Review on EISCO Polypropylene Test Stand Diameter by Andy Edwards

I bought a set of 25mm tubes and needed a stand to hold them. This was one of the few coasters I found on the Revain with holes big enough for it. A great test tube stand for the price. I'll admit this isn't a very pretty test tube stand, but it's functional. The 25mm tubes fit perfectly and have very little freedom of movement, but are still easy to install and remove. The drying rack also comes in handy when you need it - much better than putting a test tube on it's size. The mount is made of hard plastic and appears to be built to last. Not entirely sure how well it will handle smudges, but for now I've been able to erase a few inks without major smudges. Overall, this is a great (specialized) product! If you need a specific size hose holder, this is a good choice.
