The Cole-Parmer TELOS Nylon Syringe Filter with Prefilter, 30 mm, 0.22 µm, 100 Pack (12916-01) is a filtration consumable for preparing aqueous, alcoholic, organic and biomolecular samples. Its hydrophilic nylon membrane and integrated depth prefilter provide two-stage filtration within a polypropylene housing, making it suitable for high-viscosity and high-particulate samples.
Key Features
- Hydrophilic nylon membrane, offering strong mechanical stability and medium protein binding
- Fine 0.22 µm pore size, supporting removal of fine particles from compatible liquid samples
- Large 30 mm membrane diameter, providing a 4.5 cm² filtration area
- Integrated depth prefilter, adding an initial filtration stage to capture larger particles before they reach the membrane
- Two-stage filtration design, helping reduce membrane clogging and maintain flow during sample preparation
- Suitable for challenging samples, including high-viscosity liquids such as oils and samples with high particulate loads
- Broad solution compatibility, suitable for aqueous and alcoholic solutions and most HPLC solvents
- 90 mL sample-volume capacity, supporting filtration of larger syringe-based sample volumes
- 140 µL retention volume, providing a defined internal hold-up volume
- Solvent-resistant polypropylene housing, designed with nominal extractables for reliable sample preparation
- Secure Luer connections, combining a female Luer-Lok inlet with a male Luer-slip outlet
- Light blue colour-coded seal, helping identify the membrane type while reducing leaks and sample loss
- Pack of 100 filters, supplied in a resealable container for cleaner repeated access
Benefits
- Improves filtration of viscous or particle-rich samples by capturing larger material before it reaches the final membrane.
- Helps maintain flow and extend usable membrane life by reducing premature clogging.
- Supports multiple laboratory workflows using aqueous, alcoholic and compatible HPLC solvent samples.
- Reduces the risk of leakage and sample loss through secure Luer connections and the retainer-ring seal.
- Simplifies membrane identification and stock organisation through the light blue colour coding.
- Supports routine laboratory use with 100 filters supplied in a resealable container.
