Filter paper, qualitative

Recommended for the detection of very fine traces of light-coloured particles and precipitates.

• Made of pure celluloses and with constriction of black additives
• White and light-coloured particles can be detected easily by the strong contrast to the black filter paper
• Weight 95 g/m²
• Thickness 0,2 mm
• Filtration speed acc. to Herzberg 850 s

Slow < 2 µm. Blue ribbon.

• for very fine precipitates and small particles
• for soil analysis
• for BaSO₄ (hot precipitate), PbSo₄, Cu₂O, ZnS, NiS
• Weight: 84 g/m²
• Thickness: 0.16 mm

SEPARA integrates in one single device auto-sampler vial, filtration membrane, plunger, and cap/septa. The single step filtering process is efficient and saves time. Fast and simple to use. Reducing sample loss. After filtration the sample is ready to use in most standard autosampler. The pre-slit cap ensures easy and clean transfer of sample. 5 different septa material, PP vial with Ø 12 x 33 mm, Filtering capacity 0.48 ml, dead volume <30 µl, maximum operating temperature 50 °C

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%

The strips remove excess liquids on microscope slides and thus dry quickly, cleanly and easily stained specimens for microscopy. 1 block = 50 strips.

Filter papers in a flat, quadrant folded format to fit conical filter funnels. Easy and time-saving handling for analyses with high sample throughput.
