Membrane filters

LABSOLUTE® offers a wide selection of membrane filters for microfiltration. You can choose between several membrane materials, diameters and pore sizes. Usage of membrane filters is recommended both for filtration of air and fluid and is optimally suited in particular for retention of very small particles. Precisely defined micro pores and exceeding stability - this combination makes it a good choice for applications in the microbiological sector, as well as in the pharmaceutical, food and water analysis industry.

Cellulose acetate membranes are characterized by an extraordinary high flow capacity and dimensional stability. The filters have good thermal resistance and can be used in various applications.

• Hydrophilic
• Low protein binding capacity
• Maximum operating temperature: 135 °C
• Non-sterile
• Autoclavable at 121 °C

The uniform pore structure of the LABSOLUTE® nitrocellulose membranes allow high throughput and diffusion rates and guarantee ultrapure and consistent results due to a very low extent of extractables.

• Hydrophilic
• High protein binding capacity
• Maximum operating temperature: 180 °C
• Autoclavable at 121 °C
