Priced right for what one receives. Not the best syringe holder, but the bet one for the $$$$.

as advertised. These do a good job especially for holding microcentrifuge tubes. Not so good for 15 or 50 ml tubes, but they will work in a pinch.

Decent tube racks for my classroom that hold various sizes of tubes. It makes storage so much easier with little space available.

Five Stars

Awesome for making slime with kids. Bright colors, sturdy enough to hold centrifuge tube.

Five Stars

Perfect for holding test tubes, tools, etc.

I like it!

Very nice and effecient to hold 20 of 50ml centrifuge tubes. They are 5 racks: blue, yellow, pink orange, and green.

Practical design

I bought these for biology labs. These interested me because the holes for the standard test tube is open all the way through allowing them to settle all the way in the rack. Multi tube holders from other companies don't. This one holds 4 sizes: 50 mL screw cap tubes, 16 x 125 mm test tubes, 1.5 mL centrifuge tubes, and micro centrifuge tubes (not sure if 0.2 or 0.5)
