What is a Lab Disperser? How is it Different from a Homogenizer?
laboratory dispersers，有时被称为高速剪或转子定位器搅拌机，是一种旨在分散而不是混合化合物的高架搅拌器。与均匀混合两个或多个可混杂的组件的均质剂相反，分散剂由于液体液体或固液相分离而产生了两个或多种不混溶的成分的混合物。流行的分散体包括乳液（液体分散到另一种液体中）或研磨分散体（固体颗粒分散到液体中）。
实验室分散器是用什么？
生物技术行业使用实验室分散剂来形成液体生物分子冷凝物，食品工业以生产醋汁或均质牛奶，制造奶油，油膏和咸水的制药行业以及化学工业以制造聚合物，例如橡胶或乳胶。
Dispersers 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-批处理实验室分散器
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 - 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.
B - Lab Disperser Maximum Speed
(back to chart)
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.

C - Lab Disperser Maximum Volume
(back to chart)
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.
D-实验室分散器电压
(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.

F1：模拟实验室分散器
模拟实验室分散器控制器包括一个速度表盘和电源开关。这些单元不包括具有计时器和数据导出功能的板载软件。
F2: Digital Lab Dispersers
Digital lab disperser controllers在当前混合速度的LED读数中包括一个速度表盘。某些数字模型，例如IKA ULTRA-TURRAX T 65分散器，包括红色紧急停止按钮以立即关闭。
G - Special Lab Disperser Features

G1: Autoclave-Safe Lab Dispersers
Certain models, likeIKA’s ULTRA-TURRAX T 25, are compatible with autoclave-safe dispersing elements for hands-free sterilization.
G2：数据导出的实验室分散器
IKA的Ultra-Turrax管驱动系统includes software to document performance and program saved methods as well as a USB interface to export data.
H - Lab Disperser Motor Rating
(back to chart)
Models designed for low-volume, low-viscosity stirring contain motors generating 17 – 300 Watts. High-volume, high-viscosity models contain motors generating 500 – 2,200 Watts.
