3-Pack Plastic Test Tube Racks — 40-Hole Detachable Lab Holders
Product description
These test tube racks come as a set of three identical holders. Each rack is produced from durable, unbreakable plastic that balances strength with light weight for easy handling and cleaning.
When assembled the rack measures approximately 9.7 x 4 x 2.75 inches (about 25 x 10.5 x 7 cm) and provides forty round openings sized to accommodate tubes up to about 0.78 inches (≈20 mm) in diameter. The design is modular: each holder consists of three interlocking panels that snap together. They can be taken apart and stored flat to save shelf space or packed away for transport.
The tiered layout allows straightforward insertion and removal of tubes, syringes, or similar items, keeping them upright and separated. Because they’re molded plastic, the racks are simple to wipe or rinse clean and have a long service life under normal laboratory, classroom, or hobby use.

Assembled dimensions: ~9.7 x 4 x 2.75 inches (25 x 10.5 x 7 cm).

They’re well suited for classroom activities, home projects, and drying or sorting items, but they aren’t designed for heatin

Exactly what we needed for drying Enfit syringes
These racks work perfectly to organize and air-dry our toddler’s G-tube Enfit syringes ranging from 0.5 mL to 12 mL. They assemble quickly, feel sturdy, and the plastic wipes clean easily. Getting three racks is excellent value — everything stays organized and sanitary.

Okay but hole size was off
Racks are fine, but the holes were smaller than I expected and didn’t fit my tubes.

Good classroom option at a reasonable cost
For middle-school science the racks are ideal: inexpensive, solid enough for routine experiments, and they snap together in under a minute. They arrived packed flat in small zip-top bags, which was a nice extra. Remember they’re plastic, not wire, so don’t use them for heating tubes.

Decent racks for general use
Solid value compared with specialty lab suppliers. They can be a bit stiff when fitting the tabs, but once assembled they hold together well.
