Chloroform is a common laboratory reagent favored for use as a solvent due to the compounds relative unreactivity and miscibility with most organic compounds. Chloroform is a colorless, volatile chlorinated organic solvent whose vapors have a narcotic effect.
Chloroform is use as a solvent for fats, oils, rubber, alkaloids, waxes, gutta-percha, resins; as cleansing agent; in fire extinguishers to lower the freezing temperature of carbon tetrachloride. Procedures have been described for the use of chloroform in lambda plaques storage, lambda cDNA storage, the removal of mineral oil from PCR reaction samples, oligonucleotide purification, a hydroxyl radical footprinting protocol, a transcriptional run-on assay protocol, and an overlay assay for beta-galactosidase activity. It has also been used with phenol in such procedures as DNA recovery from polyacrylamide gels, ethidium bromide removal from DNA preparations, lysis protocols for plasmid DNA isolation, RNase removal, and purification of yeast DNA. A protocol describes the use of chloroform in a high-performance thin-layer chromatography protocol for sphingomyelin analysis. Chloroform can also be used in chloroform/methanol mixtures for the isolation of cardiolipids from Geobacillus stearothermophilus and their subsequent MS analysis. The isolation of the bacteriocin amylovorin L471 from Lactobacillus amylovorus DCE 471 in culture broth has been reported, using chloroform/methanol extraction and precipitation in the procedure. Chloroform/2-butanol mixtures can be used for the extraction of steroid sulfates for analysis by nanoelectrospray ionization mass spectrometry.

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 HPLC, UV/VIS spectroscopy, due to its low UV cutoff. Methanol is toxic if ingested and can result in blindness, coma and death. Suitable for LC-MS applications and spectrophotometry.

Self-contained membrane nitrogen generator produces LC/MS grade nitrogen with a maximum output pressure of 116psig and maximum flow capacity of 30L/min.

Supplier: MilliporeSigma

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.
