  • Robust Design

    Grind and polish with the utmost stability thanks to solid steel construction, powder-coated and a working area lined with stainless steel. An integrated spiral rinsing hose with ball valve allows for manual cleaning of the working area. A sedimentation tank on wheels is seamlessly incorporated into the machine base. The Qpol XL utilizes modern and compact machine design.

    Modular Dosing System

    The cleverly integrated dosing system accommodates up to 6 Qdoser Duran glass bottles (1L). These can be further equipped with a magnetic stirrer to ensure optimum distribution of abrasive particles in the suspension. The new level detection for suspensions gives a warning before the container is empty, which is refillable in the ongoing process.

    Optional Cleaning Station

    In the cleaning station, specimens are automatically cleaned with water, ethanol and air or by spin cycling at up to 800 rpm (adjustable).

    Cleaning Boost

    The Cleaning Boost spins residual liquid off the grinding/polishing medium at the end of the preparation process with max. rpm for 3 seconds.

    Convenient Operation

    The modern design of QATM’s proven control software allows for intuitive and user-friendly operation. Standard preparation methods and typical consumables are preinstalled. The Qpol XL comes with a 7" touch screen display, storage for up to 200 programs and User Account Management with variable user rights.
