The CP-Wax™ lines of chemically bonded columns offer a broad range of selectivities for method optimisation. The backbone of this series stationary phases is made of a polyethylene glycol.

Supplier: VARIAN

The Vac Elut™ 20 vacuum control valve, vacuum gauge, and quick release valve are mounted on the lid, away from the corrosive waste stream and within convenient reach. The solvent-resistant PP rack is available in a variety of sizes to accommodate collection tubes commonly used in sample preparation.

Supplier: VARIAN

The Vac Elut™ 20 with a large glass basin and collection rack accommodates larger 16×150 mm test tubes. The same high quality material and features on the standard Vac Elut™ system are incorporated on this special unit. These collection vessels can be utilised in combinatorial chemistry applications using large boiling tubes for collection of purified synthesis mixtures, or for any SPE extraction in which an elution volume greater than 10 ml is required.

Solid Phase Extraction (SPE) plate, 96-round well plate, Bond Elut™, Polymeric sorbents, Plexa, 30 mg

Supplier: VARIAN

The PLRP-S family of products consists of a range of pore sizes and particle sizes, all with identical chemistry and fundamental adsorptive characteristics. The particles are inherently hydrophobic so there is no bonded phase, alkyl ligand required for reversed-phase separations. This gives a highly reproducible material that is free from silanols and heavy metal ions. Within the extensive product range are columns suitable for analytical separations and preparative purifications.

Supplier: VARIAN

Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Supplier: VARIAN

The quickest and most convenient method to deliver an accurate 12 point column calibration for organic and aqueous GPC/SEC column calibration.

Supplier: VARIAN

These PL aquagel-OH™ analytical coluns have a highly stable matrix ensuring reliable separations, even with modified eluents.

Supplier: VARIAN

Faster than centrifugation and easily automated, Captiva's dual depth filtration media provide complete removal of precipitated proteins and outstanding resistance to sample clogging. The plates are also excellent for sample storage. All Captiva components are ultra clean, and rigorously tested to ensure against non specific binding.

Supplier: VARIAN

Seal kits are available in various capacity based on the pump head sizes.

Supplier: VARIAN

Though highly stabilised, it is impossible to guarantee that no particles will dislodge from the column wall. When used in valve-switching applications, the use of a particle trap can prevent scarring of the rotors.

Supplier: VARIAN

Florisil is a magnesia-loaded silica gel, extremely polar in nature and ideal for the isolation of polar compounds from non-polar matrices.

Supplier: VARIAN

The PLRP-S reversed phase HPLC media delivers the pure oligonucleotides (oligos) required for genomics applications, including quantitative PCR, microarrays, and gene synthesis assays.

Supplier: VARIAN

Strongly basic anion exchanger, Cl⁻ form. Moist, light yellow spherules.

Supplier: VARIAN

Bond Elut™ SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut™ PRS, the presence of the benzene ring in the functional group increases the potential for non-polar interactions. This non-polar characteristic becomes particularly important when conducting ion-exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and non-polar character is seen.

Supplier: VARIAN

Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.

Supplier: VARIAN

CP-Sil 43 CB separates aromatic from aliphatic hydrocarbons with moderate polarity for specific selectivity equivalent to OV-255.

Supplier: VARIAN

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