Azide Nutrient Pad Sets for Enterococci, 100 NPS in petri dishes, with 100 sterile membranes
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.
Trouble-free storage up to 24 month
Compliance with international standards and references
Validation guide available
Highly versatile -multiple applications
Economical – no time consuming and labor intensive preparation of nutrient media (sterilization, cleaning etc.)
Easy handling – no need for comprehensive microbiological testing equipment

Chemical Guys Leather Quick Detailer for Car Interiors 32oz
Size: 32 Fl Oz (Pack of 1)
Reliable Quick Cleaner for Leather Interiors I’ve been using the Chemical Guys Leather Quick Detailer on my car’s interior for a while now, and it’s become one of those go-to products I like to keep on hand. As the name suggests, this is designed for quick touch-ups rather than deep cleaning, and for that purpose, it really does the job well. The first thing I noticed is how easy it is to use. A couple of sprays on the leather seats or steering wheel, a quick wipe with a microfiber cloth, and the surface instantly looks cleaner. It removes light dust, dirt, and fingerprints in seconds. Unlike some products I’ve tried in the past, it doesn’t leave behind a slick or greasy feel, which is important when you’re dealing with things like a steering wheel or gear shifter that you’re constantly touching. Instead, the finish is clean, soft, and natural-looking, which is exactly what I want. The scent is another plus. It has a pleasant, subtle leather fragrance that makes the car smell fresh without being overwhelming or chemical-like. I don’t like products that leave behind a strong odor, and this one strikes the right balance. Another strength is its versatility. While it’s marketed as a car interior detailer, I’ve found it works well on other small leather items, like a laptop bag or even a chair at home. Obviously, it’s not a replacement for a full leather conditioner, but for light upkeep it’s nice to have a single product that can handle more than just my car. That said, there are a few things that keep this from being a perfect 5-star product. First, it’s definitely not designed for deep cleaning—if your leather is heavily soiled, stained, or dried out, this won’t be enough. You’d need a dedicated cleaner and conditioner for a full restoration. Second, the spray nozzle can be a bit inconsistent, sometimes giving off more of a stream than a fine mist. It’s not a huge issue, but it can waste product or make application less even if you’re not careful. Lastly, while it makes leather look clean and refreshed, it doesn’t provide as much conditioning as some other products, so if you’re looking for something that really nourishes and protects long term, this is more of a maintenance step than a solution. Overall, though, I’m very satisfied. The Chemical Guys Leather Quick Detailer is perfect for keeping leather looking sharp between major cleanings. It’s fast, effective, and leaves behind a clean finish without unwanted residue. It saves me time and keeps my car interior looking well cared for, which is exactly what I want from a quick detailer. I’d rate it 4 stars—an excellent product for regular maintenance and touch-ups, with just a few small shortcomings that prevent it from being the ultimate all-in-one leather care solution.

Great leather cleaner
Size: 16 Fl Oz (Pack of 1)
Bought this because I accidentally got some sunscreen stains on my leather interior in my car. Just a quick spray of this and a wipe with a microfiber towel and the stains are gone! Very pleased with the product and would definitely recommend to anyone who is looking for a nice leather cleaner!

Works as advertised and smells good
Size: 16 Fl Oz (Pack of 1)
My daughter and I went to the beach. She didn't put her cover up back on and got sunscreen on the black leather seats. This stuff worked great. Cleaned it off and hopefully protects for anything else headed towards my seats in the future.

This will melt built up dirt in no time.
Size: 16 Fl Oz (Pack of 1)
I bought a 3 bottle set that included the interior cleaner, cloth cleaner and leather cleaner. All three worked really well when I used them. The cloth cleaner lifted and disolved the surface dirt from the the seats and made easier to use a portable wet vac to vacuum the dirt. The interior cleaner did a far superior job on melting built up dirt on the seats, dashboard, steering wheel and other surfaces. The leather cleaner did pretty much the same as the other two and I can see myself buying this again. It dried quickly too
