Ball Pestle Impact Sample
Grinders and Blenders
SpectroMill Ball Pestle Impact Grinders operate on the
principle of propelling one or more ball pestles together
with a sample substance from one end of a SpectroVial
to the opposite end in a rotary "figure-8" path of travel
configuration. The motion is energetic and rapid.
The sample is crushed by the ball pestle and "milled" as the
ball pestle is guided across the concaved interior ends of
the vial to repeat the cycle on the opposite end.
The comminution and blending processes are controlled
by type of sample substance, quantity, time, hardness of the
vial and number of ball pestles.
The SpectroMill incorporates "well-balanced" engineering
that permits high degrees of stability for counter top
operation. A programmable digital electronic timer controls
processing time with a LED and audible alarm indicating

Spectrovial Comminution And Blending Vials
For Spectromill Ball Pestle Impact Grinders
Chemplex offers a wide selection of SpectroVial
comminution and blending vials for use with its
SpectroMill Ball Pestle Impact Grinders. They are
available in a variety of sizes and material substances
to accommodate a wide variety of sample materials. All
SpectroVials are uniquely designed with concaved interior
ends in both the body and cap that are also fabricated from
the same material. Corresponding ball pestles are also
available and offered in compatible materials to the vials.
The importance of concaved interior ends is to ensure that
no sample particles can elude the ball pestle comminution
process by entrapment and caking in the corners similar to
the expected events with the use of traditional "medicine"
The mechanics of the SpectroMills are designed to propel
one or more ball pestles though a "figure-8" path of travel
for impact against the curved interior ends of the vials.
