Blending Vials for Spectromill® Ball Pestle Impact Grinders

There is a wide selection of SpectroVial® blending vials for use with SpectroMill Ball Pestle Impact Grinders. Available in various sizes and materials to accommodate a variety of sample materials. All SpectroVials® are designed with concave interior ends in the body and cap that are fabricated from the same material. Corresponding ball pestles are available in compatible materials to the vials.

The SpectroMills® is 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.

Polystyrene SpectroVials®

Clear, hard and rigid. Thick walled and reinforced ribbed exterior ends. Designed to withstand repeated ball pestle impact. Friction fitting caps have tabs that facilitate assembly and disassembly. Ideal for blending applications and suitable for comminuting soft sample materials.

Stainless Steel SpectroVials®

General purpose comminuting and blending moderately hard samples applications. Threaded caps have concaved interior ends.

Rust Resistant Stainless Steel SlipFit® SpectroVials®

SlipFit SpectroVials are used for general purpose comminuting and blending moderately hard samples. They also have the added convenience of easily slipping the caps onto the vial bodies. They are fabricated from a rust-resistant stainless steel for cleansing with water. Interior ends of both caps and vial bodies are concaved.

Ball Pestles for SpectroVials®

Ball pestles serve as the grinding media in SpectroVials® for comminuting powdered material substances in SpectroMill Ball Pestle Impact Grinders. The selection of a ball pestle material is a function of the type of SpectroVial in use.

Stainless steel metallic ball pestles are primarily used for comminuting relatively hard sample substances. Tungsten carbide ball pestles in combination with titanium carbide SpectroVials are much more effective grinding media for extremely hard samples.

Plastic ball pestles are intended for use with plastic polystyrene SpectroVials. Plastic is relatively soft and not very effective in the comminution process. Its principal application is for blending sample substances or for soft samples.
