SPE Disks and Cartridges
Waters Corp Waters Vac Cartridge, Aminopropyl (NH2), 100 mg, 55–105 μm
These cartridges feature a moderately polar, silica-based bonded phase with a weakly basic surface. They are designed for use with vacuum manifolds and automated SPE instruments for various extraction applications.
- Moderately polar, silica-based bonded phase with a weakly basic surface.
- Functions as polar sorbent for acidic/basic analytes or weak anion exchanger below pH 8.
- Extracts phenols, pigments, petroleum, saccharides, and drugs/metabolites.
- Syringe-barrel format compatible with vacuum manifolds and automated SPE.
- Poly-foil pouch maintains product integrity and purity.
- 20 μm frit (HD/UHMW polyethylenes) offers good flow, low extractables, solvent resistance, and depth filtration.
- Enables easy, spill-free transfer and extraction of solvents and samples.
Hach Company Prefilters, Polypropylene, 90 mm, 25/PK
Xenosep brand ValuSep™ SPE Filters for EPA Method 1664A are designed to provide high recovery and low blank values in Horizon SPEDEX and SPE Manifold applications. Chemically treated with a proprietary reverse phase adsorbent, single layer borosilicate glass ValuSep™ SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 10 minutes with significantly faster filtration times for 1 L NPDES-type samples. ValuSep™ SPE Filters offer high recoveries and low blanks at a great price.
Waters Corp Waters Oasis MCX Vac Cartridge, Mixed-Mode Polymeric, 1 cc, 30 mg, 30 μm
These 1 cc Oasis MCX cartridges feature a novel, mixed-mode polymeric sorbent, optimized for high selectivity and sensitivity in extracting basic compounds. Water-wettable for consistent performance, they simplify sample preparation and are ideal for vacuum manifolds and automated SPE instruments.
- High selectivity and sensitivity for basic compounds.
- Water-wettable design ensures consistent performance even if dry.
- Dual modes of retention: ion exchange and reversed-phase.
- Broad pH stability (0-14) allows flexible method development.
- Superior binding capacity vs. other SPE sorbents.
- Prevents analyte breakthrough or recovery loss.
- 1.0 meq/g sulfonic acid ion exchange capacity.
Waters Corp Waters Vac Cartridge, WAX, 1 cc, 30 mg, 30 μm
The 1 cc Oasis WAX cartridges contain the Oasis WAX sorbent, a polymeric reversed-phase, weak anion exchange mixed-mode sorbent optimized for fast, simple, and highly selective sample preparation of strong acidic compounds. The Oasis WAX sorbent is water wettable, maintaining its capability for higher retention and excellent recoveries even if the sorbent runs dry, eliminating the need for extraordinary steps to prevent drying out during critical steps prior to sample loading.
- Polymeric reversed-phase, weak anion exchange mixed-mode sorbent for strong acidic compounds
- Water wettable to maintain retention and recovery even if sorbent runs dry
- Mass spectrometry compatible
- Copolymer sorbent substrate
- Mixed mode functionality
- Not endcapped
- Ion exchange capacity of 0.6 meq/g
- Constructed from polypropylene
- pH range of 0 to 14

Medchemexpress LLC Afimetoran (Synonyms: BMS-986256) 300mg | CAS No. : 2171019-55-7
Afimetoran (BMS-986256) is an orally active, selective, and highly bioavailable TLR7/8 antagonist. Afimetoran (BMS-986256) can inhibit TLR7/8 activation of the NF-κB pathway and reverse TLR7 mediated resistance to steroid induced apoptosis in plasma cell like dendritic cells (pDCs). Afimetoran (BMS-986256) can be used for research on inflammation and autoimmune diseases (systemic lupus erythematosus).
