This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Allied High Tech MetPrep 4 is a microprocessor-controlled grinding/polishing machine for semiautomatic sample preparation. The MetPrep 4 is programmable for up to 25 steps, including platen speed, comp/contra rotation, cycle time, fluid selection, sample force, sample rotation speed, platen rinse and force reduction. The MetPrep 4 is designed and manufactured by Allied in the USA and carries a two-year warranty.[1][2]
What it is
How it works
The MetPrep 4 uses a rotating platen and a pneumatically or electrically actuated power head that holds sample mounts. The power head applies controlled force to the samples against the abrasive surface. The microprocessor-based controller allows programming of up to 25 steps, including parameters for platen speed, rotation direction, cycle time, fluid selection, sample force, sample rotation speed, water rinse, and force reduction.[1]
The system supports either central force mode, where multiple samples are pressed together on a common plane, or individual force mode, where each sample receives independent force. The power head tilts up to allow unhindered access to the platen and sample holder. The platen can be aluminum or magnetic, and the machine includes an electronic coolant control with adjustable flow, a bowl flush to remove debris, and an emergency shut-off switch.[1]
The MetPrep 4 uses a three-phase AC motor with single-phase input and a reduction gearbox for constant high-torque output. For 115 volt models, platen speed ranges from 50 to 400 RPM in 10 RPM increments; for 230 volt models, the range is 40 to 600 RPM. Jog speed has the same ranges. The platen diameters available are 10 inches (250 mm) or 12 inches (300 mm).[1]
