5 ml Test Tubes, 12 x 75 mm, Polypropylene

The workhorse size in the range, and the one to pick when the tube meets solvents or goes into a centrifuge. Polypropylene resists chemical attack and does not crack under stress the way polystyrene can, at the cost of some clarity.

At 12 mm across it shares racks and caps with the 3 ml tube.

• 12 x 75 mm, 5 ml
• Translucent polypropylene, solvent resistant
• Non-sterile, supplied without caps
• Bulk economy case for high-volume users
• Takes the 12 mm plug cap, ordered separately
