什么是实验室分散器？它与均质器有何不同？
实验室分散器, sometimes referred to as high-speed shearers or rotor-stator mixers, are a type of overhead stirrer designed to disperse, rather than mix, compounds. As opposed to homogenizers, which uniformly mix two or more miscible components, dispersers create a mixture of two or more immiscible components owing to liquid-liquid or solid-liquid phase separations. Popular dispersions include emulsions (liquid particles dispersed into another liquid) or grind dispersions (solid particles dispersed into a liquid).
What are Lab Dispersers Used For?
实验室分散器are used in the biotechnology industry to form liquid biomolecular condensates, the food industry to produce vinaigrettes or homogenized milk, the pharmaceutical industry to create creams, ointments and salves, and the chemical industry to manufacture polymers, such as rubber or latex.
分散器are composed of a high-speed, spinning rotor connected to a stationary stator tube, regulated by an analog or digital controller. Interchangeable dispersing elements, such as cutting heads, propellers, dissolvers and saw tooth grinders, are installed onto the stator tube for different shearing applications. Although small-scale dispersers may be operated by hand, most models are mounted to a telescoping base stand for stability.

A1 - Batch Lab Dispersers
实验室批处理分散剂设计用于连续混合散装样品（量高达30升），例如油漆配方，胶粘剂，陶瓷和油。随着样品粘度在分散过程中的变化，批处理模型旨在保持混合速度。由于批处理处理可能会使乳液暴露于机载污染物中，因此批处理分散剂不适用于无菌样品。

A2 - Inline Lab Dispersers
Inline lab dispersersare designed for sterile, air-free, pressurized suspension, emulsification, and deagglomeration of inline fluid samples, such as pharmaceutical filling lines. Inline dispersers process smaller volumes than batch dispersers, but reach high speeds than most high-volume models.
C - Lab Disperser Maximum Volume
（返回图表）
Low-throughput batch dispersers and inline dispersers are designed to process samples between 26 ml and 2 liters in volume. High-throughput batch dispersers accommodate samples up to 50 liters in volume.
E - Speed Control

E1: Stepless Lab Disperser
毫无根据lab dispersers的fer a full range of speed controls including small rpm increments for operations calling for specific mixing speeds.
E2：固定实验室分散器
Fixed lab dispersersdo not include speed range controls. These models are optimal for recurring mixing operations specifying one mixing speed.
F - Lab Disperser Controllers

F1: Analog Lab Dispersers
模拟lab dispersers controllersinclude a speed dial and power switch. Economic alternative to digital models, these units do not include on-board software with timers and data export capabilities.
F2: Digital Lab Dispersers
数字实验室分散器控制器include a speed dial with LED readout of current mixing speed. Certain digital models, likeIKA的Ultra-Turrax T 65disperser, include red emergency stop buttons for immediate shutdown.
