SpectroVial® Ball Pestles for Grinding and Blending Samples

SpectroMill® Ball Pestle Impact Grinders/Mixer

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.

Homogeneous powder blending

Uniform particle size reduction

Small compact bench-top size

Accommodates 2 to 30cm3 sample

Touchscreen user interface

Programmable count-down timer

Programmable methods for storage and recall

Audible cycle compeltion alarm

The SpectroMill® Ball Pestle Impact Grinder/Mixer is a compact bench-top device used for blending and pulverizing samples ranging from 2 to 30cm3. A combination of features provides the analyst with a virtually unlimited capability to process innumerable types of samples. Typical samples include: geological rocks, minerals, dried soil and sand, cement, sinters, slags, ceramics, catalysts, glass, pharmaceuticals, dried plant and animal tissues, seeds and many other types of samples requiring fine particle size, uniform configuration, homogeneous distribution and reproducible x-ray data. It is engineered to rapidly propel one or more ball pestles together with a sample substance to strike the interior contoured ends of a sealed SpectroVial® container. The mechanics of the system are designed to guide a ball pestle and sample through a “figure-8” path of travel within the grinding/mixing vial prior to impact against the contoured vial and cap ends. 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®-TS Touchscreen Ball Pestle Impact Grinder/Mixer includes a touch-screen that offers the convenience and capability of operating and recalling user-assigned programmed methods. This feature unique to the SpectroMill-TS eliminates re-establishing grinding and mixing parameters for different types of samples.

Multi Sample Simultaneous Processing SpectroMill® Ball Pestle Impact Grinders are engineered with a SpectroVial® clamping mechanism that will accommodate and process up to five different samples simultaneously to the same pre-programmed time. This is achieved with optionally available Multi SpectroVial® Adaptors that contain cavities of appropriate size to accept Chemplex® clear plastic polystyrene, annealed stainless steel, rust resistant stainless steel and titanium carbide SpectroVial® grinding/mixing vials.
