Endo Nutrient Pad Sets for E. coli and coliforms, 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

Great for Sensitive Skin
Color: Non-Tinted, Size: 1.7 Fl Oz (Pack of 1)
My face has always been sensitive to sunscreens, so I have to be careful with what I use on my face. (Others can cause burning sensations). This sunscreen is great. I had no issues, and unlike other sunscreens, sweat running didn't cause my eyes to burn or water which was great. Keeps my skin protected against the hot Florida sun, so it works!

And the crowd goes mild
Color: Tinted, Size: 1.7 Fl Oz (Pack of 1)
I had heard such great things but I’m really left a little disappointed. I got the light tinted version, and it’s much darker than anticipated. And the smell is not great. It kind of smells like my grandpa’s trailer and not in a nice, nostalgic way. As a sunscreen though, I have no complaints. The protection is great and at the end of the day that’s what I really need out of this.

Gentle but effective
Size: 4 Fl Oz
I’ve used quite a few exfoliating products over the years, but I keep coming back to this one because blackheads seem determined to make themselves at home in my pores. No matter how consistent I am with the rest of my skincare routine, they always find a way to show up, especially around my nose and chin. What I like most about this exfoliant is that it works without feeling harsh. It has a lightweight liquid texture that applies easily and absorbs quickly. Unlike physical scrubs that can leave my skin feeling irritated or over-exfoliated, this provides gentle chemical exfoliation with none of the rough scrubbing. My skin feels smoother after use, and I don’t get the tight, stripped feeling that some acne-focused products can cause. After using it regularly, I notice fewer clogged pores and a visible reduction in blackheads. My pores also look less noticeable, and my skin texture appears more even overall. It helps keep congestion under control before it turns into larger blemishes, which is a big reason why it has remained a staple in my routine. For me, this is one of those rare products that manages to be both effective and gentle at the same time. If blackheads and clogged pores are an ongoing battle, this has been one of the most reliable products I’ve found for keeping them under control while still being comfortable enough for regular use. Summary: This exfoliant has earned a permanent spot in my skincare routine. It helps reduce blackheads, keeps my pores looking clearer, and improves overall skin texture without irritating my skin. For anyone dealing with persistent pore congestion, it’s easy to see why this product has such a loyal following.

If you actually understand how to use it, it's amazing.
Size: 4 Fl Oz
My skin type: - Very Dry, easily dehydrated - Oily nose - Prone to stubborn acne and closed comedones - Redness on chin and cheeks (not rosacea) I already use a nightly Tretinoin cream (.04% concentration) to help with my acne and premature signs of aging but decided with my derm that incorporating a BHA would be a good idea to help with my seriously stubborn closed comedones and some irritating textural issues. It was between this and the Cerave SA lotion and I ultimately decided on this due to the higher concentration of salicylic acid. It's moisturizing, and feels sticky for the first 5-10 minutes after application but seems to sinks in to something of a satin finish on me and I can no longer feel it on my skin. You just have to be a little patient. My skin feels well hydrated and plump after it settles and looks really smooth and my pores aren't as obvious. It sits just fine under makeup for me but I'm not a new user to chemical exfoliants so I don't have lots of dead skin pilling up or sloughing off when I use it, my skin is, for the most part, already very smooth outside the acne and CCs. Occasionally I'll apply it further down my neck/decolletage than usual and WOW do I old skin just ball up and peel right away - it's so gross but also satisfying. So those that don't exfoliate often or are new to BHA/AHAs will likely have issues with foundation until their skin adjusts (but it will adjust). My advice in those cases is to either use this at night for the first few weeks or just accept going barefaced for a little while if you can. I'd strongly suggest not applying this product over anything that you feel does not dry down fully, the times I've attempted to use it after serums or heavier products it takes forever to sink in and sometimes never fully does. I save all my serums and essences for after this has absorbed and it's far easier to work with it as a result. My steps go like this most days: ACWell Licorice toner --- PC 2% BHA --- 10% Niacinamide serum --- TO Matryxil serum --- Secret Key Black Snail cream or Syn-ake cream w/ 3 drops Stratia Fortify oil --- Sunscreen. It works fairly quickly IMO, on my neck where I typically don't apply my Tret at night I noticed the peeling and balling of dead skin on day one and on my face where I have a patch of really awful CCs I noticed them getting smaller and smoother by around day 3-4. I'm going on about 8 days now and they're barely visible unless I'm right up in the mirror and feel as if they're almost gone when I touch my fingers to that area. I do have some slight peeling of the skin around my mouth and nose but it's not terrible (likely because I already exfoliate the heck out of my skin with the tret). Some tips and things keep in mind: 1) DO NOT RINSE IT OFF. I don't understand some of the top reviews advising people to do that, it says on the bottle not to rinse and nearly all chemical exfoliators are meant to be left on until the next cleansing specifically so they can do their job. If you rinse it off you're either going to prevent it from properly exfoliating or end up irritating the hell out of your skin. If you have oily skin and feel this might be heavy on you than you can probably just use this on bare skin and then sunscreen if you use in the AM or a lightweight lotion/cream and be done with it, but you need to leave it on your skin. 2) You have got to use sunscreen while you're using this product! Any BHA or AHA exfoliant causes increased sun sensitivity and you have to address that in your routine. You should already use sunscreen daily but it becomes a must when you incorporate a chemical exfoliator or you risk sun damage. 3) Less is more! Don't slop this on your face or soak a cotton pad in it, a little goes a long way and you'll be kicking yourself if you apply way too much and have to wait 20+ minutes for it to sink in. Use a shake or two and add more if needed but go easy. 4) Expect some irritation initially. Chemical exfoliants can be harsh and rough even on sturdy skin and you have to give yourself time to adjust. Over-exfoliation is a possibility but sometimes just introducing a BHA or AHA into your routine can cause some sensitivity. Don't panic and just be gentle to your skin. Use ceramides (like Cerave Skin Renewing cream) or fatty oils to soothe your face if needed and try to stay away from any harsh products or acids like Vitamin C right after applying this to avoid really burning your face.

Amazing exfoliating toner
Size: 4 Fl Oz
I am almost 40 and have had acne since puberty. I have tried so many products. The products that showed some improvement (like Proactiv) changed the texture of my face. Literally made my face feel like a basketball. I’ve tried some products that I’ll notice an improvement after a week or so, and the it would just stop working. I have never used something that so drastically helped my face in such a short amount of time. Notably, within 5 days my blemishes were almost gone. Within a week, my chin felt smooth instead of feeling the bumps of every clogged pore. The discoloration of my face, such as the redness, hasn’t totally disappeared, but it is improving. My face doesn’t feel oily throughout the day. My skin feels tighter, like I got a facelift. Moisturizer along with this product is important. And it is important to follow the directions and start slowly with this product. Use it every other day for the first week, gradually working your way up to daily and then twice a day. It is a shock to your skin and can dry it out if you go overboard. But for what I needed this product for, it has exceeded my expectations in every way. I couldn’t recommend it more. Just a heads up, it is applied like a toner. I expected a face wash, but it is a liquid that you apply to cotton and rub on your face. I wash with CeraVe SA cleanser, follow it with this, and apply whatever moisturizer you prefer—I’ve been using moisturizer with SPF so as to not damage my skin more than I already have.
