Developed to meet the needs of analytical chemists, biochemists, and researchers in virtually any field, Sartorious Instruments, based in McGaw Park, Ill., has introduced the world's first toploading microbalance. The M3P Toploading Micro-balance is sensitive to 1 ug (with a maximum capacity of 3 g) and has three sensitivity ranges. The compact balance saves laboratory space and, unlike conventional microbalances, eliminates the need for a large weighing chamber. Since no mechanical devices for extension and retraction of the weighing pan are necessary, the M3P stabilizes quickly (in approximately eight seconds) and can be adjusted to different laboratory stability conditions. The new microbalance requires no door opening or closing, and no lock-down procedures. Listed at $8,925, it allows for rapid sample deposit and retrieval, as well as for quick stabilization.
