Filter paper, qualitative

Fast filtration, smooth.

Medium fast, 4 - 7 µm.

• time saving, because folded filters have a larger surface area
• filter faster than comparable circular filters
• for medium to fine precipitates and general laboratory work
• Weight: 68 g/m²
• Thickness: 0.15 mm

Medium filtration, smooth.

Medium speed, smooth.

For detecting nutrients available to plants, low in nitrogen and phosphorus.

Circles and sheets. Qualitative. The most widely used grade of filter paper.

Medium fast 4 to 7µm

• thin filter paper
• for medium to fine precipitates and general laboratory work
• Weight: 68g/m²
• Thickness: 0.150mm

Highly pure filter paper (approx. 0.08% ash) recommended for precise identification of materials and for sample preparation prior to sensitive detection methods. These filter papers are perfectly qualified for food control according to LFBG paragraph 64 para. 1 and 2, beverage analysis and environmental monitoring.

• Made of the same raw materials (super-refined cotton linters and cellulose) like quantitative filter papers
• High stability and durability due to alpha-Cellulose content above 95%

Housing MBS. SFCA / CA (Surfactant-free Cellulose Acetate) membrane. For sterile, particle free, ultrapure filtration of small volumes of liquid up to approx. 100 ml. Colour coded and printed for easy membrane and pore size identification. With hydrophilic cellulose acetate membrane for minimum adsorption. Ready-to-use. With female luer-lock inlet, male luer slip outlet.

Qualitative. Folded (pre-pleated) version of Number 2.
