Stainless steel filtration unit with 2-liter infusion cylinder. Features: • This unit is ideal for the separation of undissolved components Samples for the determination of the eluted fractions of sludge samples with water. • With a capacity of 2 liters, the unit with the entire Sample volume can be filled and the large opening for easy filling of the liquid. • The pressure filtration avoids the loss of volatiles. • A filter area of ​​130 cm2 guarantees short filtration times. Specifications: • Chemical compatibility: - As for stainless steel, PTFE, silicone and Viton - If necessary, the silicone O-rings against EPDMO-rings (part number 6982071); Viton O-rings (6982070) or PTFE O-rings decreases (the maximum operating pressure to 4 bar.; The O-rings of Viton valve with EPDM O-rings; be exchanged 58 psi) (6985184) or silicone O-rings (6985183) will be replaced. • Flow rate for water at p = 1 bar (100 kPa, 14.5 psi): 2 l / min at 0.2 microns, 4.5 l / min at 0.45 micron, 11 l / min at 0.8 micron pore size • Filtration area: 130 cm2 • Membrane filter size: 142 mm • Weight: 12 kg • Thread for the ports: M 12 +1 female threads • materials upper, lower part: - Corrugated iron. Locking brackets, legs, cap and valve body: stainless steel 1.4401 (AISI 316) - Filters and support backup security: PTFE-coated stainless steel. - O-rings (130 +4 mm) in the head and the filter support: Silicone - O-rings in the valve (3 +1.5 mm): Viton - Seals (valve and cap): PTFE • Maximum operating pressure: 7 bar (700 kPa, 101.5 psi) • Matching Filter diameter: 142 mm membrane filter (prefilter 130 mm) • Sterilization by autoclaving (max. 134 ° C) or dry heat (max. 180 ° C).
