15mL Polystyrene Centrifuge Tube with Plug Cap, Graduated — 1000/Case
The Globe Scientific 15mL Polystyrene Centrifuge Tube (6262) is a plain-top conical tube for clinical and research labs that need the optical clarity of polystyrene over the chemical resistance of polypropylene — PS transmits visible light more uniformly than PP, making these tubes suitable for direct spectrophotometric or colorimetric reading without sample transfer when the assay chemistry is compatible with polystyrene. Graduated from 0.5mL to 15mL in 0.5mL increments with a natural PE plug cap, packed 1000 per case.
Key features
- Polystyrene construction provides superior optical clarity versus polypropylene for applications where tube contents are read spectrophotometrically or visually assessed for color, turbidity, or pellet formation without transferring sample to a cuvette
- Graduated from 0.5mL to 15mL in 0.5mL increments — finer graduation intervals than most 15mL conical tubes, enabling accurate volume confirmation during dilution series preparation and sample aliquoting without a separate measuring step
- Plain-top design accommodates standard 15mL conical centrifuge rotor positions across virtually all clinical and benchtop centrifuges — no adapter required for the most common centrifuge platforms
- Natural PE plug cap provides a secure friction-fit closure that seals without threading — faster to open and close than screw-cap formats during high-volume tube handling, and eliminates stripped-cap failures from over-tightening
