What Are the Different Types of Laboratory Supplies?

Laboratory equipment is popularly described as laboratory-specific furniture, which has developed with the deepening of reform and opening up and economic development, the needs of national inspection institutions and the improvement of corporate R & D awareness.

Laboratory equipment

Laboratory equipment can usually be divided into:

The main characteristics of laboratory equipment are: the main materials must be resistant to acids and alkalis,

With the development of the economy, more and more laboratory fume hoods are used. Due to the large number of fume hoods, which are poisonous, harmful and odorous, their energy consumption is 5-8 times that of ordinary office places, so their ventilation schemes need to be more strict and reasonable. To put it simply, there are generally two solutions of variable frequency control system (PLC) and variable air volume control system (VAV).

The variable frequency control system (PLC) can play a role in discharging toxic and harmful gases and saving energy to a certain extent. However, when the number of fume hoods is large and complex conditions such as synthesis or laboratory room temperature control requirements are involved, it cannot be strictly and effectively controlled. Surface wind speed and ventilation volume are actually difficult to achieve a completely effective effect.

The variable air volume control system (VAV) is an important component of air conditioning systems. It has great energy saving potential, and also has a complex control system and complicated equipment. The application of this system in the laboratory mainly uses some technical means to effectively control the surface wind speed of the fume hood.

The surface wind speed index of the fume hood is about 0.5m / s is the most basic element to ensure effective emissions. In other words, only by ensuring the surface wind speed is relatively constant, can the laboratory safety and environmental comfort be ensured and achieved.

Another advantage of the variable air volume control system (VAV) is that it can save 30% -50% of energy, and the use effect of places with large and long-term ventilation requirements is more obvious.
