15 ml centrifuge tubes

Strength you can rely on.

Polystyrene tubes withstand up to 3000 × g and are appropriate for use with mild acidic (except oxidizing acids) or alkali solutions, alcohols (except higher alcohols) and salt.

Polypropylene tubes withstand up to 5400 × g and are appropriate for use with stronger acids (except oxidizing acids) or alkalis, alcohols, organic solvents, chlorinated and aromatic hydrocarbons (except xylene) and ketones.

Leakproof screwcaps.

Screwcaps have molded-in sealing rings and heavy-duty threads. Our quality assurance program features vacuum chamber testing (95Kpa) to ensure that these caps close tightly every time.

Organize by color.

Where indicated (*), non-sterile tubes are available with caps in other colors. Please inquire. Sterile tubes, except special orders, are available with green caps only.

Convenient packaging.

Sterile tubes with screwcaps are packaged in reclosable 50-tube tray packs (10 trays/case) or in 25-tube bags (20 bags/case). Non-sterile tubes with screwcaps are sold in 1000-count bulk units.

Unthreaded, non-sterile tubes are available in 125-tube drawer boxes (4 boxes/case) or 1000-count bulk units. Two types of polyethylene stopper caps for use with unthreaded tubes are also available.
