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.

These floating shelves look great in the bathroom and add a clean, modern touch to the space. They’re sturdy once installed and perfect for storing essentials like toilet paper, small décor, or bathroom items. Installation was straightforward, and the shelves feel secure on the wall. I really like the minimalist design and the added rail, which helps keep items in place. Overall, these shelves are both functional and stylish. Great quality and a nice upgrade for any bathroom.

Transformed My Bathroom Space—Love This Shelf!
Color: Black, Size: 23.6 inch, Color: Black, Size: 23.6 inch
Installation was straightforward, and once mounted, it feels secure. The rails on each shelf are a nice detail—they keep items from sliding off, which is especially helpful in a bathroom setting. Overall, this shelf is a great space-saving solution and adds both storage and style - plus I love the black glossy finish. Definitely recommend if you’re looking to maximize a smaller bathroom space without sacrificing aesthetics.

Love this!
Color: Black, Size: 15.7 inch, Color: Black, Size: 15.7 inch
I looked at dozens of similar shelves before settling on this one. Finally have something to fill the awkward space above the toilet. It was a little tricky to install by myself but definitely manageable. The only thing that could have made this better is if a template was included to help with making sure screw holes are level and spaced properly but it was simple enough to make one. This set was a little more than others that I looked at but I think it looks great, is solid quality. Definitely work the extra few dollars.

Great corner shelves
Color: Brown, Size: 10.5" x 10.5", Set of 4
Turned my messy bathroom into an organized display case. My bathroom was a mess with junk all over the sink area. The bottom shelves made a nice organized location for supplies, the top shelves became display shelves. Sturdy, elegant, solid.
