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.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.
