Sartorius® Chromocult* NKS and emotion MF, 0.45 µm, NKS for Microsart e.motion

Sartorius nutrient carton discs, or NKS for short, have been used successfully in conjunction with the membrane filter method for 20 years. The membrane filtration method enables the quantitative determination of microorganisms in relatively large sample volumes. Inhibitors, such as essential oils or preservatives, can be rinsed out without difficulty prior to incubation.Nutrient carton discs facilitate and simplify many microbiological test procedures due to their practical handling. Microorganisms require the appropriate nutrient medium in order to grow optimally.NKS are sterile nutrient media in dry form, already placed in sterile Petri dishes. After moistening with 3.0-3.5 ml of sterile distilled or demineralized water, the NKS are immediately ready for use. Moistening is ideal when a clear excess of liquid is visible at the edge zone.All NKS types are supplied with the appropriate membrane filters, which are also individually and sterilely packaged. The membrane filters, which were specially developed for the special requirements of germ detection, are available in either 50 mm or 47 mm diameter.The nutrient carton discs (NKS) are constantly being improved as part of our product development to meet the changing requirements of the application. Apart from new NKS types, we have also optimized the packaging design. The standard pack of nutrient carton discs contains 100 NKS, each individually placed in a Petri dish and sterilized. Ten of these Petri dishes are each sealed in an aluminum bag. This specially designed packaging protects the sensitive components of the nutrient medium from changes in humidity and temperature fluctuations during transport and storage. Thus, we can guarantee the high quality of the nutrient carton discs during the entire shelf life of up to 24 months. And this is exactly what makes NKS so unique: no other ready-to-use culture medium in the world ensures reproducible results for up to 2 years with consistently high quality. Sartorius currently offers more than 30 different NKS types for different test objectives. In addition to drinking water guidelines, other international regulations are also met: international pharmacopoeias, DIN and ISO standards, American Standards for Water and Food, mineral water regulations, brewery guidelines such as MEBAC or EBC, food industry recommendations such as LMBG, NCA and ICUMSA, etc. Problem-free storage of up to 24 months Economical due to time and cost savings In accordance with international standards and references Easy handling Validation documents available Consistent quality Versatile NPS SEARCH The NPS'' SEARCH provides access to all nutrient carton disc information quickly and easily. With this application guide you will surely find the optimal NKS type for your application.
