UNIPOL-300 Mini Automatic Grinder/Polisher with 3″ Lapping Plate and Adjustable Pressure for TEM and Metallographic Sample Preparation
The UNIPOL-300 is engineered to facilitate the preparation of transmission electron microscopy (TEM) and metallographic samples within a single mounting setup. It is particularly suited for laboratories requiring precise polishing of small specimens, typically less than 25 mm in diameter and 20 mm in height. This compact automatic grinder/polisher simulates manual polishing by moving the sample holder randomly over a fixed 3″ glass lapping plate, ensuring uniform surface finishing without operator intervention.
The device supports variable sample holder speeds and adjustable pressure loads ranging from 0 to 5 Newtons, controlled by an internal spring mechanism. An automatic timer allows operation from zero up to 99 hours, enabling unattended polishing cycles. The UNIPOL-300 operates on switchable AC power supplies (110V and 208-240V, 50/60Hz), making it suitable for global use.

대표적인 적용 분야
The UNIPOL-300 is ideal for preparing small diameter specimens for transmission electron microscopy, metallographic analysis, failure analysis, and medical testing. It is well suited for low volume laboratories and research facilities requiring precise surface preparation of samples under 25 mm diameter.
구성 및 작동 안내
The standard package includes two 1″ diameter sample holders (one for flat samples and one for bulk samples), one rubber polishing collar, one 3″ glass lapping plate, three 3″ poromeric polishing pads for final polishing, a set of three diamond paste syringes (0.25, 1.0, and 3.0 micron grit), an AC power cord, and an operation manual. Additional rubber collars and glass lapping plates are available as optional accessories.
Users should ensure samples are securely mounted and compatible with the sample holders. The adjustable pressure and variable speed settings allow optimization for different materials and polishing requirements. The unit is CE certified; however, NRTL certification is not currently available.
