GVS ABLUO Regenerated Cellulose (RC) Syringe Filters, 0.7/0.45 µm, 25 mm, 50/Pk - GF25BNPGR004AL01

GVS casts its own microporous membranes and assembles them into finished syringe filters under one roof, rather than sourcing either component externally. Individually packaged and pre-tested, a syringe filter needs no functional check before use the way a shared reusable holder does. The RC membrane handles aqueous and solvent samples in the same pass while staying stable in DMSO, aqueous buffers, and organic solvents and forms hydrogen-bonded water layers resisting protein adsorption. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use and maintains a low-dead-volume internal flow path. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Prefiltration

• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane
• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Glass fiber prefilter stage sustains flow through particle-laden, hard-to-filter samples

Membrane Characteristics

• Rigid membrane construction prevents collapse under the differential pressures of manual syringe filtration
• Suitable for plasma protein precipitation supernatant filtration before LC-MS/MS injection
• Continuous, non-fibrous film structure resists fiber shedding unlike loosely bonded depth media
• Cellulose's hydroxyl-rich, hydrogen-bonded surface adsorbs far less protein than synthetic filter membranes
• Non-esterified cellulose structure resists acetone and ketone solvents unlike CA or nitrocellulose

Housing Characteristics

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Stable across the full aqueous pH range in routine sample work
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation

Particulates in your buffers, reagents, and aqueous samples slow your preparation and throw off its consistency. General-purpose aqueous filtration supports the sample types you handle every day across your water-analysis and general analytical workflows.

• Fermentation QC - Clarifies fermentation broth samples for rapid glucose, ethanol, and organic acid monitoring in process analytical testing.
• LC-MS Sample Prep - Limits extractable interference with electrospray ionization, supporting sensitive LC-MS/MS quantitation of trace analytes.
• Toxicology Screening - Clarifies blood and urine extracts ahead of LC-MS or GC-MS drug testing, protecting sensitive mass spec ion sources.
• ELISA Sample Prep - A hydrophilic, low non-specific binding surface minimizes antibody and antigen loss ahead of sandwich ELISA quantitation assays.
• HPLC Analysis - Minimizes extractables in critical HPLC sample preparation, ensuring cleaner chromatograms and accurate data generation.
• Drug Discovery Prep - DMSO tolerant RC clarifies compound library solutions in DMSO ahead of biological activity and potency screening assays.
