When constructing a laboratory specifically for extraction processes, there are a great many additional factors to take into consideration above and beyond those of a standard laboratory. Obviously, you need to take into consideration the overall dimensions and shape of the room, as well as any relevant building codes and even any applicable fire regulations. Is it necessary to create a negative pressure in the space? Does pcr machine (see more) need to be sterile? Do you have access to a power supply that is large enough to run all of the necessary machinery?
Considerations Should Be Made Regarding Ventilation and Space
During the process of building out the space, you are required to conduct a risk assessment. This assessment should take into consideration the materials you are working with as well as whether or not the space needs to be electrically classified as a Class I Division 1 or 2 space. This responsibility falls on the Chemical Hygiene Officer of your company. If the room is classified as Class I Division 1 or 2, which happens to be quite common, you will need an explosion-proof fume hood rather than a regular hood to ventilate the area. The construction of an explosion-proof hood involves taking extra safety measures to reduce the likelihood of sparks igniting a fire or starting an explosion. Other aspects of fire protection, such as sprinklers and other extinguishing systems, static grounding systems, and means of egress, must also be taken into consideration.
The evaluation of the mechanical system is an extremely important component of the selection process. Is nano spectrophotometer capable of meeting the CFM requirements of the fume hood (or hoods) in your lab's extraction area? Is it able to supply an adequate amount of conditioned air to replace the conditioned air that is being lost? You need to make sure that your fume hood can be supported properly or you run the risk of not properly exhausting the fumes. The size of the hood you require can also be determined by calculating the CFM requirements of your system.
Also consider how you will bring the hood into the laboratory when making your plans. Even though they frequently arrive at their destination in separate pieces, floor-mounted hoods are still very substantial. The building must have the capacity to accommodate their size, which presents a potential challenge from a logistical standpoint.
When planning the layout of the laboratory, you need to make sure that there is sufficient space to house and operate the extraction equipment, which is typically quite large. In general, extractors stand at a great height. Because micro spectrophotometer is necessary to protect them by placing them inside a fume hood, you will need a fume hood that is significantly taller than usual. Because a hood that is mounted to the floor is required here, it is absolutely necessary that there be sufficient space between the floor and the ceiling for the hood and the ductwork that it requires.
When it comes to ventilation, the area close to the floor is an important focal point for floor-mounted hoods. The ASHRAE 110 test methodology known as the "flow visualization procedure" is utilized in the process by which fire marshals validate that the installation is operating as intended. This includes the proper management of hoses and cables inside the hood in order to avoid potential areas of dwell among the hoses and cords. This issue needs to be resolved before the vehicle can be certified as final and put into use. The presence of an excessive amount of cords and hoses on the floor of a fume hood can result in the formation of dwell patterns on the floor of the hood, which will cause the airflow pattern visualization test to be failed.
You have chosen an explosion-proof, floor-mounted hood as the final candidate in your hood selection process. So what do we do now?
Think about the various add-ons and components that will be necessary for your process. Do you require any service fixtures, such as those for gas, air, water, or anything else? In most cases, there will be lines that are run into the hood in order to supply the material that is being used in the extraction. Pneumatic stirrers that are explosion-proof are frequently used in place of equipment that is powered by electricity. Do you need to install pass-through ports in the hood in order to provide them with easy access to the extraction equipment? Do you require an airflow monitor in order to guarantee the correct CFM? Which type of sliding sashes do you require: horizontally sliding ones that move left and right to allow the full height of the hood but only partial width, or vertically sliding ones that move up and down to allow the full width of the hood but only partial height?
Equipment Location
It is essential to position the hood in the correct manner. Is it going to be in close proximity to a door or a vent? Will there be a lot of people passing through the area? Be ready to address these issues as they pertain to airflow and the requirements for airflow that are necessary for your extraction process. Because hoods used for extraction require an unusual amount of plumbing and electrical supply to each hood, the space between hoods (especially in the case of floor-mounted hoods) can be extremely important.
Equipment for multiple stages of extraction, such as explosion-proof floor-mounted fume hoods, is available for purchase from Labconco.
