What is the hood?

The

hood is a piece of laboratory equipment used to protect scientists from the possible negative effects of the experiment. This is mainly done by maintaining air inside the hood of smoke from people who make an experiment. The hoods also offer additional features and protection that are useful in the laboratory environment. The base of the smoke hood usually looks like a typical laboratory bench and can have a storage over the floor. At the top and connected to the bench is a very large cover called the cabinet. The cabinet will have a movable door or wing on the front that can be lifted or reduced to provide access to the worktop. Options around the edges of the worktop and/or at the top of the cabinet allow gas to be removed in the cabinet. Experiments are carried out inside the wing with the wing as low as possible to protect the experimenters.

The hoods come in two main types: recirculation and dukt. The recirculation bonnet of the smoke attracts air from around the experiment to the built -in fiLtra and then release the cleaned air back to the laboratory or cabinet. The fan built into the cabinet is usually a primary pull in the recirculation hood. The hooded hood of smoke has air waste from it and to the ventilation system where it is cleaned and then released outside the building. More hooded with smoke is usually connected to such a venting system.

Smoke hoods provide protection against more than dangerous gases. The closed nature of the cabinet helps to protect the experimenters from injury fragments if something explodes or spray. The species hood is also usually made of materials for taking flame, so unexpected fires tend to be as harmful as they were in the open space.

Most hoods from smoke have a lot of functions to be built into experimenting. The lighting lights allow experimenters to see what they do. Electrical sockets inside and outside the hood of smoke are common and allow electronic devices to be easily used during the experiment. VacuumThe pumps are also common and allow low -pressure or vacuum experiments. Gas outlets, which can be associated with different tanks and flows, are useful for specific experiments, as well as water faucets and drains.

Alternative to the smoke hood is a device called hands. These long devices similar to tubes, also known as the vacuum of snorkels, can be placed in experiments in an open laboratory environment to remove any dangerous gases. There are usually more arms in the laboratory that are equipped with them and are almost always connected to the central ventilation system or air cleaner. Rumen arms are much more mobile and compact than the hood, and also cost significantly less. They have many uses, but most often are academic laboratories, where many experiments are performed at a time on long laboratory benches.
