SPEX SamplePrep provides products for grinding and pulverizing even the toughest samples. These include high-energy ball mills, swing mills, and cryogenic mills. Over the past few decades, the SPEX SamplePrep Mixer/Mill®, widely known as the “SPEX Mill”, has become the industry standard for mechanical alloying applications. The high energy of the milling action, and the durability of the motor, allow running for extended periods. We’re also known for our Freezer/Mill®, the only “True Cryogenic Mill” uses liquid nitrogen to pulverize samples regarded as impossible to grind. Our 2000 Geno/Grinder®, is a high-throughput tissue lyser and also used for RNA/DNA extractions.
