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.

A good retelling of the highlights from the Scarlet Letter
A good retelling of the highlights from the Scarlet Letter. The art provides a good visual for a kid to reflect on after having read the story. The art for Wilson is very telling as well; he looks like the lout I always saw him as.

Not new
Format: Hardcover
There was no indication the book was used and I had to spend $37 for it, which seems outrageous.

A mom's review: They read my mind
Format: Hardcover
I was putting together broad categories for how to instruct my family of boys on aspects of the civil war. Jonathan Fetter-Vorm and Ari Kelman read my mind. From captive blacks to reconstruction and the rise of the Klan terrorists, this book does it all. I don't need to instruct - this book paints vivid pictures for my kids to absorb, relate to, and build on according to their areas of interest. My other resources come into play, but this book is the Civil War overview I had been trying to create myself. Includes disease (malaria, gangrene) and Andersonville prison, suspension of habeus corpus and desertions, Mathew Brady's photographs, hunger on the homefront, desertions, the assassination of Lincoln, more. Marvellous. I can't say enough about the quality of the graphics and narration in the book. This is graphic history as it should be done. Bravo to the authors and publishers from not shying away from the cold truths. Lincoln's presidency was ambiguous on Constitutional questions. James K. Polk was a racist SOB, like most democrats. The KKK was/is the terror arm of the democrats. Great book for Junior High and up. I can't recommend it strongly enough. You probably need one for every child in your family, because they will not want to share. More books like this, please.
