• ALWAYS test the MicroSprayer® Aerosolizer with water after cleaning it and before
storing it to observe that it continues to deliver a full, uniform plume of spray that is as good as
its operation when new.
• ALWAYS blow air through the MicroSprayer® Aerosolizer fully before storing to
eliminate remaining liquid inside. Direct a small stream of compressed air into the threaded
sprayer hub of the MicroSprayer® Aerosolizer until all fluid remaining in the sprayer tip is
expelled. Products such as “DUST-OFF” or similar for cleaning computer keyboards are also
suitable. Do not blow compressed air through the device without testing it first with water. If it is
partly clogged, drying it with air will may further harden any material in the tip.
• ALWAYS clean the protective plastic end cap that came with the MicroSprayer® Aerosolizer
and screw it back on before storing it to remove any dust or grit that has gotten on it Always store
the MicroSprayer® Aerosolizer and FMJ-250 Syringe in the original boxes in which they were
shipped to prevent it from getting dropped or bent.
What to do if MicroSprayer® Aerosolizer becomes blocked or clogged
If the sprayer tip starts to clog, you will notice an increase in the force required to depress the
syringe plunger. In general, it does not help at this point to increase the force on the plunger as this
may only serve to further drive the offending material into the small passages of the sprayer tip. If this
occurs:
1. Place the assembled sprayer tip in very hot dionized or distilled or filtered water, or soak in
organic solvent and draw back on the syringe plunger, holding it in the fully retracted position
for 15 seconds. Then unscrew the MicroSprayer® Aerosolizer from the FMJ-250 Syringe, eject
the contents of the syringe and flush it thoroughly with water. Repeat.
2. Ultrasound combined with an organic solvent, or an enzymatic cleaner such as Enzol® may also
help break apart clogged particulates in the tip.
3. If that doesn’t work, and the MicroSprayer® Aerosolizer is completely blocked and is not letting
any liquid pass through at all, contact Penn-Century, Inc. for additional recommendations.
Care of the FMJ-250 High Pressure Syringe
The FMJ-250 High-Pressure Syringe is made of stainless steel outer layer with a borosilicate
glass liner, a PCTFE seal and other chemically resistant components, and designed to be sterilized and
re-used.
NOTE: The FMJ-250 High Pressure Syringe is very durable and will withstand normal use.
Inside the borosilicate glass liner (bore) inside the syringe that can crack, however, if the
syringe is subjected to temperatures higher than standard autoclave temperatures, or to
sudden temperature contrasts, or is dropped on the floor or forcefully strikes a hard
surface. If so, the syringe may leak or the plunger may no longer move smoothly up and down in the
glass bore of the syringe. If the glass liner is cracked, the syringe will not function properly and the
device will not be repairable.
Cleaning methods:
· The syringe can be sterilized to with standard materials. Sterilization with standard cold
liquids is usually sufficient. The following are also safe for cleaning and disinfecting the device:
Cidex®, Cidex Plus®, Cidex OPA®, Enzol® Solutions
