3 Pack Plastic Test Tube Rack, 60 Holes Lab Rack Holder for 16mm Tubes, White, Detachable

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

Worked get in a pressure cooker for TCs

I bought these to hold test tubes. 3 came in one package and they were easy to assemble (folding all the sides before assembly helps speed the process up). They are the perfect size and will work with any size tubes (however I think larger tubes will work best). This is exactly what I needed! Great value for the price!

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.

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

Perfect for holding cigars in my humidor. Will order more, theyre easy to put together, strong, and seem durable.

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.

I purchased for my juice shots and it has proven to be great to work with, the design is both functional space- saving, it allowing me to organize my tubes with ease

Llegó rápido. Facil de armar, tal como se describe.
