Hydrophobic PTFE Syringe Filter
Hydrophobic PTFE Syringe Filter
Product Description:
PTFE (Teflon?) membrane is hydrophobic and is designed to filter most aggressive solvents, acids, and base samples. The PTFE syringe filter is available with or without a glass fiber prefilter. 50 mm also available.
Teflon? syringe filter is designed to filter most aggresive solvents, acids, and base samples. These units are recommended for HPLC solvent and gas chromatography filtration. They are excellent for filtering and degassing solvents before analysis.
The membrane filter in the Teflon filter is naturally hydrophobic Teflon (PTFE), which is autoclavable and will not release extractables into the sample.
The Teflon with glass fiber prefilter syringe filter features a 1.0 micron glass prefilter over a Teflon filter. This filter is designed to sterilize or clarify most aggressive solvent, acid and base samples with a high particulate load with high throughputs and quick flow rates.
