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. All membrane filters, tailored to meet the special requirements of microbial detection, are available with 47 or 50 mm diameter.

Great quality natural brushes to replace plastic
Been swapping out all the plastic junk for natural items. These brushes are great, I use them with dish butter and they work great. So far holding up really well. Plenty of brushes for different needs, we even have a dedicated veggie scrubber now.

Not Bad
This is how the item arrived. The bristles may be a little rough, but if you are expecting this organic alternative to resemble the same convenient quality as plastic or a sponge… I don’t know what to tell you.

Great Set of Brushes for Variety of Needs
Excellent set! Very pleased! You even get an extra head with the dish brush. Sooo much better than plastic imitations! The smaller dark bristled brush is pretty stiff, not sure I would use in my job stick pans, but makes a great veggie cleaning brush! Between variety of brushes, you can reach very thing in variety of situations and shapes! Absolutely love them!

Moldy bristles in less than two weeks.
Mold. Less than two weeks of use and mold. Ew. The wood does not seem like it's properly sealed for a product that is expected to be used with water. I threw them away. Not even worth trying to return as it didn't feel hygienic.
