MICROTIP
TM
Part Numbers: (418, 419, 419A, 419B)
MICROTIPS
TM
attach directly to the end of the ½” diameter tapped horn in place of the flat tip. The
MICROTIP
TM
Probes are tapered down to a narrow point and serve as a third stage of acoustic
amplification. They are used to process small sample volumes ranging from 0.2 - 50 ml.
The
MICROTIP
TM
is a precision instrument and is designed to give extreme output intensity. To
obtain the maximum life from this accessory, the following precautions must be observed.
1. Do not permit the MICROTIP
TM
to fall or drop on a hard surface or to bear against the
worktable during installation or removal.
2. The MICROTIP
TM
should never be operated in air.
3. Always immerse the MICROTIP
TM
in the sample liquid before turning on the instrument.
Immersing an energized MICROTIP
TM
into the sample may cause splashing,
aerosoling or foaming.
4. If the material being treated aerosols or foams, the generator should be turned off
immediately as this is equivalent to operating the
MICROTIP
TM
in air and will cause it to
heat up and possibly fail.
5. The MICROTIP
TM
must not be allowed to touch the rim or side of the processing vessel,
especially close to the MICROTIP
TM
end (the radiating surface).
WARNING!!
The MICROTIP
TM
operates close to the stress limits of titanium and any of the above
mentioned conditions can introduce a microscopic crack in the tip or cause it to break. The
output intensity (or amplitude) of the MICROTIP
TM
probe is considerably larger than that of the
standard ½” horn. All cautions and warnings must be observed at all times.
STEPPED MICROTIP
TM
Part Number: (420)
The stepped MICROTIP
TM
consists of an upper section and a lower section. The upper section is
used in place of the standard horn, and the lower section attaches directly into the upper section. The
lower section has 3 steps that reduce the probes diameter from ½” to 1/8”. The Stepped
MICROTIP
TM
is used in place of a tapered MICROTIP
TM
when a longer reach and narrower profile are
required, such as when processing samples in long, narrow test tubes (e.g. 12mm x 75mm).
