Currently available grinding pots on the market use metal bolts and nuts to secure the lid, which can lead to the risk of trace amounts of metal powder contaminating important samples due to wear from friction. Additionally, it is quite difficult to remove foreign objects that may enter the bolt holes. The "MC Nylon Pot" replaces the traditional bolt and nut fastening method with a special container design that allows the lid to be easily secured using a handle-type fixture. There is no concern about contamination from impurities caused by wear between metals, and since there are no bolt holes, cleaning is easy. Furthermore, the elimination of the need to attach and detach multiple bolts significantly reduces complicated tasks and working time. 【Features】 ■ The edges of the specially shaped container are secured with a handle-type fixture. ■ Easy to clean. ■ Contributes to a significant reduction in working time. *For more details, please refer to the PDF document or feel free to contact us.
