Heartworms (Dirofilaria immitis) are a species of parasitic roundworms that primarily infect dogs, but can also infect cats, wild canids, and, in rare cases, even humans. They are found in every state in the country and spread from one host to the next through mosquito bites, which deposit larval heartworms into the new host when they feed.  Since their lifecycle depends on mosquitos, infection rates are on the rise as human activities, such as irrigation and urban development, create new habitats suitable for mosquitos. Heartworm infections develop slowly, with symptoms often presenting themselves only months past since the initial transmission.

The first symptoms are innocuous enough, just a slight cough. As the worms grow and lodge themselves in the arteries leading into the heart and lungs, the coughing becomes worse and persistent.  The dog will exhibit difficulty breathing and a reluctance to exercise, which gets worse as time goes on. Eventually, a severe infection

(Updated Feb, 2017) If you were to casually browse through Sterlitech's website, you may find that we have an incredible range of filter options. The casual browser may certainly find themselves overwhelmed looking for the right filter for their application. One of the most important aspects of filter selection is pore size, which determines the size of largest particles that can pass through the filter. Pore sizes are usually placed in one of two categories: nominal or absolute. So what's the difference? Nominal pore sizes A nominal pore size rating refers to a filter capable of preventing passage of a minimum percentage (usually between 60% and 90%)of solid particles of greater than the stated pore size, which is normally expressed in micrometers or microns. Conditions during filtration, such as operating pressure, shape of the particles and the concentration of particles, have a significant effect on the retention of

Sterlitech will be attending the 42nd Annual NAOSMM Conference and Trade Show! From July 26 - 31, Kristina and Brandon will be on hand at Booth #83 to answer your questions about Sterlitech's laboratory equipment and filters. If you want to send them your questions ahead of time, feel free to shoot them an email: Kristina Shahbazian: [email protected] Brandon Nolan: [email protected]

Here's a new animation showing the basics of operating Sterlitech's Sepa CF Membrane Test System. Each test system allows users to simulate the dynamics of larger membrane filtration systems by manipulating the control valves to achieve the desired pressure and flow rates. The system is equipped with one or two Sepa CF Cells and a suite of in-line sensors that automatically record and display the experimental data in real time. All Sepa CF test systems are individually manufactured according to the customer's requirements. Contact us to learn more.
