Nutrient Pad Sets

By Sartorius

Nutrient Pad Sets (NPS) are sterile, dehydrated culture media. They are composed of a sterile pad in a Petri dish which has been impregnated with dehydrated nutrient. All Nutrient Pad Sets are supplied with the appropriate membrane filters, which are also individually sterile packaged.
Once they are moistened with 3.0 – 3.5 ml of sterile and demineralized (or destilled) water they are ready-to-use immediately. The level of moisture is optimal when an excess ring of water surrounding the NPS is visible.
Sartorius Nutrient Pad Sets have been used successfully in the membrane filter method for more than 20 years. The membrane filter method allows large sample volumes with low microbial count to be tested. Inhibitors, such as essential oils or disinfectants, can be rinsed out after filtration, before incubation.

NPS are practical and easy to handle, Nutrient Pad Sets reduce labor and simplify many microbiological testing procedures. The standard NPS box contains 100 sterile Nutrient Pads, with each ten NPS sealed in an aluminum bag. This special packaging protects the sensitive formula constituents of the Nutrient Pad during transport and storage from fluctuations in humidity and temperature. As a result, it guarantees the high quality of our NPS throughout their entire shelf life ranging from 18 to 24 months. NPS do not require refrigeration.
