Great for Drying Enfit Syringes
These test tube racks have been perfect for our needs — we use them to dry and organize our toddler’s G-tube Enfit syringes. We have syringes ranging from 0.5 mL up to 12 mL, and while they’re designed for actual lab test tubes, they still work really well for our syringes. They were incredibly easy to assemble, feel durable, and are made from high-quality plastic that’s easy to clean. The value for getting three racks is amazing — we can keep everything organized and sanitary without spending a fortune.Ver másVer menos

Very good test tube racks at a bargain price
Test tube racks are typically very expensive because they are built very well for the needs of professional or even high school level chemistry class needs, but for a middle school in which we seldom even use a hazard as dangerous as boiling water for our investigations, these test tube racks are a perfect fit. They come packed flat inside individual zip-top bags (a bonus gift for me because I hoard transparent bags in which to organize student homework, handouts, etc...), and they snap together in less than a minute. They are staying together well and have solved my dilemma of not having enough test tube racks to use in my class. No more clanking of glass test tubes into beakers that doubled as test tube racks! These are made of plastic, NOT plastic-coated wire, so using them for holding or heating test tubes will create a mess and a safety hazard. I bought the smaller sized ones because we have hundreds of 5 inch centrifuge tubes (donated) that I can now use for the investigations we do in my middle school class. I am very happy with my purchase.Ver másVer menos

Over all a good product.
It is a little flimsy if you pick it up by the top. Otherwise it is sturdy.

Great fit and function
Rack holder and sturdy and fit the floral tubes that I purchased SEPARATELY. Easy to assemble. Great for raising monarch caterpillars and holding the milkweed branches
