GD/X 13mm Syringe Filter, Nylon Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6870-1302

Whatman GD/X Nylon Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6870-1302

Whatman ties GD/X prefiltration performance to one closely held fiber-grade standard applied at every production run, keeping results repeatable from one manufacturing lot to the next. Sterilizing-grade syringe filters deliver sterile-grade retention as a single-use format, eliminating the autoclaving and cleaning cycle a reusable sterile filtration setup would require. Nylon pairs with a glass-fiber prefilter for turbid samples and delivers bacterial retention at the rated pore size. Polypropylene construction resists chemical degradation from routine sample matrices while pressing snugly against the membrane during the pass and maintains structural integrity through elevated-temperature sample preparation. 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.

Membrane Characteristics

• Amorphous-crystalline nylon blend composition doubles membrane burst strength over homopolymer nylon
• Integrated glass-fiber prefilter increases dirt-holding capacity
• Resonance-stabilized amide bonds anchor nylon's resistance to alkaline hydrolysis
• Low extractable contribution to sensitive analytical preparations
• Common ketone solvents, including acetone, methyl ethyl ketone, and methyl isobutyl ketone, cause no attack

Housing Characteristics

• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Housing retains dimensional stability and seal integrity through elevated-temperature operation up to 121°C.

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine the same way every time you run it. Ask our customer support technicians for chemical compatibility guidance on your specific filtration application.

Hydrophilic

• Mining Process Waters - Clarifies process water samples from hydrometallurgical operations, removing solids ahead of ICP-MS trace metal quantitation.
• Environmental Extract Prep - Clarifies water and soil extracts ahead of trace metals or pesticide-residue analysis for accurate results.
• Amino Acid Profiling - Clarifies aqueous sample digests for HPLC and LC-MS amino acid analysis in food, nutrition, and fermentation monitoring.
• Ink and Dye Filtration - Filters aqueous and solvent-based inks and dyes, removing pigment agglomerates ahead of color strength analysis.
• Content Uniformity Testing - Removes insoluble excipient and binder particulates that would skew spectrophotometric or HPLC potency-assay results.
• Chemical Analysis - Withstands aggressive bases and alcohols, ideal for tough chemical compatibility filtration challenges in routine analysis.
