We fully realize that the SPI "Two-in-One" Easy Duster has applications, not only
in microscopy, but in a wide range of instances where one must keep
electronic equipment or other delicate systems free of dust and/or dust
No matter what the application, the strict adherence to the following
safety cautions are mandatory:
- Never permit the can to be exposed to high temperatures, in order to avoid
the internal pressure exceeding the rated pressure, thereby rupturing the can.
The highest temperature for safe storage is 49° C /120° F. We recommend storage
in a well ventilated area. Exposure to open flame or hot surfaces could cause
the formation of toxic compounds, posing a very real inhalation hazard.
- Never shake or tilt the can when using, keep the can vertical at all times. It is
OK to bend and distort the plastic "straw" to get into a tight space.
Why not to shake or tilt the can.
- When screwing on the screw on vale, always were eye protection!
- We recommend the wearing of safety shoes when using this product. An
accidental dropping of the can on one's toe, if unprotected, can cause serious
injury and a broken toe.
- Do not turn the can up-side-down, other wise liquid refrigerant will come
out, at a very low temperature and which could cause damage to certain plastics
and other materials.
- Avoid contact with eyes, skin, or clothing. And never point the Duster at
anyone and "blow". This could risk very serious injury to another person.
- When using around electrical equipment, turn off all power to the equipment
- Do not puncture or incinerate.
- Use only in well ventilated area because the vapor is heavier than air and
it will displace oxygen available for breathing which could cause the user to
black out. This will not happen from using just a few "puffs", but repeated and
continual use over a short period of time in a space not well ventilated could
pose a safety threat.
For applications in electron and light microscopy:
Examples where the SPI "Two-In-One" Easy Duster can be used:
- Blowing dust off samples before insertion into an SEM or
observation under a light microscope
- Blowing dust off of critical pieces and parts of any TEM or
SEM before being put back together in to the microscope column
- Blowing of dust off of glass slides or coverslips before
applying any kind of a sample
- Blowing dust off of keyboards, mouse balls, and other
critical parts and assemblies to extend useful lifetimes.
- When ever disassembling instrument panels to trouble shoot
PC boards, blow dust off of the critical parts of the
circuit board, sometimes which can cause a shorting out
and failure of the board itself.
The main applications in the dark room are to blow dust off of negatives
prior to exposure either in an enlarger or contact printer. The product is
also useful for keeping dust off of critical parts such as lenses.
Applications around the office:
The SPI "Two-In-One" Easy Duster quickly removes dust and dust accumulations
from photocopy machines, mailing machines, computers and keyboards, mouses, and
most electronic equipment. Tiny bits of paper tend to accumulate in FAX machines,
photocopiers, and a variety of video or other imaging systems.
Applications around the home:
As our homes become more and more electronic, there is a growing number
of items that also can have their useful lifetimes extended by exercising a
realistic preventative maintenance program, which includes keeping dust and
dust accumulations out of such electronic devices.
When a cabinet is opened up, generally speaking, the PC boards are covered
with a certain amount of dust. The SPI "Two-In-One" Easy Duster is the ideal way
to "blast off" this dust and dust accumulation, without causing any damage to the
components on the board. Again we want to caution that for this application be
absolutely certain that the power is turned off to the electronic device.
If there is an "intermittent" kind of a failure problem, and if a suitable
"extender board" is available, then the can can be used in the inverted position,
so that liquid refrigerant can be expelled, and each component, one by one, can be
chilled and then the performance of the system observed. Eventually this way, it is
often times easy to find the "problem" component that is producing the intermittent
