Have you found your own laboratory Biosafety Cabinet yet?
When we choose laboratory Biosafety Cabinet and determine the location of its installation, according to the experimental content to choose from. Generally consider the following factors:
Material: In the use of special acids for experiments, the selection of Biosafety Cabinet taking into account its material. Such as the corrosion industry or the semiconductor industry, we must use anti-corrosive materials made of Biosafety Cabinet.
Dimensions: According to the experimental content to select the required dimensions, otherwise the volume will cause excessive waste, too small will affect the experimental use. Especially when using large equipment for experiments, it is necessary to fully consider its internal effective size and leave some room for exhaust ventilation.
Save energy: try to think about energy savings. As in the heating or air conditioning space should be used air-filled Biosafety Cabinet or biological control cabinet with air volume control. In the choice also need to determine the power, should not blindly increase the exhaust volume or pressure can be used by variable speed fan or inverter to reduce power consumption.
Environmental Protection: Biosafety cabinet exhaust harmful gases must ensure that the national environmental requirements below, if more than the national health standards, should install or replace the corresponding biological biosafety cabinet purification device.
At the same time, the Biosafety Cabinet should be installed in a public place avoiding the road or the concentration of personnel, avoiding the blockage of the windows or the poor ventilation and lighting. In the modern research laboratory, the advanced and perfect experimental equipment and good and safe experimental environment are the necessary conditions to improve the scientific and technological level and promote the scientific research achievements. The Biosafety Cabinet as one of the important facilities in the biochemical laboratory plays a decisive role, so we must carefully choose to meet the technical indicators and their own Biosafety Cabinet.
The safety function of Biosafety Cabinets is a demand-guarantee industry. Due to the catastrophic damage caused by the tests and scientific researchers that are now used in the safety of Biosafety Cabinet, In many surprises, laboratory loss or damage due to defeat of Biosafety Cabinet or temporary collapse. The safety features of Biosafety Cabinet are planning elements that demand attention.
In the safety planning, in addition to regular replacement of biosafety cabinet indoor decontamination data deformation and regular cleaning of pipes, the appearance and internal planning also need to think about the Biosafety Cabinet more scientific and rational planning, it is necessary to consider the following elements: Biosafety cabinet exhaust The equipment should be provided with slotted exhaust to ensure that the release of toxic gases will not affect the optimal decontamination of Biosafety Cabinet that scientists and researchers are testing and accurately purifying the discharge pipes with ventilation.
Biosafety Cabinet are generally divided into the row of Biosafety Cabinet and non-pipeline Biosafety Cabinet. Non-pipeline Biosafety Cabinet is the use of activated carbon filters, the experimental operation will produce toxic gases directly adsorbed. The saturated filter is not properly adsorbed toxic gases, which can not achieve the protective effect. Therefore, after using a certain period of time to filter the saturated state of regular inspection. If it reaches the saturated state, it should promptly contact the product manufacturer to change it;
When the Biosafety Cabinet starts to run, it can not be moved, and certainly it is not allowed to probe into the Biosafety Cabinet for experimental operation. Personnel should have a distance of more than 15cm from the Biosafety Cabinet. At the same time in the Biosafety Cabinet can not be surrounded by other equipment, the surrounding space should be as spacious and comfortable to ensure that it can operate normally, excluding toxic gases. Otherwise it will result in non-uniform airflow, can not rule out toxic gases, and outdoor fresh air will not be able to enter the laboratory for circulation.
