The MSI®25ES is a presterilized 25mm filter designed to sterilize and clarify aqueous samples up to 100mL. The filter is a nitrocellulose mixed esters of inert cellulose nitrate and cellulose acetate polymers, with a choice of 0.22µm or 0.45µm pore size. The filter™s uniform microporous structure yields fast flow rates and high throughputs. The modified acrylic housing supports the membrane bi-directionally to allow sample injection or aspiration. Units are sterilized by gamma radiation and tested to verify filter and housing integrity. Pore size and filter type are clearly labeled on each unit for quick identification. Maximum operating pressure of 75psi and maximum temperature of 131°F (55°C). Presterilized by gamma radiation and individually blister-packed.

The30E Syringe Filter, a nonsterile 30mm filter with a polypropylene housing and a pore size of 0.45µm. Maximum operating pressure of 130psi and maximum temperature of 356°F (180°C).
