water is easy to cause the generation of condensate, and the condensate is the cause of biological pollution on the one hand, and on the other hand, it is easy to make the bacterial colony disappear (flake growth), which leads to culture failure
.

Therefore, the efficient humidity control function should also be the key
to humidity stability.

Third, anti-pollution ability Because the anaerobic incubator has both operation and cultivation dual functions, the disinfection of the inner cavity is crucial
to the success or failure of the experiment.

The function of supporting UV disinfection and disinfection with strong oxidation disinfectants is a must
.

High-performance anti-aging materials allow UV disinfection and strong oxidant disinfection to meet the sterilization needs of the inner chamber of anaerobic incubators, which
should be considered first.

Fourth, biological detoxification function All bacteria, including anaerobic bacteria, will produce metabolic waste in the process of growth and reproduction, of which a considerable number of anaerobic bacteria can produce metabolic waste gas
.

In the anaerobic incubator, the concentration of metabolic exhaust gases gradually increases, inhibiting the growth and reproduction of
live bacteria.

The effective removal of intraluminal metabolic exhaust gases (biological detoxification) is an important guarantee
for ensuring good growth of anaerobic bacteria.

Therefore, having biological detoxification function has a great impact on the quality of anaerobic bacteria culture, which should be considered as an index
.

Fifth, easy to operate the anaerobic incubator is different from the clean bench (or biological safety cabinet), which requires the operator to complete the operation in a closed working chamber through the observation window, and requires the hand in and out and the process of sample transfer as fast as possible to ensure the stability
of the anaerobic state of the inner cavity.

The scientific and reasonable design of the transmission chamber, the operating hole, and the permeability of the observation window are all what the high-performance anaerobic incubator should have, and it is also an important basis for
considering its performance level.

The use of inoculation rings or inoculation needles for inoculation, transcoding, picking up a single colony and other microbial routine operations are fine actions, operators have higher requirements for hand feel, so the operation mode of the whole glove will be far behind the naked hand operation in this regard
.

High-performance anaerobic incubators should be capable of bare hand operation
