Inside the syringe filter polytetrafluoroethylene is used as membrane material. The hydrophobic PTFE membrane is very resistant towards all kinds of solvents as well as acids and bases. Flushing with alcohol, followed by water, makes the originally hydrophobic membrane more hydrophilic. Labeled for method validation and certification. All CHROMAFIL filters are autoclavable (121 °C and 1.1 bar for 30 min)!Method FiltrationBrand CHROMAFIL XtraType Syringe filter, labeledHousing type Wheel-like shaped housingHardware Polypropylene (PP) housing with filter membraneMembrane type Polytetrafluoroethylene (PTFE)Membrane properties HydrophobicFilter type 13 mmEffective membrane diameter* 15.6 mmMembrane pore size 0.2 µmCode type LabeledColor code (top) LabeledColor code (bottom) ColorlessInlet Luer lock (top)Outlet Luer tip (bottom)Sample volume 1 ≤ 5 mLRecommended application(s) Nonpolar samples, Suitable for UHPLC columns packed with particles < 3 µm, GC, SFC, …, Very resistant towards all kinds of solvents as well as acids and basesSterile NoBinding capacity (proteins) Moderate–highDead volume 30 µLEffective filtration area* 1.9 cm²Storage temperature 15–25 °C / 59–77 °FPackaging dimensions 110 x 110 x 105 mm / 4.33 x 4.33 x 4.13 InchGross weight (incl. packaging) 209 g / 0.46 lbsHazardous material NoRemark*Standardized measurement since Mai 2023.
