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.

Yes, Black Cowboys in NYC!
Format: Hardcover
I just read this book with my granddaughter on Libby and ordered it immediately from Amazon. (I will also order it in a Spanish version for my granddaughter to bring to her school). My husband is a musician who performed at the “Atlantic Antic” in Brooklyn many, many years ago. He told us about the Black Cowboys in Brooklyn who trotted up to his concert on Atlantic Ave. “It was surreal,” he said, “to see black cowboys on horseback in New York City!”

thrilling ride of a book
Format: Kindle
Beautiful... I love the tenderness of the father-daughter relationship, and the gentle love between rider and horse, contrasted with the raw thrill of the pre-dawn adventure. This book manages to portray something so specific - an urban horseback ride - with such deep and universal appeal.

Beautiful book!
Format: Hardcover, Format: Hardcover
This book perfectly exemplifies how soft and simple can be so magical. The lyrical language laden with sensory details, paired with the vibrant visuals, makes for an absolute treat of an experience! The father-child time at night immediately reminded me of OWL MOON and just like owling, urban horseback riding is something we’ve never experienced personally, so it was especially thrilling to experience it with my children through this book. I also love that this book is a celebration of Black culture and joy. Finding the universal through the specific is the key to any good story, and the author has a real knack for it. Just like the Abuelita in this story, my mother is the first to wake up, and we find her nestled in her chair with a cup of coffee. And the description of the little girl’s kiss on her Abuelita’s papery cheek brought back memories of my own grandmother’s papery cheek – something I miss very much. Picture books really are for everyone. All the starred reviews are so well-deserved and I’d be very surprised if this book didn’t win awards. Highly recommend!

Gorgeous, joyful, and moving
Format: Hardcover
This book is simply breathtaking, from the vibrant illustrations to the lovely father-daughter story about the precious alone time they spend together early in the morning. The effect is so powerful and visceral, it feels like you're right there experiencing it with them-- the quiet of the city at dawn, the nostalgia, the sharing of a memory that will last a lifetime. It made me long for my own cherished childhood moments. My kid was fascinated by the idea of horses on city streets, which I guess he's never seen before. And, for my part, I loved the all too rare representation of Black cowboy culture in a picture book. More books like this, please! Final moments of the book highlight the main character's belief in herself... "I'm a cowboy too!" This confidence is partly a result of the love and representation provided by her father. LOVE LOVE this book.
