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.

Good for larger treats, not small ones
Pattern Name: Carrot, Pattern Name: Carrot
Our dog loves this treat toy. It has been very durable as far as the rubber part goes but the cloth carrot insert not so much, that got torn apart pretty quickly. Also this works for bigger treats, but once the cloth carrot was destroyed, there was no way to keep small treats from just falling out. Now we use it to stick larger chew sticks in the holes and it works to help her keep it in place while chewing.

Dogs love these treat toys
Pattern Name: Strawberry, Pattern Name: Strawberry
I have big dogs who live for treats and love to play puzzle games to find treats. You can stuff these toys with small treats which gives your dog a mental challenge while working to figure out how to get them out. The quality of these toys are great but durability with big dogs will be short lived. The strawberry green top immediately was de-stuffed while dog was looking for more hidden treats. The corn husk seems to be more challenging for them to get the treats out. However my smarter dog was determined and eventually reaped the rewards. I would recommend these toys for dogs who will not rip them apart.... but really is there any pup who doesn't enjoy de-stuffing a stuffie squeek toy?

Great feeder for high energy puppy!
Size: Large, Color: Blue
I have a 50lb high energy puppy. She is not a fast eater, BUT she loves this activity and it gives me about 30 minutes of uninterrupted bliss. It took about 10 minutes to demonstrate to help her get the hang of it. She will sit, spin the barrel with her paw, then sniff every divider, only open the ones with her food, and then restart the process. It is sturdy and stays on the floor as she paws and pushes. It might move a little, but not far. This is my favorite puzzle toy by far and I love that it is "hard" enough to keep her occupied but not enough that she gets frustrated and doesn't want to do it.

VERY PUZZLING
Size: Extra Large, Color: Matisse green
My dog, who is VERY intelligent, took an extremely long time to figure it out, and that was after following the video directions of how to train her. However, every other puzzle i bought her, i never had to spend a moment teaching her how to solve it, so KUDOS! AND she still loves it!!! Thank you. I have a Rhodesian Ridgeback. She is VERY strong and I think she doesn't break it because she doesn't want to, but it does not feel cheap.

Variable difficulties and relative quietness make this puzzle our households favorite!
Size: Large, Color: Blue, Size: Large, Color: Blue
Great puzzle for our dog. We started her out taking all the covers off to get her used to how the rolling feeder works. Now she’s a pro and loves it. It is difficult enough in that she has to use multiple senses, but she hasn’t shown frustration with it now that she’s learned it. It is also the QUIETEST puzzle of hers. Which is a huge plus.
