2022 New Design Steel Material Acid And Alkali Resistance School Research And Development Lab Fume Cupboard Cost
School Research And Development Lab Fume Cupboard Cost Product Introduction:
A fume hood is a ventilated, enclosed workspace intended to capture, contain and exhaust harmful
or dangerous chemical fumes, vapors and particulate matter generated by procedures conducted
within the hood. No HEPA filtration of either the intake or exhaust air takes place. The air is exhausted
outside the laboratory. This makes a fume hood most suitable for chemical use and other work where
sterility is not a concern. Fume hoods should be utilized for hazardous drug or chemical preparation
and use with waste anesthetic gases such as isoflurane.
A Laminar Flow Hood (LFH), is not a biological safety cabinet. These devices do not provide any protection
to the worker. They are designed to provide a sterile environment to protect the product. Air potentially
contaminated with infectious agents may be blown towards the worker. LFHs should only be used for work
with non-infectious materials such as media preparation. They should never be used with potentially infectious
materials, toxins, volatile chemicals, or materials that may cause hypersensitivity to the worker such as animal

Why do fume hoods use so much energy?
It's the air being sucked through the fume hood, not the fume hood itself that consumes so much energy. For health and
safety reasons, labs use 100% outside air which must be heated or cooled for comfort before it is brought into the lab. In
addition to the energy required to condition the air, a significant amount of additional electricity is required to run large fans
to move the air through the building and through the fume hoods.
How does shutting the sash save energy?
Most fume hoods at Stanford are variable air volume (VAV), meaning that the fume hoods are designed to vary the air flow
based on how wide open the sash height is. Sash position is connected to the building's ventilation system so that a building's
fan speed and the volume of air moved is reduced when the sash is lowered.
Is it safe to shut the sash?
The sash is an important safety barrier between the fume hood interior and the laboratory, protecting the lab user. Sashes should
be opened only to set up or modify an experiment. At all other times, shutting the sash is safest. When the sash is shut there is
still some air flow through the hood to remove any fumes.
How do I remind myself and my roommates to close the sash?
You can post a sticker, like the one shown in the picture below, to remind yourself and your lab mates to close the sash when not in use.
The sticker also educates new fume hood users tha a lower sash is safer, and that the sash should only be open when setting up and
What other fume hood practices can reduce my energy consumption?
• Never use a fume hood just for storing chemicals - they belong in a safety cabinet, which doesn't require huge volumes of air.
• If your fume hood has an occupancy switch, turn it off when not in use.
• If your group is no longer using a specific fume hood, consider having it locked and de-commissioned so air no longer flows through it.
