What is a Lab Disperser? How is it Different from a Homogenizer?
Laboratory dispersers，有时被称为高速剪切刀或转子定子混合器，是一种设计用于分散的架空搅拌器，而不是混合化合物。与均化混合两种或更多种可混溶成分的均化相反，分散剂由于液 - 液或固液相分离而产生两个或更多个不混溶的组分的混合物。流体分散体包括乳液（分散到另一个液体中的液体颗粒）或研磨分散体（分散到液体中的固体颗粒）。
什么是实验室分散者用于？
实验室分散器用于生物技术行业，形成液体生物分子缩合物，食品工业生产香醋或均质牛奶，制药工业，创造面霜，软膏和酱料，以及化学工业制造聚合物，如橡胶或胶乳制造聚合物。
扩散器s 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.
A - Lab Disperser Configuration

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 - 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 -实验室扩散器最大的速度
(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.

E1：无级实验室分散器
无级实验室分散者提供全系列的速度控制，包括呼叫特定混合速度的操作的小RPM增量。
E2: Fixed Lab Disperser
固定实验室分散器不包括速度范围控制。这些模型对于具有指定一种混合速度的反复混合操作是最佳的。
F - Lab Disperser Controllers

F1：模拟实验室分散器
模拟实验室分散器控制器包括快速拨号和电源开关。数字模型的经济替代方案，这些单位不包括带有计时器和数据导出功能的板载软件。
F2: Digital Lab Dispersers
Digital lab disperser controllers包括具有电流混合速度的LED读数的快速拨号。某些数字模型，就像IKA’s ULTRA-TURRAX T 65Disperser，包括红色紧急停止按钮，用于立即关闭。
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：具有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.
