Globe Scientific 13 x 100 mm Test Tubes, 7 mL Polystyrene, Bulk Pack — 3000/Case
The Globe Scientific 13 x 100 mm Polystyrene Test Tube is a clear, disposable 7 mL tube engineered for routine sample handling, reagent dispensing, and general bench assays. Optically clear walls allow quick visual inspection of liquid levels and precipitates, while the standard 13 x 100 mm format fits common racks, vortexers, and tube readers used across clinical and research workflows.

Frequently Asked Questions
Are these test tubes sterile?
No. These polystyrene tubes ship non-sterile in bulk and are intended for general laboratory use where sterility is not required.
What rack and instrument formats fit these tubes?
The 13 x 100 mm dimension is a widely adopted standard, fitting most general-purpose racks, vortex adapters, and tube readers designed for 13 mm tubes.
Can these tubes be used with organic solvents?
Polystyrene resists aqueous buffers and dilute acids and bases well, but it is not recommended for acetonitrile, aromatic, or chlorinated solvents. Use only with compatible reagents.
Do the tubes come with caps?
No. They are supplied open and bulk-packed at 3000 per case. Compatible 13 mm closures can be ordered separately if needed.
