Sterlitech’s team had a wonderful time exhibiting at Pittcon 2019 last month. It was great to connect with our partners, vendors, and customers in person. We had the chance to see familiar faces at the ILDA reception and wander the expo hall among over 400 other booths. Our team also enjoyed a healthy dose of Philly cheesesteak.

Pittcon is the world’s leading annual conference and expo for laboratory science. Attendees from industry, academia, and government come from around the world to participate in the conference and exposition. At the Sterlitech booth, we were happy to see a variety of attendees that had come from Pittsburg, Colombia, and everywhere in between. Users discussed their utilization of PTFE filters for HPLC, gold-coated polycarbonate membranes for IR spectroscopy, and solvent-resistant vacuum pumps. We also observed a lot of work being done in microplastics research and characterization, which is an interesting application for track-etch membranes - they can be used in

Our Application Engineer, Sara Azari, will be presenting at the upcoming annual meeting for North American Membrane Society (NAMS) in Pittsburg, on Monday, May 13th from 7-10 pm.

Stop by to chat with Sara during her poster presentation entitled, “A surface modification of forward osmosis (FO) membranes to enhance dye retention and fouling resistance for the treatment of industrial wastewater”.

For particle and gravimetric analyses such as sediment testing of coolants and machine oils, nylon membrane filters are often utilized due to superior strength, chemical compatibility, and lot-to-lot consistency. Filters with 10 and 20 µm pore size ratings offer fast flow combined with consistent retention and are recommended in GMW16037: Test Method to Quantify Cleanliness of Engine and Transmission Components.1 Unfortunately, these filters have recently become more difficult to source, as some manufacturers have discontinued 10 and 20 µm rated nylon membranes. To address the market need for 10 and 20 µm rated nylon membrane filters, Sterlitech is introducing our new Nylon Cleanliness Test Filters.

These filters are specifically designed for cleanliness testing in the automotive and aerospace industries. They have virtually the same water bubble point specifications, and consequently very similar retention, as the discontinued 10 µm and 20µm rated nylon membrane filters. They also

Unit of Measurement for Electrical Conductivity

The unit of measurement for electrical conductivity is commonly used as one millionth of a Siemens per centimeter (micro-siemens per centimeter or µS/cm). When measuring more concentrated solutions, the units are expressed as milli-siemens/cm (mS/cm). For ease of expression, 1000 µS/cm are equal to 1 mS/cm.

Are you interested in learning more about the membrane filters you use in the lab every day?

Tune in to Sterlitech’s upcoming webinar on April 9th at 8:00 am PT. This webinar will provide an introductory overview of microfiltration membranes.

Join our filtration experts as they discuss characteristics and applications for membrane filters and answer any questions you may have.

.

You'll walk away knowing:

• What microfiltration membranes are and how they work
• How to decide which membrane filter is right for your application
• Where to find additional resources

Sterlitech will be in Philadelphia, Pennsylvania exhibiting our filtration products at Pittcon 2019 . This year, the annual global expo for analytical lab sciences is being held at the Pennsylvania Convention Center. Pittcon is the world’s leading annual conference and exposition on laboratory science.  

Pittcon attracts attendees from industry, academia and government from over 90 different countries. Pittcon offers a unique opportunity to participate in product demonstrations, attend seminars and short courses, and connect with technical experts. This is Sterlitech’s 17th year participating in Pittcon and we are excited to continue sharing our products with the lab science community. 

 This is a follow up to our newsletter article, “New Adapter for testing 25mm Membrane Discs in the HP4750” that went out in November without going through the necessary steps of internal and external reviews and care for content.  We want to make sure we take the necessary steps to make this right by publishing this follow up.

While Sterlitech has observed a growing need in the research community for a high pressure stirred cell to test 25 mm membrane discs, the development of the first prototype of this product was done by our customers/researchers, Christopher M. Stafford, PhD. and Chris Amigo, Machinist, at the National Institute of Standards and Technology. Christopher and his team shared their design with Sterlitech, so we can make this product available to the other researchers in the field, so a wider audience in the research community can take advantage of their design, and we can all push the boundaries of research and science collectively.

We apologize for the confusion,

The Innovator Cross Flow Filtration Kit is a plug and play system designed for conducting lab scale filtration experiments. With a total hold-up volume <1 liter in the test cell and circulation line, this bench-scale cross flow filtration system is also ideal for filtering valuable feed solutions and or small sample volumes. 

This assembly enables microfiltration, ultrafiltration, and nanofiltration separations using Sterlitech’s Innovator (CF016) or Explorer (CF042) membrane test cells. Our flat sheet membranes are available in pre-cut coupons to fit these cells. The system comes complete with a gear pump, feed carboy, stand-mounted membrane test cell, and all the necessary tubing, pressure control valve, flow and pressure sensors.

Features:

• Pressure control valve to adjust the pressure in the system
• Variable speed knob on pump to adjust feed flow rate
• Cell stand for easier access to membrane and tubing
• Stainless steel or inert thermoplastic construction of wetted parts
• Optional conductivity,
