Thumbnail Filmstrip of Glass Fiber Syringe Filters, 1.0um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a naturally hydrophilic borosilicate glass fiber depth medium with a 1.0um nominal particle retention, these 25mm syringe filters deliver fast prefiltration of heavily loaded aqueous and organic samples. The glass fiber media is held in a transparent polypropylene housing with a Luer-Lok inlet and Luer Slip outlet, and each unit ships nonsterile in packs of 500. The depth structure traps suspended solids throughout its thickness, providing high dirt-holding capacity and sustained flow under load.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate glass fiber that wets out readily with aqueous samples without pretreatment.
- 1.0um nominal particle retention rather than an absolute pore size, characteristic of a depth filtration medium.
- Depth structure provides high particulate loading capacity, capturing suspended solids throughout the media thickness.
- Supports high flow rates and increased throughput, accelerating sample preparation.
- Well suited as a prefilter to protect and extend the life of downstream membranes.
Key Construction Characteristics
- Transparent polypropylene housing for sample visibility and broad chemical compatibility.
- Female Luer-Lok inlet and Male Luer Slip outlet for secure syringe attachment and convenient dispensing.
- Nonsterile, supplied 500 per pack.
- Integrity tested construction with an ultrasonic weld to help eliminate filter bypass.
- Each filter is labeled with its filter material and pore size for easy identification outside the original packaging.
This configuration maintains consistent flow even with viscous or particle-rich samples, reducing clogging and sample loss. The low hold-up volume design helps preserve costly or limited samples, while the inert polypropylene housing protects sample integrity across a wide range of solutions.

- Prefiltration of Heavily Loaded Samples The 1.0um glass fiber depth medium clarifies particle-rich liquids before they reach finer membranes or instruments.
- Downstream Membrane Protection Used as a prefilter, it captures coarse particulates that would otherwise blind a 0.45um or 0.22um membrane.
- Environmental Sample Preparation High dirt-holding capacity makes it suitable for clarifying turbid environmental and water samples.
- HPLC Sample Preparation Removes suspended solids from samples to protect chromatography columns and detectors.
- Biological Fluid and Protein Solution Clarification The hydrophilic medium clarifies protein aqueous solutions and biological fluids ahead of analysis.
- Buffer and Reagent Clarification Rapidly removes particulates from buffers and reagent solutions during prep.
