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

Electrical Conductivity is the ability of a solution to pass an electrical current. All ions present in a solution contribute to the conductivity measurement. How well a solution conducts electricity depends on several factors such as concentration, mobility and valence of the ions present.

Electrical conductivity measurement using digital conductivity probes is generally a reliable, sensitive and low-cost method.  Surveillance of feed, permeate and reject quality and estimation of the total number of ions in a solution in the membrane filtration systems can all be performed using online and real time conductivity measurement techniques.

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.

Sterlitech had the pleasure of attending our local CannaCon this month. CannaCon is the largest event in the cannabis industry, with hundreds of exhibitors from around the country. The conference has dates in Oklahoma City, Detroit, and Springfield, but Seattle is its flagship city. Industry experts in growing, processing, packaging, marketing, financing, IT, and business operations all meet at this event.

On the floor at the Seattle show, it was clear that this year’s conference was catering to an advanced cannabis market. There was a wide variety of products and services showcased, to match the diversity and maturity of Seattle’s market. A special area of emphasis for this year was cannabinoid and terpene profiling. We were excited to see all the solvent-based (and solvent-free) extraction technologies, along with distillation equipment.
