IOM Stainless Steel Casse e
Use stainless steel casse e only.
Autoclave stainless steel casse e up to 392 F (200 C).
Reminder: Use powder-free gloves and forceps to insert the fi lter and foam into the
casse e (see Filter Casse e: Opening, Installing Filter, and Closing). Users may wish to
use sterile gloves and forceps depending on the contaminant of interest.
Storage Requirements for IOM MultiDust Foam Discs
IOM MultiDust Foam Discs are sensitive to heat, humidity, and ultraviolet light.
The foams must be stored in the supplied packaging (including the resealable bag).
Keep in a cool, dry place away from direct sunlight. SKC recommends checking the
condition of the foams before use. Note that the expiration date on the package is
subject to correct storage as detailed above.
General Weighing Guidelines
• The plastic casse e with fi lter and MultiDust Foam Disc (if used) should be
equilibrated overnight in a balance room under controlled humidity conditions
and weighed. Maintain a stable humidity level in the balance room. A stainless
steel casse e with fi lter may be desiccated.
• Before pre and post-weighing, wipe the external surface of the sampler with a
clean lint-free paper, cloth, or so brush.
• For inhalable only, pre and post-weigh casse e with fi lter as a single unit. For
inhalable and respirable, pre and post-weigh fi lter, foam, and casse e together
fi rst for inhalable result and then fi lter and casse e bo om together for respirable
result.
• Field blanks can be used to correct weights when using plastic casse es at low
fi lter loadings. See Sample Blanks on page 9.
• The IOM casse e assembled with fi lter or the fi lter alone should be weighed
on a fi ve-fi gure forced balance. Allow the casse e three-and-a-half minutes to
stabilize before taking a reading. The same balance should be used for both pre
and post-weighing procedures.
