Description: SPEX SamplePrep 8000M Mixer/Mill "The Spex Mill"
8000M Mixer/Mill® High-Energy Ball Mill, Shaker Mill
S/N: 08015
Operating Manual Included
Includes Stainless Steel Vial, P/N: 8007
   Vial size 2 1/4 in. diameter x 3 in. Vial body and cap liner made of hardened 440C stainless steel.
   Vial includes screw-on cap with O-ring to permit wet or dry grinding/mixing. Grinding load 3-10 ml;
   mixing load approx. 25 ml.

The SPEX SamplePrep 8000-series Mixer/Mills are efficient, compact laboratory mills capable of pulverizing samples in the 10-gram range. Functionally described as shaker mills or high-energy ball mills, these Mixer/Mills shake containers back and forth approximately 1080 cycles per minute (60 Hz model). These multi-purpose mills are capable of reducing hard, brittle samples to analytical fineness, blending powders, making emulsions, and performing mechanical alloying.

The vial, which contains a sample and one or more balls, is shaken in a complex motion that combines back-and-forth swings with short lateral movements, each end of the vial describing a figure-8. The length of that swing is the same as the internal length of a standard 8000 series vial, about two inches. With each swing the balls impact against one end of the vial, simultaneously milling the sample to a powder and blending it. Because of the amplitude and velocity of the clamp’s swing, each ball develops fairly high G-forces, enough to pulverize the toughest rocks, slags and ceramics.

The single-clamp 8000M Mixer/Mill, known simply as “the Spex Mill” to thousands of users, has served spectroscopists and analytical chemists for over forty years. The clamp mechanism has changed little since the earliest versions, simply because it has proven extremely durable. Many of the earliest 8000 Mixer/Mills are still in service. An electronic 100-minute timer has replaced the original wind-up timer and the mill’s safety features have been improved: the lid is now locked down until the clamp stops moving.

8000-series Mixer/Mills have been used for pulverizing rocks, minerals, sand, cement, slag, ceramics, catalyst supports, and hundreds of other brittle, often hard samples. Early in its market introduction, the 8000 was used to grind samples, then blend them with graphite for arc/spark spectroscopy; now similar samples are ground, then blended with binder before being pressed into sample discs for XRF. The vigorous motion of the clamp is also excellent for making emulsions, such as paints, inks and pharmaceuticals. 8000M Mixer/Mills have also achieved notoriety for their ability to mechanically alloy small quantities of materials in fields such as superconductor research.
