MICROTIP
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 the third stage of
acoustic amplification. They are used to process small sample volumes ranging from 0.2 -
50 ml.
The MICROTIP is a precision instrument and is designed to give extreme output intensity.
To obtain optimum life from this accessory, the following precautions must be observed:
1. Do not permit the MICROTIP to fall or drop on a hard surface or to bear against the
work table during installation or removal.
2. The MICROTIP should never be operated in air, except to tune the unit. Tuning
should not exceed 10 seconds at the MICROTIP limit (setting 5 on the Amplitude
Control Knob). If tuning cannot be accomplished rapidly, reduce power to about half
of the full output control position and tune again. Then check tuning at the desired
power setting (below setting 5 on the Amplitude Control Knob; the MICROTIP limit).
3. Always immerse the MICROTIP in liquid before turning on the instrument. Immersing
a live MICROTIP 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 in air.
5. The MICROTIP must not be allowed to touch the rim or side of the processing
vessel, especially close to the MICROTIP end (the radiating surface).
WARNING!!
The MICROTIP 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 probe is considerably larger then that of the
standard ½” horn.
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 narrow the probe’s diameter from ½” to ”. 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).
