Ultrafine particles (UFPs) belong to a class of primary air pollutants called particulate matter (PM). Other types of PM include coarse particulate matter (PM10) and fine particulate matter (PM2.5). With a diameter of 0.1 micron or less, UFPs are the smallest known particles of PM. To put its relative size into perspective, UFPs measure 700 times smaller than the average diameter of a human hair.

The small size of UFPs and their vast numbers has led scientists to further investigate their properties and potential health impacts. Similar to other PM, UFPs can penetrate deep into the lungs; however, it’s unique ability to pass through the respiratory membrane, enter the bloodstream, and travel to the body’s organs (a process called translocation) poses further health concerns than its larger relatives.[1]

UFPs are a product of combustion processes emissions. Emission inventory studies have shown that road vehicles

After attending MJBizCon this past December, Sterlitech can attest that this year’s conference was bigger than ever with 40,000 people from 75 countries in attendance. Our Sales Engineer, Kensen Hirohata, managed our booth for the duration of the event with visits from other members of our staff, including Sara Azari, Application Engineer and Mark Spatz, President and Founder. Below are some of our key takeaways:

Organic Solvent Nanofiltration (OSN) Membranes in Cannabis/Hemp Extraction

Let’s start 2020 with some reflection on our top 5 blog posts in 2019. Read on to find the answers to a couple of common FAQs and learn about one of nature’s most powerful filters: oysters!

1. Defining a Pore Size and Sterile Filtering; 0.2 Micron vs. 0.22 Micron. What’s the difference?

Find out what “pore size” really means, how you can test a filter’s performance with a bubble point test, and other factors you should consider when selecting the correct pore size for your application

What is Membrane Distillation?

Membrane Distillation (MD) is a relatively new and promising separation technology that is an alternative to more energy intensive methods such as reverse osmosis or distillation. MD is a thermally driven process where only vapor molecules transfer through a hydrophobic (water repellent), microporous membrane.
A typical membrane distillation technique features a membrane filter sandwiched between cold solution on one side and hot solution on the other side. The driving force of the MD process is the partial vapor pressure difference induced by the temperature difference across the hydrophobic membrane. The vapor then condenses on the cold side to produce the distillate.
