Proveedor: Thermo Fisher Scientific

Descripción: A polar sorbent for both polar and anion exchange interactions.

Proveedor: VARIAN

Descripción: Bond Elut empty SPE cartridges are made with high purity polypropylene for cleaner extracts.

Proveedor: VACUUBRAND

Descripción: Vacuum filtration is one of the most common applications used for sample preparation in chemistry, microbiology, wastewater control and other analytical processes. VP 100 and VP 100 C diaphragm pumps offer a compact, high performance and easy to use solution which is perfect for both single and multiple filtrations.

Proveedor: Thermo Fisher Scientific

Descripción: Strong anion exchange sorbent for extraction of weak acids.

Proveedor: Thermo Fisher Scientific

Descripción: A strong cation exchange sorbent for extraction of charged basic compounds.

Proveedor: Restek

Descripción: These cartridges are made of glass fiber disks embedded with C18 or C8 bonded silica. These hydrophobic (nonpolar) silica-based adsorbents are ideal to extract hydrophobic analytes from polar matrices, such as water (e.g., pesticides from water).

Proveedor: Thermo Fisher Scientific

Descripción: A short alkyl chains with polar functional groups are ideal for the isolation of polar compounds.

Proveedor: Thermo Fisher Scientific

Descripción: HyperSep™ C8 cartridges, less retentive alternative to C18 for polar and nonpolar compounds.

Proveedor: Restek

Descripción: Cartridges have been specifically designed to provide consistent and reproducible results for the method or application stated.

Proveedor: Restek

Descripción: Resprep tubes, frits, caps, and connectors for method development needs.

Proveedor: Restek

Descripción: CarboPrep® cartridges are manufactured from chromatographic-grade, nonporous, graphitized carbon. Our manufacturing process minimises variability and improves recovery and cleanup procedures.

Proveedor: VARIAN

Descripción: Bond Elut AccuCAT cartridges are mixed bed SPE cartridges consisting of a strong cation exchange (SCX) and a strong anion exchange (SAX) sorbent packed into one bed. AccuCAT is effective for the extraction of acidic, basic and neutral analytes from urine and other biological samples. AccuCAT is particularly effective for catecholamine extraction from bio fluids.

Proveedor: VARIAN

Descripción: Bond Elut™ C18 OH is a non-end capped version of the octadecyl bonded phases that enables the silanols on the silica surface to be more active. This low-load C18 has well-controlled silanol activity that permits the fractionation of metabolites and enhances retention of basic compounds compared to an endcapped C18. The pore size makes it a good choice for peptide extraction.

Proveedor: Thermo Fisher Scientific

Descripción: These columns feature a highly retentive alkyl-bonded phase for non polar to moderately polar compounds.

Proveedor: Restek

Descripción: These cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts).

Proveedor: VARIAN

Descripción: Bond Elut™ SAX is a strong anion exchange sorbent ideally suited for the extraction of compounds such as carboxylic acids, which may not retain effectively on weak anion exchange sorbents. The sorbent is supplied in the chloride counter ion form. You can modify the selectivity of the phase by replacing the chloride ion with other anions, such as acetate and hydroxide.
