Dip slides for surfaces and in liquids, Envirocheck®

目录号: (MERC1.02149.0001)

供应商: MERCK MILLIPORE

描述: Envirocheck® contact slides are widely used to check critical control points (CCP's) within the HACCP (Hazardous Analysis Critical Control Point) for the microbiological hygiene control of surfaces in production lines and equipment. Additionally these slides can be used to check the microbiological hygiene status of liquids. The use of a variety of media on the contact slides allows the detection of organisms from liquids as well as surfaces. These slides provide semi-quantitative results for five different parameters. Easy incubation in the Cultura® mini incubator also reduces the necessary workspace. Each contact slide is packed in a PC tube, which protects the agar media against contamination before and after sampling.

E/E ≥99.9% (by GC), LiChrosolv®, gradient grade for liquid chromatography, Supelco®

供应商: MERCK MILLIPORE

描述: 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.
