Sartorius Nutrient Pad Sets have been used successfully in the membrane filter method for more than 30 years. Practical and easy to handle, Nutrient Pads reduce labor and simplify many microbiological testing procedures. Microorganisms require the appropriate culture media for optimal growth. Nutrient Pad Sets are sterile, dehydrated culture media. Once they are moistened with 3.0 – 3.5 ml of sterile and demineralized (or pure ) water they are ready-to-use immediately. The level of moisture is optimal when an excess ring of water surrounding the NPS is visible.

The standard NPS box contains 100 sterile Nutrient Pads, each of which is individually inserted in a petri dish and sterilized. Ten each of these 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, it guarantees the high quality of our NPS throughout their entire shelf life up to 24 months. This makes the Sartorius Nutrient Pads Sets unique: No other ready-to-use culture media around the globe assures such consistently high quality and reproducible results up to 24 months.

Compliance with International Standards: Currently, Sartorius offers more than 30 different Nutrient Pad Set types to meet the diverse requirements of microbiological analysis. Aside from the European drinking water directive, they comply with other international regulations and recommendations: international pharmacopoeias, DIN and ISO standards, the American Standards for Water and Foods, mineral water regulations, brewery guidelines, such as MEBAC or EBC, and recommendations of the food industry, such as LMBG, NCA and ICUMSA, etc.

Includes Membrane Filters: All Nutrient Pad Set types are supplied with the appropriate membrane filters, which are also individually sterile packaged. Nutrient Pad Sets are also available with Microsart® e.motion Membrane Filters which are specially designed for the Microsart® e.motion Dispenser and can be conveniently inserted. The membrane filters are then automatically removed from their sterile package.

Not durable
Color: red
Although it holds about two cups of food or treats, my 40lb dog can bite down hard enough that you can no longer move the dispenser hole. It entertains her for hours but it could be a bit more durable for larger dogs or specify that it is for smaller pups

Durable and Resilient
Color: yellow/orange
I fill the dispenser with their normal Kibble food. It's my slow feeder and herding toy. Every morning the Mini Aussies look forward to taking turns pushing this dispenser around as the Kibble falls out. They never miss a Kibble! Often times they push it so hard it hits the kitchen cabinets and literally flys airborne dropping Kibble! This is extremely durable and resilient. Rarely needs to be washed. Easily hand wash when needed. Highly recommend. This is my 2d one purchased. The first one still works but after about one year of use I noticed the plastic thread to screw on top has been damaged. It still works but want to be prepared if it cannot be used safely anymore. Enjoy! The Aussies sure do!

Toy for Pup
Color: yellow/orange
The only toy that my dog will play with. It helps keep him busy while I'm cleaning. It is suitable for small dogs and safe for them. He twists and turns it around but the toy is still in good condition so the quality is great.
