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 accumulations.

No matter what the application, the strict adherence to the following safety cautions are mandatory:

For applications in electron and light microscopy:

Examples where the SPI "Two-In-One" Easy Duster can be used:


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.

Electronics trouble-shooting:

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 failure.
