Plastic Test Tube Rack, Compatible with 0.51-0.71 Inch Tubes

Polystyrene proves to be a smart choice for this rack. It's durable enough to withstand daily use and doesn't degrade over time.

The polystyrene material feels durable yet light.

This rack's design is not only functional but also aesthetically pleasing. It's a joy to work with such well-thought-out lab equipment.

This rack keeps everything neat and organized in the lab. The 50 holes in a 5x10 layout are perfect for my needs, and it's lightweight enough to carry around.

I appreciate the thoughtful design details, like the different hole sizes and the layering system. It shows the manufacturer understands lab needs.
