Introduction
For laboratory and pharmaceutical purposes, a
laminar flow hood is a kind of air-filtering
device that offers a sterile working
environment. A laminar flow hood's main job is
to keep samples and tools clean while performing
procedures that call for a sterile environment.
We will go through the operation, varieties,
uses, and upkeep of a laminar flow hood in this
presentation.

Working theory
The filtered air is then supplied to the
workplace in a laminar or unidirectional flow
after passing via several ducts. This indicates
that the air flows normally from the top of the
hood down to the work surface in a straight line
with a steady velocity and direction. The
samples and equipment are kept clean by this
flow, which guarantees that any particles or
germs created by the job are moved far from the
operator and the workstation.
The idea of a laminar flow hood is to provide a
clean, even airflow over a work area. HEPA
(High-Efficiency Particulate Air) filters,
which eliminate any airborne impurities bigger
than 0.3 microns, are used to pull air into the
hood.

Laminar flow hood varieties

• Vertical and horizontal laminar flow hoods are
  the two basic varieties. The type of hood to use
  will depend on the application and the type of
  work being done.
• Hood with the vertical laminar flow A hood with
  a vertical laminar flow is made to create an
  airflow that is laminar downward. In scientific
  and medical applications including tissue
  culture, cell culture, and microbiology, this
  kind of hood is frequently utilized. The
  workplace is reached by a front aperture, and
  the operator works while standing outside the
  hood.
• Hood with a horizontal laminar flow A hood with
  a horizontal laminar flow is made to allow air
  to flow laminarly from the rear to the front.
• Electronics, optical, and semiconductor
  manufacturing sectors frequently employ this
  kind of hood. Inside the hood, the operator
  occupies a sitting posture, and a side aperture
  provides access to the workplace.

Conclusion
In many laboratory and pharmaceutical
applications, a laminar flow hood is a crucial
instrument for ensuring a sterile work
environment. They come in two primary varieties
vertical and horizontal, both of which work on
the premise of distributing a consistent and
sterile airflow throughout a workstation. To
guarantee the hood's efficiency and avoid
contaminating samples or equipment, proper
upkeep, and testing are required.
