实验室厂或者实验室磨机，利用机械力来粉碎非均匀，分批样品进入更小，代表性的均匀样品，用于分析和质量控制测试。铣刀由研磨元件组成，例如挡板或切割刀片，容纳在不锈钢或一次性塑料铣削室内。研磨元件连接到由计时器或数字控制器调节的高速电动机。
What are Laboratory Mills Used For?
实验室磨床设计用于适应具有不同物理性质的样品的各种研磨元件：干燥，弹性，湿，硬，脆性和纤维状。
Impact mills用于研磨硬，脆或干燥的饲料材料，例如谷粒，大麦，纤维素，药物，树脂和种子。
切割厂磨削弹性，纤维和软饲料材料，如香料，啤酒花，纸张，塑料和根。颚式破碎机利用固定和可动钳口，用于高压碎玻璃和煤。
Analytical mills are commonly used for impact grinding of frozen food and vegetation.
Mortar grinders are used to pulverize dry or suspended organic samples, like homogenized pastes or creams.
Bead mills are optimal for shearing cell and tissue culture sample preparations.
a - 实验室磨坊饲料样品硬度
(back to chart)
The Mohs Hardness Scale charts the relative hardness, or scratch resistance, of various materials from 1 (softest) to 10 (hardest). The hardness test is typically performed by pressing a loaded indenter object onto the surface of the test material to measure the size of the lasting impression. Examples of 5-Mohs materials include bone, iron, enamel, glass and titanium. Common 6-Mohs materials include steel, silica, porcelain, and zirconium.
B - Feed Grain Sample Diameter

样品材料的粒径或粒径，控制适当的实验室磨机的选择。
IKA’s M20 modelspecializes in pulverizing small-particle samplesup to 7mmin diameter whileIKA’s MF10 systemaccommodates large-particle samplesup to 10mm在直径上。
C - Maximum Laboratory Mill Speed
(back to chart)
每分钟转速（rpm）的最大磨削速度定义每个磨机的最佳样品类型。
IKA’s MF10型号的速度范围为3,000至6,500 rpm，专为药房样本而设计，如维生素，片剂和根，以及橡胶和塑料。
IKA M20型号s maintain a fixed speed of 20,000 rpm for pulverizing grain, seeds, ceramics, salt and active carbon.
Ika管米尔斯速度范围为5,000至25,000 rpm，粉碎茎，叶子，烟草，姜，花，药物胶囊和酶粉。
IKA A11模型have a fixed speed of 28,000 rpm to grind cellulose, resin, animal feed, spices, coal and detergents.
D - Laboratory Mill Cooling Method
(back to chart)
Effective sample preparation prior to milling ensures maximal grinding efficiency and mitigates instrument wear-and-tear. Elastic or fibrous samples, such as rubber and plant materials, are frozen over dry ice prior to grinding. Biological samples, such as nucleic acids and proteins, are cryogenically frozen in liquid nitrogen before milling. To prevent damage to the unit, wet samples are passively cooled and dried before milling to prevent adhesion to grinding elements.
E - 实验室轧机体积
Low-throughput models are designed to accommodate sample volumes down to 40 ml while high-throughput models process samples up to 250 ml in volume.
F - Laboratory Mill Motor Output
(back to chart)
IKA’s portfolio of laboratory mills并与80瓦磨床包括低功耗模型motors and high-power models with 500-Watt motors. IKA’s standard units include protection mechanisms such as emergency-stop switches, overheating alarms, and grinding enclosures to prevent operator exposure.
G - 特殊实验室研磨功能
(back to chart)
G1 - Lab Mills with Adjustable Speed Controls
Certain models include rotary dials to adjust current mixing speed, target mixing speed, and mixing time.
Ika管磨机控制includes a touch-screen keypad and LED display of real-time mixing conditions.
G2 - 符合GMP标准的实验室磨坊
IKA M20轧机包括可拆卸，易于清洁，钢磨床和USB接口，可安全数据导出。
G3 - Enclosed Mill Grinding Chamber
Ika管磨机控制includes an enclosed, plastic grinding chamber for sample and operator protection. The disposable grinding chamber can be removed and used for long-term sample storage.
