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.

SafetySpace™ Filter Tips leave more space between the sample and the filter than conventional filter tips. This allows pipetting any type of liquid or using any pipetting technique without the risk of the precious sample absorbing into the filter. In effect, this secures 100 % sample recovery and thus greater accuracy. Particularly suitable for pipetting foaming liquids such as buffers and proteins, pipetting solvents, multiple dispensing functions of electronic pipettes, reverse pipetting. Certified DNase, RNase and endotoxin free.
