Practical and easy to handle, nutrient pads reduce labor and simplify many microbiological testing procedures. They are sterile, dehydrated culture media. Once they are moistened with 3.0 – 3.5 mL of sterile and deionized (or distilled) water they are ready-to-use immediately. All Nutrient Pad Set types are supplied with the 47 mm membrane filters, with a 0.45 mm pore size, which are also individually sterile packaged.

Each NPS box contains 100 sterile Nutrient Pads, each of which is individually inserted in a petri dish and sterilized. Ten petri dishes are sealed in an aluminum bag. This special packaging in bags protects the sensitive formula constituents of the Nutrient Pad during transport and storage from fluctuations in humidity and temperature. As a result, they have a shelf life ranging from 18 to 24 months from date of manufacture.
