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 SpectroVial® grinding and blending vials 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" vials.
The mechanics of the SpectroMill® Ball Pestle Impact Grinders 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. The spherical shape of the balls is responsible for sample "mulling" against the curvature of the interior vial ends.
The combination of ball pestle impacts and mulling actions effectively comminute the sample substance for uniformity of particle size, configuration and distribution producing a thoroughly homogeneous mixture.
