Syringe Filters

Ready-to-use & disposable filtration units

CHROMAFIL® syringe filters

Disposable syringe filters CHROMAFIL® are ready‑to‑use filtration units, which are filter elements incorporated in a polypropylene housing. Because every filter is only used once, contaminations are avoided. By using CHROMAFIL syringe filters unwanted particles are removed which can otherwise cause contamination and clogging of sensitive instrumentation. So, filtering your samples leads to an increase of lifetime and less downtime of chromatographic columns and equipment, gives more consistent and reproducible results and thereby saves time and money.

Your benefits when using CHROMAFIL syringe filters:
- Different membrane types to meet multiple filtration needs
- Low content of extractable compounds
- Fast flow geometry for easy filtration
- Low hold-up volume for maximum filtrate recovery
- HPLC certified

Membrane type

CHROMAFIL® Syringe Filter 15mm GF 1um MS

REF: 729034

CHROMAFIL® Syringe Filter 15mm GF 1µm MS. Inside the syringe filter a glass fiber is used as membrane material. The hydrophilic GF membrane is an inert filter for solutions with high loads of particulate matter or for highly viscous solutions (e.g., soil samples, fermentation broths). The nominal pore size of 1 µm allows higher flow rates than small pore filters. Membrane material is also used as prefilter for CHROMAFIL combi filters, they prevent plugging of the main membrane. All CHROMAFIL filters are autoclavable (121°C and 1.1 bar for 30 min).
