SPE Disks and Cartridges
Waters Corp Oasis WAX 1 cc Vac Cartridge, 10 mg Sorbent per Cartridge, 30 µm, 100/pk
reversed-phase, weak anion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong acidic compounds. Since the Oasis WAX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Oasis HLB 5 cc Glass Vac Cartridge, 200 mg Sorbent per Cartridge, 60 µm, 30/pk
The Oasis HLB glass cartridges are optimized for trace analysis at parts-per-trillion (PPT) level. Each lot is tested for the presence of bisphenol A and other phenols and phthalates, assuring that endocrine disruptors can be analyzed to PPT levels.
Waters Corp Sep-Pak Cyanopropyl (CN) Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Oasis WAX Plus Short Cartridge, 225 mg Sorbent per Cartridge, 60 µm, 50/pk
The Oasis WAX Plus cartridges contain the Oasis WAX sorbent, which is a polymeric reversed-phase, weak anion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines. Since the Oasis WAX sorbent is water wettable, it is used to retain and release strong acids and is stable in organic solvents.
Waters Corp Sep-Pak Alumina A 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 50 - 300 µm, 10/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Certified Sep-Pak Alumina N 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 300 µm, 30/pk
Certified Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. Certified Sep-Pak Alumina N cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Oasis WAX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc Oasis WAX cartridges contain the Oasis WAX sorbent, which is a polymeric reversed-phase, weak anion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong acidic compounds. Since the Oasis WAX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading.
Waters Corp Oasis MCX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 60 µm, 100/pk
The 1 cc Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The 60 µm particle size is recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Oasis MCX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Oasis MAX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless Oasis MAX cartridges contain the Oasis MAX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting acidic compounds with anion-exchange groups. Since the Oasis MAX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Cayman Chemical MR1 ImunoaFInIty Sorbent 400uL
An inhibitor of MKNK1 and MKNK2 (IC50s 0.064 and 0.086 UM respectively) selective for MKNK1 and MKNK2 over a panel of 104 kinases at 1 UM inhibits phosphorylation of eIF4E in HeLa cells (IC50 0.321 UM) enhances dasatinib-induced tumor growth inhibition in a K562 mouse xenograft model prevents weight gain in a mouse model of high-fat diet-induced obesity at 100 mg/kg
Waters Corp Sep-Pak Accell Plus QMA 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Vac cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å). The cartridges are designed for extraction of anionic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of larger molecules such as anionic proteins such as immunoglobulins and enzymes. Other applications include isolation of phenolic compounds and removal of acidic pigments in wine, fruit juices, and food extracts. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
