VISOCOLOR ECO – Kit für kolorimetrische und Titrationstests

Der VISOCOLOR ECO-Test ist ein kolorimetrisches und titrimetrisches Testkit, mit dem sich untere Grenzwerte präzise bestimmen lassen. Durch die präzise Dosierung der einzelnen Reagenzien und die Möglichkeit, Trübungen und Verfärbungen zu kompensieren, wird ein hohes Maß an Genauigkeit und Empfindlichkeit erreicht.

Die visuelle Auswertung kolorimetrischer Tests erfolgt anhand hochwertiger Farbkarten, die der Originalfarbe der Standardlösung entsprechen. Darüber hinaus können die meisten VISOCOLOR ECO-Tests mit den Kompaktphotometern PF-12Plus und PF-3 photometrisch ausgewertet werden, sodass eine feinstufige Auswertung der Tests möglich ist. Für die photometrische Auswertung und als Ersatz für verbrauchte Reagenzien sind kostengünstige Nachfüllpackungen erhältlich.

Alle VISOCOLOR ECO Testkits sind in einer praktischen Kartonverpackung und mit einer leicht verständlichen Bedienungsanleitung ausgestattet. Zusätzlich stehen zu allen Prüfsätzen praktische Piktogramm-Abbildungen zum kostenlosen Download zur Verfügung.

Great mineral sunscreen
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
Great mineral sunscreen, rubs in well, protects well during high UV times, doesn't sweat off, not strong smell. Used this for fist time on a 95% high humidifier day while walking around Pittsburgh between 11am-3pm. No burning at all. There is a film left but that's for almost all sunscreen, so not any difference with this one. Easy to rub in and may leave a slight white coat but not as noticeable as some other mineral products. I will buy this again and recommend.

One of the bests
I’m a full time trucker and I wear sunscreen everyday. In my opinion, this is the best sunscreen out there. It feels like makeup primer on skin, it dries clear. The white cast has always been a turn off for me looking like a geisha to work or the white cast residue on the collar was icky. Although this feels oily and shiny a bit glass skin but not sticky just powdery feel. I recommend it 👍🏻

GREAT COVERAGE!
Even, protective coverage. Great SPF to keep you safe from damaging UV! I apply evenly over face, let set, then I can put my makeup on.

Not for oily skin
Not the best for oily skin. No matter how little I put on, it feels greasy and makes me look so shiny. This is even after I put on sunscreen setting powder. I’ll keep it and use it for days I’m not in the sun much. The days I am outside a lot, I will have to stick to my black girl matte sunscreen.
