The laboratory cabin exerts the protective action on the scientist from infectious risk, on the pollution environment, on the sample with which microbes are worked, It is used to make the barrier against the contaminating material. Generated in the places of experimentation.
What is a Laboratory Cabin?
They are cavities created as a circulating air chamber restricted, they provide various types of protection. They are fundamental in the laboratories of chemistry, microbiology, biology etc. It has different levels and kind of care it provides. A piece of equipment that has been designed for the control in the experimental spaces. Where they are neutralized, the particles related to the handling of biological material. With threat of being toxic and infectious. The atmospheric pressure and the current are controlled of air.
laboratory cabinets on the market
Three types are considered which are: The bell of extraction of gases, it constitutes a hermetic enclosure that captures the smoke or steam issued by the handling of chemicals. The laminar flow booth, it consists of a high efficiency particulate air (HEPA) filter which with the help of a fan, it leads the air to said filter. Cleaning the entire cabin. Its function is to keep the air clean of pollutants. Security the cabin, they are like a mini-room with special ventilation to put limit to the risk of infectious agents.
Types of laboratory booths
Class I, type A, provides protection to the operator and the environment. It can work with pathogens of level 1, 2 and 3. System HEPA is located in the extraction. Type B1, CLASS II, also provides safety to the worker and the environment. It is suitable for working with level 1, 2 agent and 3. The HEPA system has two filters, it works by extracting through a duct the contaminated air, recycles it in the cabin and then filters it after taking in air from outside. It works small amounts of pollutants.
Class II, Type A, provides protection to the manipulator, the environment and the product. It works with pathogens of level 1, 2 and 3.The HEPA it has two filters one located on the surface where it is worked and another on the removal of the cabin. Type B2.Class II, protects the one who manipulates it, to the environment and the product. Work with agent level 1, 2 and 3. HEPA System
it performs the total extraction of the internal air from the cabin. Work with chemicals toxic and radioactive. Third class, protects the environment, the operator and the product.
The HEPA consists of two filters, one for extraction and one for intake. Cleans type 4 pathogens. The cabin is all sealed. Both the entry and exit of the material is carried out by a double-pass box. At the door for material handling is executed with gloves glued on the front of the cabin. Class II, Type B3 - A/B3, offers protection to the sample handler, the environment and the producer. Cleans pathogen of type 1, 2, 3. Its HEPA system has two filters. It has a combined cabin because they are joined by a duct that recycles the air 70% inside the cabin.
Laboratory Booth function
Most are deployed by the fact of the construction of a space where no contaminating pathogenic agent can escape to the provide a work space with very little chance of escape from contaminating substances to the environment, protecting the operator, the area that surround t to the product.
The gas extraction cabin or hood has a function of capturing the gases or vapors of corrosive substances and irritating. The horizontal laminar flow booth provides shelter to the product, but not limited to those that have risk or danger to the operator. The vertical laminar cabinet, ensures the safeguarding of the product and the manipulator.
It uses dangerous pathogens. The biological safety cabin, maximum utility in microbiology. Keep the area free of contaminants from bacteria, yeast without access to the culture.
Laboratory Booths price In the media electronic se they find a variety of prices that can be adjusted to your economy. Nail laminar flow hood for pharmacy, used 1.600.000 bs. A bell of industrial laminar flow, used has a cost of 1,000,000 bs. A cabinet of biosecurity from 800 to 1800 dollars. Chemical laboratory of biotechnology since 800 to 1,600 dollars. Cabin made of glass from 1,500 to 2,000 buck. Biobase security cabinet from 1,000 to 5,200 dollars. Biobase Chinese class II B2 from 2900 to 3,150 dollars. Mini cabinet biobase of security from 100º to 1430 dollars.
Laboratory booth application
To use the cabinet should be followed the following:
- Make a planning about the work to be executed.
- The time, the procedure of the use thereof.
- Comply with the basic rules for the use of the cabin.
- Lights on, fan, grilles unlocked, accommodate the area to where it will be worked. Let this one work alone for a quarter of an hour. Perform the rite of body disinfection, dress protective clothing if needed. Do the disinfection of the area inside the cabinet.
Load and install the necessary material. Place a biosecurity bag for waste, monitor the cleanliness of all used material. Finally, let the cabin be swept for five minutes to eliminate the particles produced. When starting activities, introduce your hands carefully and slowly. Do the tasks gradually following the methodology. Work from the contaminated areas to the less polluted, place the materials and samples 10 to 20 cm behind the front grid. The test much more polluting place it towards the bottom of the area.
Do not use a cigarette lighter in the laboratory cabin. Do not remove your hands from the work area until the experiment is over. Proceed to cleaning the cabin for 5 minutes. Disinfect the area, materials or equipment used. Throw away all disposable work clothes. Wash your hands frequently. Turn off the fan, the lamp, close the front of the cabin, turn on the ultraviolet lamp.
