The Device can be used to analyze nitrate as nitrite in physiological fluids using a single disposable microplate for both the reduction process and the Griess reaction colorimetric assay.  The Reductor has broad application in biomedical research involving in vivo nitric oxide production.

The Device also has applications in agricultural research, soil testing, and environmental monitoring.

Expensive, single-use nitrate analysis kits are replaced with a reusable device suitable for analysis of several thousand samples.

Laboratories that routinely perform ELISA testing procedures should already have the necessary equipment and supplies, and would only need to purchase the Reductor to acquire the capability to perform nitrate analysis more efficiently than with virtually any other analytical system.

Nitrate Reductor Kit includes: 1 Reductor, 1 Nunc Microplate (with 3 Locking Pins), 1 Nunc Holding Tray with Lid, 1 Cleaning Solution Container, and 3 Replacement Locking Pins. 

Uses

  • Nitrate may be successfully analyzed in virtually any sample matrix.
  • The Standard Additions Method protocol described in the cited publication, allows the relationship of water standards to statistically derived sample concentrations to be accurately established in a single operation.  An assessment of the absolute accuracy of the method for a given matrix can thus be easily determined.

Advantages

  • Expenses are reduced from several dollars per analysis when using other commercially available nitrate analysis kits to only a few cents when using the ParaTechs Reductor.
  • The need for expensive, dedicated instrumentation such as continuous-flow analyzers is eliminated.   Very little expertise, beyond accurate pipetting skills, is required to perform the analysis.
  • The Reductor has no moving parts and the analysis requires no start-up time.  The reagents are simple to prepare and are stable for extended periods.
  •  Using multiple Reductors, the daily laboratory throughput for nitrate analysis is limited only by the number of individuals applied to the task.

good for non-white skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
Moisturizing, non-sticky, works for my sensitive skin. It's transparent and doesn't leave a white cast on my light brown skin. Smallish size is good for travel and purse. It's a little shiny; wish it came in matte.

Very effective
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen for your face. It doesn’t feel oily. It doesn’t stay white on your skin. It absorbs and it really protects it nicely. I put it on every morning before I walk my dog in the sun and I’m out for normally at least an hour so it’s a really nice sunscreen and I would definitely give it a try.

Lightweight, clean, and effective — worth the repurchase
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
This is my go-to daily sunscreen. It’s lightweight, non-greasy, and absorbs quickly without leaving a white cast. I love that it’s made with clean ingredients and doesn’t irritate my sensitive skin. The white tea scent is subtle and fresh. I’ve repurchased this several times now — it’s one of the few sunscreens I actually enjoy using.

Great replacement for my discontinued Epionce sunblock
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I really hate it when companies discontinue great products, and even though it cost a fortune, I loved the Epionce mineral sun block for faces. When I realized it was gone, I looked at the Coola line because I like their other products. Found this face sunblock for $32 (this could be 1/3 of the Epionce, certainly 1/2) and have used it for the past few weeks playing golf. So far, so good! I'm not noticing any color, certainly no burn. No irritation, and the scent is quite mild, only noticeable when it's first applied (IMO, and I'm pretty sensitive to scents). I really like that Coola has the Hawaii reef-safe designation, which I think is very important for all sunscreens, even when we're not going swimming in the ocean. As a friend pointed out to me once, even if you don't swim in the ocean, you go home and take a shower and all those chemicals wash down the drain and make their way eventually through the system, so might as well just not use them in the first place! Yes, it's more expensive using products like this, but IMO it's worth it. I also wear sun sleeves these days so I don't have to use as much sunscreen when I'm out on the golf course. Editing this to say that this product has avobenzone, which is actually not so great and may be banned in Hawaii by next year. Hmm. Guess I'll keep searching!

Favorite SPF
Size: 6 Fl Oz (Pack of 2)
This is the only sunscreen my family and I use now. We’re really sensitive to heavily fragranced sunscreens, so finding one that’s fragrance-free and still works well has been important for us. I like that it sprays on easily, feels lightweight, and doesn’t leave us feeling overly greasy or sticky afterward. It’s become our go-to for beach days, travel, sports, and everyday sun protection. I also appreciate the cleaner ingredient profile and that it’s vegan and dermatologist tested. A lot of sunscreens tend to irritate my skin or give me headaches from the strong scent, but this one has worked really well for our family without those issues. Simple, effective, and one of those products we consistently repurchase year after year.
