What is a Lab Disperser? How is it Different from a Homogenizer?
Laboratory dispersers, 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?
Laboratory dispersers 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.
分散器由高速的旋转转子组成，该转子连接到固定的定子管，由模拟或数字控制器调节。可互换的分散元素，例如切割头，螺旋桨，溶解器和锯齿磨碎器，都安装在定子管上，以用于不同的剪切应用。尽管可以手工操作小型分散剂，但大多数型号都安装在望远镜基础架上以稳定。

A1 - Batch Lab Dispersers
Laboratory batch dispersers are designed for continuous mixing of bulk samples (up to 30 liters in volume), such as paint formulations, adhesives, ceramics, and oils. As sample viscosities change during the dispersion process, batch models are designed to maintain mixing speeds. Since batch processing may expose the emulsion to airborne contaminants, batch dispersers are not appropriate for sterile samples.
A2-内联实验室分散器
内联实验室分散器专为无菌，无空气，加压悬浮液，乳化和内联液样品（例如药物填充管线）的脱离。内线分散器处理的数量比批处理分散剂较小，但要比大多数大批量模型达到高速。

Low-speed lab dispersers maintain mixing speeds of 6,000 to 10,000 rpm for applications such as premixes, balms, food gums and polymers. High-speed models boast mixing speeds up to 30,000 rpm for applications like tissue and cell homogenization.

低通量批处理分散剂和内线分散器的设计旨在处理26毫升至2升体积的样品。高通量批量分散器可容纳最多50升量的样品。
D - Lab Disperser Voltage
(back to chart)
120-volt connections are suitable for standard laboratory power outlets in the United States.
400-volt connections require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.
E - Speed Control
(back to chart)
E1: Stepless Lab Disperser
Stepless lab dispersersoffer a full range of speed controls including small rpm increments for operations calling for specific mixing speeds.
E2: Fixed Lab Disperser
Fixed lab dispersersdo not include speed range controls. These models are optimal for recurring mixing operations specifying one mixing speed.
F-实验室分散器控制器
(back to chart)
F1: Analog Lab Dispersers
模拟实验室分散器控制器include 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：数字实验室分散器
Digital lab disperser controllersinclude a speed dial with LED readout of current mixing speed. Certain digital models, likeIKA’s ULTRA-TURRAX T 65disperser, include red emergency stop buttons for immediate shutdown.
G - Special Lab Disperser Features

G1: Autoclave-Safe Lab Dispersers
Certain models, likeIKA’s ULTRA-TURRAX T 25，与通压安全的分散元件兼容，用于免提灭菌。
G2: Lab Dispersers with Data Export
IKA’s ULTRA-TURRAX Tube Drive systemincludes software to document performance and program saved methods as well as a USB interface to export data.
