Thumbnail Filmstrip of Glass Fiber Syringe Filters, 1.2um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 500/Pk Images
Featuring a naturally hydrophilic borosilicate glass fiber depth medium with a 1.2um nominal particle retention, these 25mm syringe filters deliver rapid clarification of heavily loaded aqueous and organic samples. The glass fiber media is housed in a transparent polypropylene housing measuring 33mm in diameter, with a 25mm membrane diameter and a 4.6 cm2 effective filtration area. A female Luer-Lok inlet and male Luer Slip outlet provide secure, leak-resistant connection to standard syringes, and the nonsterile format is supplied 500 per pack.
Key Glass Fiber Media Characteristics
- Naturally hydrophilic borosilicate glass fiber that wets out readily without surfactants for fast, consistent flow.
- 1.2um nominal particle retention suited to high particulate loads rather than absolute screening.
- Depth filtration structure captures particles throughout the media for high dirt-holding capacity and increased throughput.
- Ideal prefilter for protecting and extending the life of downstream membranes.
- Broad compatibility with aqueous and organic solutions across diverse sample types.
Key Construction Characteristics
- Transparent polypropylene housing, ultrasonically welded and integrity tested to eliminate filter bypass.
- Female Luer-Lok inlet and male Luer Slip outlet (Luer-Lok/Luer Slip) connection.
- 33mm housing diameter, 25mm membrane diameter, and 4.6 cm2 effective filtration area.
- Holdup volume less than 100 microliters and a maximum operating pressure of 80 psi.
- Nonsterile, supplied 500 per pack, with a maximum operating temperature of 90 degrees C (194 degrees F).
This filter maintains reliable, reproducible flow when processing samples with heavy particulate burdens, delivering clarified filtrate while preserving sample integrity. The high dirt-holding depth structure withstands demanding loads and protects sensitive analytical instrumentation downstream. Each device is integrity tested and clearly labeled with material and pore size for confident identification at the bench.

- Prefiltration of Heavily Loaded Samples The high dirt-holding glass fiber depth medium clarifies turbid and particulate-rich samples that would quickly blind a screen membrane.
- Membrane Protection Serves as a prefilter ahead of finer membranes to extend their service life and prevent premature clogging.
- Environmental Sample Preparation Removes suspended solids and grit from environmental samples prior to analysis.
- HPLC and Chromatography Sample Prep Clarifies sample matrices to protect columns and instrumentation during high-particulate analytical workflows.
- Biological Fluids and Protein Solutions Provides rapid clarification of biological fluids, buffers, and protein-containing aqueous solutions.
- Cannabis Potency and Pesticide Testing Prepares heavily loaded extracts for downstream analytical testing with high throughput.
