Do you know the difference between a homogenizer and a DC blender?
Homogenizers and blenders are some of the most widely used laboratory benchtop equipment. While they look similar, they are different and
there are some considerations to take into account when choosing one over the other. Learn how to select based on your needs and sample type.
Stirring and mixing are basic procedures in the laboratory. These operations enable laboratories to achieve different goals: from the manufacture of final products to the preparation of samples for further analysis.
The market offers many options for this, which often look similar but can be very different, such as homogenizers and DC mixers.
Do you know how they differ and how to choose? We hope to provide you with some help in differentiating between the two options and recommending which one to use based on your needs and sample type.
The first important consideration is the sample type and solubility of the ingredients.
Flow-through agitators are typically used in applications where one or more soluble components are agitated and mixed.
If your goal is to mix two or more insoluble media, you will need a homogenizer to break up the particles and form a stable mixture.
In addition to mixing, homogenizers can also be used to emulsify, suspend, grind, disperse and dissolve a variety of samples.
Besides this significant difference, other essential characteristics to consider that differentiate the two instruments include:
1. Viscosity
Rotor/stator homogenizers are optimized to work best with samples that have low viscosities.
DC stirrers are able to accept very viscous samples and are suitable for applications where the sample increases in viscosity during the stirring process.
2. Capacity
Rotor-stator homogenizers can process relatively small volumes of fluid (up to about 2.5 liters).
DC mixers are suitable for very large capacities, up to 100 litres.
3. Speed
Homogenizers operate at very high minimum and maximum speeds (3,000 to 25,000 rpm for the new OV 625 Digital). In these applications, top speed is very important as it significantly reduces processing time and prevents sample damage due to heating.
The DC agitator also operates at very low speeds, with the top speed still lower than that of a homogenizer.
