2018年10月31日 · DMSO is a very good solvent for solubility (is dissolves almost everything) but poor choice due to long UV cut-off wavelength and presence of fluoresence impurity. Here is a list of solvent and...

UV-Vis spectroscopy studies of the interactions between the compound and calf thymus DNA (CT-DNA) showed that the compound interacts with CT-DNA via intercalative binding. The colorimetric...

Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol<TMSYMBOL></TMSYMBOL> solvents range has been specially designed for spectroscopy and other …

UV-Vis absorption spectrum of free primuletin in DMSO ( Figure 3 and Table 2) displays two defined bands at 273 nm and 337 nm and a shoulder around 300 nm. By comparison with the literature of...

1、DMSO在低波段有较强的紫外吸收，你的杂峰是不是出在190-270nm之间？ 还有就是当DMSO本身纯度不好的时候，可能干扰更明显，色谱级别好点。 2、推荐其他在210-400nm无紫外吸收的溶剂。

2010年8月13日 · dmso紫外吸收的问题，今天测了dmso的紫外吸收，以甲醇为溶剂，较高浓度时吸收带很宽，200-235均有，多次稀释后出现209有吸收峰，请问，209能算做是dmso的吸收吗？

Freezing of cells for cell culture :Dimethyl sulfoxide (DMSO) is widely used for the freezing of cells in cell culture instead of glycerol. DMSO is added to prevent the formation of ice crystals during the freezing process, otherwise cells would be destroyed. DMSO is commonly used at the concentration of 10%. Please note: DMSO is toxic to cells!

This page provides supplementary chemical data on dimethyl sulfoxide. The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet (MSDS) for this chemical from a reliable source such as SIRI, and follow its directions. 291.67 K (18.52 °C), ? Pa.

Record the UV absorption spectrum between 270 and 350 nm in a 1-cm cell, using water as the blank: the spectrum is smooth with no absorption maxima; the absorbance at 275 nm is not more than 0.20, and the absorbance ratios, A285 / A275 and A295 / A275, at the wavelengths indicated by the subscripts, are not more than 0.65 and 0.45, respectively.

2004年5月1日 · In order to accomplish this, we measured the concentration time-profiles of DMSO and its degradation intermediates during the UV/H 2 O 2 treatment. In addition, we proposed a kinetic model that could account for the degradation pathways of DMSO during its UV/H 2 O 2 treatment.
