1. Lab chair
According to the experimental requirements, the work chair can be made of steel and wooden. For the convenience of the experiment and space saving, usually with stool. If the stool is made of steel, it can also adjust the height. A instrument laboratory with a pulley chair is easy for operation.
2. Laminar airflow cabinet
Laminar airflow cabinet is also called lab balance table, widely used in biology, medicine, health, electronics, precision instruments, instrumentation and other industries. Provide aseptic and dust-free clean operating environment.
The structure and working principle of the laminar airflow cabinet : the main parts include cabinet body, operation table, front panel, fan, static pressure box, filter, lighting lamp, germicidal lamp, etc.. The external gas blower, gas pressure of the work area is positive to ensure that the work area will not be affected by external gas pollution. Laminar airflow cabinet can be divided into horizontal and vertical laminar laminar flow according to the direction of gas flow, the specifications are single, double, single, double, also can be used in series.
3. Bio safety cabinets
The biological safety cabinet is widely used in academies and research institutes, pharmaceutical, health and epidemic prevention unit, it is main clean equipment used in microbial experimental operation; it can prevent the spread of possible toxic and harmful particles in suspension;it protects the safety of operator and the environmental in the process of safety;it can also protect the sample from contamination during operation.
The level of bio safety cabinets
Level 1: function as a detoxifying cabinet with a filter to protect the operator and the environment.
Level 2: simultaneously protects operator, environment and samples for biological safety 1, 2, and 3 samples.
Level 3 : at the same time protects the operator, the environment and samples, the operating
environment is completely isolated with the external environment , with glove box, full closed
operation, applicable to high risk samples of the experimental operation.
The main difference between bio safety cabinet and laminar airflow cabinet:
The bio safety cabinet is mainly to protect the operator and environment, also can protect the sample, its structure is more complex than laminar airflow cabinet. In the operating area,the pressure of gas is negative. Gas will be discharged after purification ; laminar airflow cabinet protects operation samples, does not protect of the operator and the environment, gas pressure of the operating area is positive , gas discharges directly outside the operating area.
