Regenerated Cellulose Syringe Filters, 0.7/0.22um, 25mm, Luer-Lok/Luer Slip, Nonsterile, 50/Pk
GVS SKU: GF25BNPGR002AL01

GVS ABLUO Regenerated Cellulose (RC) Syringe Filters, 0.7/0.22 µm, 25 mm, 50/Pk - GF25BNPGR002AL01

GVS casts its own microporous membranes and assembles them into finished syringe filters under one roof, rather than sourcing either component externally. A sterilizing-grade syringe filter delivers point-of-use sterile filtration in a single-use format, without the housing and gasket maintenance a reusable stainless steel filter holder requires. RC's natural cellulose adsorbs protein at under half the rate of synthetic membranes while handling aqueous and solvent samples in the same pass and stays stable across aqueous pH 3 to 12. Low-extractable polypropylene keeps sample purity intact through the filtration pass and maintains a low-dead-volume internal flow path. Where bacterial contamination must stay out of the sample, manufacturer-tested retention keeps the instrument and downstream assay protected without a housing to maintain or clean.

Prefiltration

• Naturally hydrophilic borosilicate fiber wets quickly with aqueous samples
• Depth-loading glass fiber matrix captures particulate throughout its full thickness
• Added glass fiber stage extends usable throughput by delaying membrane clogging
• Two-stage construction pairs a borosilicate glass fiber prefilter with the downstream membrane

Membrane Characteristics

• Fixed absolute pore rating keeps results consistent from method to method
• Particles well below 2 microns are removed at the rated pore size
• DMSO and acetonitrile compatibility extends beyond typical PES membrane range
• Cellulose polymer composition allows biodegradation unlike synthetic PES, PVDF, or nylon
• Non-ionic, uncharged surface avoids ion suppression artifacts in LC-MS electrospray analysis

Housing Characteristics

• Housing rated for warm-sample filtration above standard laboratory temperature without softening or seal loss
• Minimal extractable release from the housing supports sensitive analytical work downstream
• The seal formed against the membrane blocks bypass at rated operating pressure
• Withstands standard 121°C steam autoclave cycles without softening or structural distortion

A column clogging mid-run from unfiltered sample can cost you the rest of your analytical day. Pre-injection filtration protects the resolution your methods depend on by clearing particulates ahead of the column and frits.

Wettability

Hydrophilic

• Buffer Prep - Low extractables and a hydrophilic surface make RC filters ideal for clarifying pharmaceutical buffers and aqueous reagents in the lab.
• Drug Discovery Prep - DMSO tolerant RC clarifies compound library solutions in DMSO ahead of biological activity and potency screening assays.
• Toxicology Screening - Clarifies blood and urine extracts ahead of LC-MS or GC-MS drug testing, protecting sensitive mass spec ion sources.
• Water Testing Prep - A spontaneously wetting surface clarifies environmental water samples for metals, nutrients, and contaminant testing workflows.
• Pharmaceutical Prep - Delivers low extractables when filtering aqueous drug formulations and vehicles ahead of potency and stability assay testing.
• Spectroscopy Prep - Ensures clean baselines in UV-visible spectroscopy by effectively removing particulates without adding interfering artifacts.
