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.

You get what you pay for
Style: Steam Mop
It's just OK. It does get the job done, but poorly made and I don't expect it to last long. Unlike other steam mops I've had, this one leaves the floor wet. Plus the pad does not pick up any stuck-on gunk that the steam loosened. I had to go back and pick up a few pieces by hand. Instructions say to let the water tank air dry before storing, but the attached lid makes it hard to let air into the tank. In retrospect I should have spent a few dollars more and gotten a better unit.

Good purchase for the price point
Style: Steam Mop
This mop is perfect as it is compact while being easy to use. Stuck food on the floor? Not after using this. Crayon? Vanishes. Sticky substance? no more. Great but for the price

It is a keeper for sure!
Style: Steam Mop
This is about 100% better than I ever imagined. It has every feature I want and none of the stuff I don't want. It has a SUPER long cord, it heats up quick and works exactly as it is supposed to. I steam cleaned everything from my stained concrete floors, THE ENTIRE COUCH, and low pile area rugs. Love this thing and SO MUCH cheaper that the competing brands.

Great Starter Knife Set With Everything You Need
Size: 9-Piece, Style: Traditional Handle Design
5/5 stars for the Amazon Basics High Carbon Stainless Steel Knife Set. I have been really impressed with this set overall and it has handled pretty much every kitchen task I have thrown at it so far. Right out of the box the knives were insanely sharp and felt much higher quality than I was expecting for the price. One of the biggest pros is the variety of knives included. It comes with basically every knife you would need for normal cooking and kitchen use which makes it a great all-in-one set. The knives also have a really nice weight to them and feel balanced in the hand instead of feeling cheap or flimsy. The grip is nice as well not slippery and while using it I feel like it stays put in my hand. They have held up well with regular use and have been easy to clean after cooking. The high carbon stainless steel has also done a good job resisting rust and staining which is important for a set that gets used often. Another nice addition is the included honing rod which helps maintain the edge and keep the blades performing well over time. I did notice that the edge on the knife I use the most has started to wear down a tiny bit after extended use, but that is expected with pretty much any frequently used kitchen knife and can usually be maintained with regular honing. As for cons, the wooden knife block is nice looking but I could see it potentially cracking over time if it is not taken care of properly or exposed to too much moisture. Other than that, I really do not have many complaints with this set. Overall I think this is a fantastic knife set for anyone who just moved out and needs a complete kitchen setup or for someone wanting to replace an older worn out knife set. I actually gifted a set to my in-laws already and they have been loving it as well. I would definitely recommend it.
