Syringe Filters

Photo of Nitrocellulose Mixed Esters Syringe Filters w/Acrylic Housing
These membranes are characterized by a smoother and more uniform surface than pure nitrocellulose filters. Also, the color contrast provided by the filter surface facilitates particle detection and minimizes eye fatigue. Compared to pure nitrocellulose filters, mixed ester membranes have a smoother and more uniform surface as well as offer color contrasting, making it easier to detect particles.
