Completing the Test
For an initial test run: When no more material can be seen falling
through the sieves, note time elapsed. This value should be used for
subsequent testing of the same material to assure repeatable results.
For a routine test run: When the timer counts down to "0", open
the door and follow the procedures listed for 'Removing the Stack
Assembly'.

collector.
The parts can be weighed directly on the weighing device, removing
the need to transfer the powder to a weighing dish (thus reducing
potential sample loss).
well.
weights. Subtracting the tare weight from the post-test weight yields
the mass of the sample retained on the part. The percentage retained
at each sieve size can be calculated simply by comparing the weight
on each part with the starting sample weight.
CARE OF ADVANTECH MODEL L3P SONIC SIFTER SEPARATOR
AND ACCESSORIES
The Advantech Model L3P Sonic Sifter Separator and Accessories will perform
satisfactorily for many years if the following basic care instructions are observed:
Cleaning the Sieves and Stack Assembly Parts
For best results, stack assembly components and sieves should be
cleaned in an ultrasonic cleaner of 150 watts or less. General cleaning
is best accomplished in a mild solution of dishwashing detergent and
water maintained at 75-80°F (24-27° Celsius). Ultrasonic cleaning has
proven to be the most effective method of removing particles plugging
woven wire cloth sieve openings. Regular ultrasonic cleaning will help
prevent particle buildup in the sieve openings, thus reducing the
amount of time each sieve must be exposed to ultrasonic vibrations.
Care must be taken in how long the sieves are exposed to the
ultrasonic vibrations, as damage can result from overexposure.
NOT ultrasonically clean precision sieves.
After washing, rinse the parts with tap water, and allow to air dry. DO
NOT expose the sieves, spacers, or top cone to heat sources of any
kind.
