Paraffin wax blended with synthetic polymers, Solidification point: 56-58°C, in pastille form, Histosec® 组织学包埋剂, 含DMSO, Sigma-Aldrich®
Supplier: MERCK MILLIPORE
Histosec® pastilles is an embedding medium for histology of samples of human origin. It is a paraffin enriched with polymers, also available without the addition of DMSO (dimethyl sulfoxide). DMSO increases the rate of penetration of paraffin and provides additional preservation of the tissue structures. Its melting range is between 56 - 58 °C and, within this range any specimen can be processed without fear of damage irrespective of the method used.

溴化钾, Uvasol® 用于红外分光光度法, Supelco®
Supplier: MERCK MILLIPORE
Potassium bromide is transparent from the near UV to long wave IR wavelengths. In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analysed by grinding with potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an airtight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis.

n-Hexane, LiChrosolv® for liquid chromatography, Supelco®
Supplier: MERCK MILLIPORE
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in 'gradient grade' as well as 'isocratic grade'. This minimises the gradient effect of the solvent involved.
