{"product_id":"mbag","title":"Agate Milling Balls (2-20 mm), 100-300 pcs\/bag, MBAG","description":"\u003cp\u003eAgate Milling Balls—carved and precision-polished from high-purity, naturally occurring microcrystalline silica (SiO2, predominantly chalcone\/quartz bands)—represent a traditional laboratory favorite for lower-energy, high-purity sample preparation. Unlike technical ceramics synthesized from artificial chemical powders (like Alumina or Zirconia), high-grade laboratory agate is selected directly from natural mineral deposits. It is thoroughly processed to eliminate cracks, producing a highly dense, glass-smooth grinding media.\u003c\/p\u003e\n\u003cp\u003eThe critical advantages of agate milling balls are: (1) \u003cstrong\u003eZero Heavy Metal Contamination\u003c\/strong\u003e: Because agate consists purely of silicon and oxygen lattice frameworks (SiO2), it completely eliminates the introduction of structural transition metals such as Iron (Fe), Chromium (Cr), Nickel (Ni), or Cobalt (Co) into your formulation. This makes it an invaluable baseline standard for environmental soil assaying and biochemical sampling. (2) \u003cstrong\u003eHigh Resistance to Acids and Solvents\u003c\/strong\u003e: Agate possesses exceptional chemical stability. It is completely inert when exposed to organic solvents (ethanol, acetone, toluene) and resists attack from strong mineral acids (like hydrochloric acid, HCl, or nitric acid, HNO3). Exception: Never expose agate to hydrofluoric acid (HF), which aggressively dissolves silica frameworks. (3) \u003cstrong\u003eGentle Mechanical Attrition\u003c\/strong\u003e: Because of its lower density (2.65 g\/cm3), agate balls do not slam into sample matrices with the destructive kinetic force of tungsten carbide or heavy steels. Instead, it relies heavily on high-surface-area friction and gentle rolling attrition. This makes it ideal for processing fragile crystals or organic components that would structurally degrade or deform under intense thermal\/impact stress.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 260.775px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMBAG\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eBall Material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAgate\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eMilling Ball Sizes\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e2-20 mm (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eother sizes can be supplied upon request\u003c\/span\u003e)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eSpherical Resolution\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e±5 um\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 22.775px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 22.775px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 22.775px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e100-300 pcs\/bag (depends on the ball sizes)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"MQKJ","offers":[{"title":"2 mm \u0026 300 pcs","offer_id":47974831587558,"sku":"MBAGD2P300","price":69.0,"currency_code":"USD","in_stock":true},{"title":"3 mm \u0026 300 pcs","offer_id":47974831620326,"sku":"MBAGD3P300","price":79.0,"currency_code":"USD","in_stock":true},{"title":"4 mm \u0026 300 pcs","offer_id":47974831653094,"sku":"MBAGD4P300","price":79.0,"currency_code":"USD","in_stock":true},{"title":"5 mm \u0026 300 pcs","offer_id":47974909313254,"sku":"MBAGD5P300","price":89.0,"currency_code":"USD","in_stock":true},{"title":"6 mm \u0026 300 pcs","offer_id":47974909346022,"sku":"MBAGD6P300","price":89.0,"currency_code":"USD","in_stock":true},{"title":"8 mm \u0026 200 pcs","offer_id":47974909378790,"sku":"MBAGD8P200","price":99.0,"currency_code":"USD","in_stock":true},{"title":"10 mm \u0026 200 pcs","offer_id":47974909411558,"sku":"MBAGD10P200","price":109.0,"currency_code":"USD","in_stock":true},{"title":"12 mm \u0026 200 pcs","offer_id":47974909444326,"sku":"MBAGD12P200","price":119.0,"currency_code":"USD","in_stock":true},{"title":"14 mm \u0026 100 pcs","offer_id":47974909477094,"sku":"MBAGD14P100","price":99.0,"currency_code":"USD","in_stock":true},{"title":"16 mm \u0026 100 pcs","offer_id":47974909509862,"sku":"MBAGD16P100","price":109.0,"currency_code":"USD","in_stock":true},{"title":"18 mm \u0026 100 pcs","offer_id":47974909542630,"sku":"MBAGD18P100","price":139.0,"currency_code":"USD","in_stock":true},{"title":"20 mm \u0026 100 pcs","offer_id":47974909575398,"sku":"MBAGD20P100","price":159.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/MBAG_main.jpg?v=1783916290","url":"https:\/\/echemsupplies.com\/products\/mbag","provider":"EChem Supplies","version":"1.0","type":"link"}
