Hood Calibration

A laboratory hood, also known as a chemical laboratory hood, is a local ventilation device designed to limit the laboratory operator’s exposure to toxic fumes, dust, fumes, and toxic particles. Captures and removes them. These hoods are designed to be connected to an exhaust system that draws air out of the room and are commonly used in laboratories where toxic chemicals are tested, researched, or trained, as well as used. Industrial goods are released.

A laboratory hood is a large, 5-sided box-like structure with an open wing (or wings) that allows laboratory personnel to access the interior of the laboratory hood, which is often placed on the work surface. The lab hood has a transparent removable panel that allows the user to narrow or widen the lab hood hole by moving it up or down. Most hoods are equipped with a control panel that warns of low or excessive airflow in the front of the device, or provides a mechanism to turn the output fan on or off. This lab hood may have built-in lamps with anti-fog covers to illuminate the environment. There are two main types of laboratory hoods, without duct or with duct. A laboratory duct hood has a filter to clean the air before circulating it back into a room, while a duct laboratory hood relies on a fan system that directs air out of the building through the duct function. Slowly

A laboratory hood may be made of plastic, such as polypropylene, or powder coated steel for chemical resistance. Their width is usually in 5 categories: 1000 mm, 1200 mm, 1500 mm, 1800 mm and 2000 mm. This laboratory hood may have a depth of 700 to 900 mm and a weight of 1900 to 2700 mm. The laboratory hood is usually leaned against a wall for use, either on a table or on the laboratory floor. Test versions of these hoods may have clear sides so that several students can immediately view the experiments. Laboratory hoods to limit exposure to vapors, dust, smoke, and toxic particles in medical and industrial laboratories. And research as well as educational collections are used.

Laminar laboratory hood

The Laminar Laboratory Hood is an enclosed area designed to protect personnel and specimens. Air enters through a HEPA filter, which removes contaminants and / or toxic particles in such a way that a flow of air is then directed to the user. These hoods are used in medical, research, and pharmacological laboratories to evaluate and develop drug development methods. These units can be fixed or portable, made of different materials such as stainless steel and acrylic and have different dimensions. Choosing a laboratory hood will depend on the budget, available space, application, type of filter and required light. Look for features such as chemical resistance, lockable, wire racks, adjustable speed, ergonomic design, blower features and low noise.

PCR laboratory hood

The PCR laboratory hood is a work space that is enclosed in three wings and provides space for DNA or RNA expansion. PCR hoods are used in biological and genetic laboratories and therefore do not expose any contaminants to the sample. PCR hoods have no air circulation, which helps prevent contamination, and have UV lamps for sterilization. Features that vary between PCR hoods include the size, presence or absence of a HEPA filter, and whether or not they have a timer for UV sterilization, so consider your needs before you buy.

Class 2 biosafety hood type B2 / tissue culture hood (biosafety hood)

To protect researchers from potentially hazardous specimens and specimens from contamination, Type B biosafety hoods consist of three-sided workplace vents with a positive pressure, and in microbiology laboratories, laboratories Toxicology, and research laboratories that contain pathogens and toxic chemicals are used in the workplace, while protecting specimens from contamination by the outside environment of a biosafety laboratory hood that can contain tissues. And cell culture media. The air drawn into this type of laboratory hood is absorbed into a HEPA filter and then all of this air is expelled through another HEPA filter, instead of circulating it again inside the hood or Take it out into the lab.

Class 2 biosafety hood type A2 / tissue culture hood (biosafety hood)

A Class 2 Biosafety Laboratory Hood is a small enclosed workspace designed to protect the operator, the environment and the materials inside. Class 2 biosafety hoods have open fronts, a vertical laminar flow of air, so air outside is directed through a filter before it enters, and a HEPA filter to filter air from the inside beforehand. There is a way to get out of the lab hood. These hoods are used in microbiology laboratories, pharmacological laboratories, and research laboratories
