Break the Curse of Particle Size Calculations

Every now and then I’ve had to calculate the results of a sieve test: I’d get the sieves and sample loaded on the shaker,  run the shaker, then realize I’d have to start over because I forgot to get the empty weight of each sieve. Or I’d have to carefully brush out the sample onto a balance.

What is The Function of a Sieve Shaker?

Posted by Art Gatenby on Oct 17, 2013 4:56:00 PM

 

Visitors to our web pages often arrive with the question, “What is the Function of a Sieve Shaker?

The simple answer is “to expose the particles in a sample to all the openings in each sieve in a stack”. A sieve stack is the result of fitting each sieve to be used in a given particle size analysis into the one above. The sieve with the largest mesh holes is at the top with each subsequent sieve of a tighter mesh size than the one above it.

Advances In Sieves: Sieves Able to Strip Molecules From Fluids

Posted by Art Gatenby on Nov 19, 2012 2:32:00 PM

Sieves make understanding the world around us not just possible, but also easier.

And with the advancement of sieves, not only are we able to separate dry particle, but also sift molecules from fluid as well. With molecular sieves developed by MIT, we can now strip a molecule’s individual parts gives us a better understanding of how things come together and work, such as diseases or even DNA.

Is Particle-Size Analysis Boring? Trivial? Amazing? Exciting? Vital?

When I tell people at cocktail parties that we specialize in Particle-Size Analysis. I usually get a polite response of ------ “OH !!,”   which translates to “So who cares?”
