In the earth and more precisely in the workstations, many microbes circulate. Nevertheless, the products shaped have to be endangered from these damaging particles. It happens to be for this reason that the products have to be handled in sterile conditions to fight against the dangers of cross-contamination correctly.
Laminar flow hoods are workstations with a built-in air filtration system used for a variety of applications. Laminar flow hoods provide the work area with a gentle stream of air with laminar flow and class 100 conditions (ISO class 5). They are virtually a particle-free work area that will protect the sample from any contaminants in the environment. Air filtration is obtained using a built-in HEPA filter, which filters out 99.99% of particles greater than or equal to 0.3 microns. This equipment protects the sample explicitly and not the user and should never be used with pathogens or volatile or toxic chemicals. The Six Feet Free Standing Horizontal Laminar Flow Hood has a large work area with glass side walls, illuminated by a fluorescent lamp.
- Pharmaceutical production areas
- Planting plants
The exterior is made of a black sheet coated with white plasticized electrostatic paint (complete equipment manufacturing option with stainless steel).
The work area is constructed of AISI 304L stainless steel, glass side panels and a ceiling where the UV and fluorescent lamps are located.
Laminar flow hood, what is it?
A laminar flow hood is a countertop that prevents contamination of harmful particles and vapours from the products being handled. Consequently, the manipulations use to be carried out below sterile conditions, and the products happen to be endangered from bacterial contamination of biological examples. The laminar flow hood used to be used mainly to make culture media and for inoculating a substrate.
Method of laminar flow hood functions
The laminar flow hoods use to be made to make a work unit with zero particles. It brings in the air through a very well-organized filtration system and relinquishes the air through the work surface in the uni-facial airflow. Manifestly, the ambient air can be sucked in by a turbine before passing through a HEPA filter to come to the workspace finally. Once the filter used to have been passed by, the air no longer comprises particles: yeast, dust, spores, or bacteria. Thus, the air happens to be seen as sterile.
The Laminar Flow Hoods typically use a UV-C lamp result germicide for sterilizing the work strategy and its element. You have to turn off the said lamp when you are working under the hood not to be a victim of skin cancer or cataracts. Nevertheless, before you proceedwith using the hood, you have to sterilize your hands and the entire of your apparatuses so by way of not contaminating your culture. Also, avoid as much as you can storing objects on the worktop of the hood to promote sterilization.
What to choose between horizontal and vertical laminar flow?
The horizontal or vertical laminar flows make it possible to effectively protecting the products in contradiction of the particles. With horizontal laminar flow, particles use to be completely evacuated with not there as any turmoil on the work point. Thus, the samples placed in the work area can no longer be contaminated. Also, the bottom of the hood is well sterilized by the unidirectional airflow thatempties the particles outside. The vertical laminar flowhelps ensure desired air quality over the entire work surface. It also evacuates particles, but turbulence can be noticed in the area of the worktop. The desired efficiency here uses to be for the entirevolume, thusconsidering the depth, width, and height.
How then to choose?
This is the question that arises. Here are some simple methods that can help you choose your laminar flow hood. First, select the type of hood that is right for your use. You can easily choose after reading the explanations already discussed. Ask chemists for advice if you want to know more about the technical characteristics. Then, opt for a brand that has notoriety in this sector. Browse customer reviews of the manufacturer to find out its integrity and the quality of its products.
