"HPLC Solvents"

Supplier: MERCK, S.A. DE C.V. SV

Offering a high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. Since separations are normally carried out under gradient conditions in analytical HPLC, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.

Methanol (CH₃OH) is also known as Methyl Alcohol or wood alcohol. It is a clear, colorless, volatile and flammable liquid. Methanol is a common laboratory solvent and is especially useful for chromatography due to its low UV cutoff. Methanol is toxic if ingested and can result in blindness, coma and death. Suitable for HPLC and spectrophotometry.

Supplier: Cytiva

Suitable for use in a wide range of specialized applications, including HPLC mobile phase filtration and degassing, bacterial analysis by epifluorescent light microscopy, ultra cleaning of solvents, gravimetric analysis, and liposome extrusion.

These mobile phase delivery bottles are a low cost option for solvent bottles made from Type-33 borosilicate glass.

Supplier: DWK LIFE SCIENCES S. DE R.L. DE MX

Designed for preparation, storage and delivery of all liquid chromatography mobile phases. As part of our ULTRA-WARE® series, these reservoirs are recommended for use under vacuum for filtration and vacuum degassing of mobile phase solvents.

Supplier: RESTEK CORP

General-purpose columns for solvents, Freon® fluorocarbons, alcohols, ketones, silanes, and glycols.

Supplier: Cytiva

Useful for a wide range of both aqueous and solvent-based applications. Hydrophilic nylon filters offer excellent chemical compatibility with esters, bases, and alcohols. Not recommended for acids >1N or halogenated solvents.

PVDF (polyvinylidene difluoride) is a hydrophilic, solvent-resistant membrane with low levels of UV absorbing extractables. Housing manufactured from medical grade, virgin polypropylene. Low nonspecific binding. Use for HPLC sample filtration and general biological filtration. PVDF is also a low protein binding membrane. Enhanced female Luer-lock inlet; male Luer slip outlet. The 4mm filters can be used for volumes less than 2mL. The 0.2µm pore size filter can be used for “cold” sterilization.

Supplier: SOLSTICE ADVANCED MATERIALS US FOR

For HPLC, GC, pesticide residue analysis, and spectrophotometry. UV cutoff at 200nm.

Supplier: SOLSTICE ADVANCED MATERIALS US FOR

Clear, colorless liquid. For specialty organic synthesis, preparative scale HPLC, and glassware cleaning. The 54gal. drum is individually analyzed with certificate on label.

Whatman Puradisc H-PTFE syringe filter contains a hydrophilic membrane that is chemically stable and inert. The H-PTFE membrane exhibits low protein binding and can be used for both aqueous and aggressive organic solvents.

Supplier: Corning

For filtration of liquids from 0.5mL–100mL. Available in 4, 15, 25, 26, and 50mm diameter filters. Available in polyethersulfone and surfactant-free cellulose acetate for cell culture applications requiring low protein binding, and in fluoropolymer resin PTFE resin, regenerated cellulose, and nylon for HPLC applications requiring a broad range of chemical compatibility. Redesigned 26mm filter increases effective filtration area resulting in faster flow rates and higher throughput. 50mm fluoropolymer resin vent filters help prevent aggressive solvents from damaging vacuum lines and pumps.

Supplier: RESTEK CORP

General-purpose columns for the analysis of FAMEs, flavor compounds, essential oils, amines, solvents, and xylene isomers.

Supplier: Cytiva

These syringe filters offer a choice of filter media: hydrophobic PTFE membrane for exceptional chemical and temperature compatibility; hydrophilic nylon membrane for excellent chemical compatibility with esters, bases, and alcohols, without prewetting; GHP (hydrophilic polypropylene) membrane for low protein binding; and hydrophilic PVDF (polyvinylidine fluoride) membrane for use in aqueous and nonaggressive, solvent-based mobile phases. Polypropylene housing with female Luer-lock inlet and standard male slip Luer outlet connections. All membranes are HPLC certified for low levels of UV-absorbing extractables.

Supplier: Cytiva

For prefiltering heavily contaminated aqueous or solvent based samples. Filters are made of 100% binder-free borosilicate glass fiber. Hydrophilic nylon membrane has excellent chemical compatibility with esters, bases, and alcohols and does not require prewetting. GHP (hydrophilic polypropylene) membrane is low protein binding. Both nylon and GHP membrane filters include a glass fiber prefilter layer, as well as being HPLC certified for low UV-absorbing extractables. The regular glass fiber membrane has very low extractables. Polypropylene housing. Female Luer-lock inlet and male slip Luer outlet.
