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.
