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 membrane filters suitable for use in the Microsart™ e.motion are individually sterile-sealed,without protective paper on top of each filter, in a specially designed individual package on a band. For complete traceability, the membrane filter type, diameter, lot number and a unique serial number are printed on the package of each membrane filter unit.

All Microsart membrane filters are "multi-fit" and can be used in all standard dispenser systems.

The membrane filters have a diameter of 47 mm or 50 mm, and are white, green or grey with a high-contrast 3.1 mm grid.

Standard Grade Regenerated Cellulose (RC) is a clear, flexible and sturdy dialysis tubing. This tubing is ideal for a broad range of applications in which there is a significant size difference between the MW species being separated, including sample preparartion, desalting, buffer exchange, pH change, protein purification. Offering a good chemical compatibility, Standard Grade RC can be used with dilute strong acids and bases, concentrated weak acids and bases, most alcohols and some mild or dilute organics, including DMSO. Standard RC can tolerate pH 2 to 12 and temperatures 4 to 121 °C
