实验室工厂，或实验室磨坊磨床，利用机械力将非共生的批量样品粉碎成较小的，代表性的，同质的样品进行分析和质量控制测试。磨坊由磨碎元件组成，例如搅拌器或切割刀片，该材料安装在不锈钢或一次性塑料铣床中。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?
实验室研磨厂旨在适应具有不同物理特性的样品的各种磨削元素：干燥，弹性，湿，硬，脆性和纤维状。
Impact mills最适合磨削硬，脆性或干燥的饲料材料，例如谷物，大麦，纤维素，药物，树脂和种子。
切割工厂最适合研磨弹性，纤维和软饲料材料，例如香料，啤酒花，纸，塑料和根。颌骨破碎机利用固定和可移动的下颌进行高压压碎玻璃和煤。
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

样品材料的粒度或晶粒直径控制适当的实验室磨坊的选择。
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)
每分钟旋转（RPM）表示的最大研磨速度定义了每个工厂的最佳样本类型。
IKA’s MF10型号的速度范围为3,000至6,500 rpm，专为药房样品（如维生素，片剂和根部）以及橡胶和塑料设计。
IKA M20型号s maintain a fixed speed of 20,000 rpm for pulverizing grain, seeds, ceramics, salt and active carbon.
IKA管磨坊速度范围为5,000至25,000 rpm，碎茎，叶子，烟草，生姜，花，药胶囊和酶粉末。
IKA A11型号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-实验室磨机
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 millsand grinders include low-power models with 80-Watt 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 -GMP符合性实验室磨坊
IKA M20磨机包括可移动，易于清洁的，钢制研磨室和USB接口，用于安全数据导出。
G3 -封闭机磨室
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.
