Reduce Heterogeneity

Feel confident that your analysis is representative of a population and eliminates the heterogeneity of your samples.

Minimize Variability

For reproducible results, you need to be sure that your sample is prepared consistently.

Eliminate Interference

Don’t let impurities and contaminants be the reason your analysis is inaccurate.

Increase Sensitivity

Sample preparation can enhance the sensitivity of the analysis, allowing the detection of trace levels of analytes that may not have been detected without proper sample preparation.

 


 

Why does Lab Milling and Grinding Matter?

You’ve likely heard the saying, "garbage in, garbage out.” Well, the same applies to your samples! The quality of your sample preparation sets the stage for the accuracy and reliability of your analysis. Milling and grinding are the first steps in creating a sample that's ready for the next stages in your workflow. By reducing the size of your sample particles, you can achieve a homogenous and representative sample that's ideal for analysis.

Take the time to choose the right milling and grinding methods and equipment, follow proper sample handling and safety protocols, and consider your specific application and sample characteristics. With the right approach, you'll be well on your way to obtaining high-quality and pure samples for your research or industrial projects.

In summary, when it comes to milling and grinding for sample preparation, keep these key considerations in mind:
 

  • Choose the right milling and grinding methods based on your sample type and desired particle size.
  • Select appropriate equipment that fits your needs and budget, from manual hand-held devices to automated machines.
  • Follow proper sample handling practices, including labeling, storage, and transportation, to maintain sample integrity.
  • Prioritize safety by following all safety protocols and wearing appropriate PPE when handling milling and grinding equipment.
  • Consider your budget and intended application to find the right balance between cost-effectiveness and quality of results.
  • Consider the sample quantity and specific characteristics for efficient and effective sample preparation.

 


 

Cyrogenic Milling and Grinding

 

Cryogenic Mills


Cryogenic mills use liquid nitrogen or other cryogenic gases to cool down the grinding chamber to ultra-low temperatures, typically below -150 °C. This extreme coldness helps in brittle and heat-sensitive materials, such as plastics, rubber, and biological samples, where maintaining sample integrity is crucial. Cryogenic mills are ideal for preserving the chemical and physical properties of samples, and they can produce fine and uniform particles with minimal thermal degradation.

Ring and Puck

 

Ring and Puck Mills


These mills consist of a stationary ring and a rotating puck that crushes, grinds, or pulverizes materials between them. They are commonly used for pulverizing hard and brittle materials, such as rocks, minerals, and ceramics. Ring and puck mills are versatile and can achieve a wide range of particle sizes, making them suitable for various applications, including sample preparation for X-ray fluorescence (XRF), X-ray diffraction (XRD), and elemental analysis.

High-Energy Ball Milling and Grinding

 

High-Energy Ball Mills


If you're looking for some high-octane grinding action, high-energy ball mills are the way to go! These mills use balls or beads to crush, grind, or impact materials with high kinetic energy, resulting in rapid and efficient size reduction. High-energy ball mills are commonly used for grinding hard and brittle materials, such as metals, alloys, ceramics, and minerals. They are also used for mechanical alloying, mixing, and homogenization of various materials. High-energy ball mills are known for their speed, intensity, and ability to produce ultra-fine particles in a short amount of time.


 

Frequently Asked Questions

Q:

What is the difference between grinding and milling in a laboratory?

A:

The difference between grinding and milling is like the distinction between shredding and chopping. Grinding involves the use of abrasive materials or grinding media to reduce the size of particles, while milling typically refers to the use of mechanical force or pressure to break down materials into smaller particles.

Q:

What lab equipment is used for grinding?

A:

There is various lab equipment used for grinding, depending on the specific application and desired particle size. Common examples include ball mills, swing mills, and jaw crushers.
