Specification BatteriesIncluded : 1 BatteriesRequired : 1 Brand : Huanyu BulletPoint : Tube Rack, 25 x 2ml Tubes, 2 per pack BulletPoint1 : Highly polished, smooth, easy to clean, low abrasion to the equipment BulletPoint2 : High mechanical strength, good toughness, impact resistance, no broken beads BulletPoint3 : 304 stainless steel balls are mostly used for the treatment of hard samples, which can be used for pulverization, homogenization and refinement. BulletPoint4 : They are widely used in the fields of metal, ore, ceramics, pigments and electronics. BulletPoint5 : In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen.
