As a result, it guarantees the high quality of our NPS throughout their entire shelf life up to 24 months.
This special packaging in bags protects the sensitive formula constituents of the Nutrient Pad during transport and storage from fluctuations in humidity and temperature. Ten each of these petri dishes are sealed in an aluminum bag. The standard NPS box contains 100 sterile Nutrient Pads, each of which is individually inserted in a petri dish and sterilized. The level of moisture is optimal when an excess ring of water surrounding the NPS is visible. Once they are moistened with 3.0 – 3.5 ml of sterile and demineralized (or pure ) water they are ready-to-use immediately.
Nutrient Pad Sets are sterile, dehydrated culture media. Microorganisms require the appropriate culture media for optimal growth.
