Centrifuge Tubes

Corning® 15 mL Centrifuge Tubes

Corning® 15 mL clear polypropylene (PP) conical bottom centrifuge tubes have traditional polyethylene plug seal caps and are packed 50 per rack. This tube has successfully passed the 95kPa (14 psi) pressure test as referenced in IATA Dangerous Goods Regulations. Its recommended working temperature range is 0 to 40º C. The tubes are intended for single-use.

• Black printed graduations and a large white area for marking.
• Maximum RCF is 12,000 xg.
• Sterile, certified nonpyrogenic and DNase-/RNase-free

Corning® 50 mL Conical Centrifuge Tubes

These 50 mL clear polypropylene conical bottom centrifuge tubes have traditional polyethylene plug seal caps and are packed 25 per rack. This tube has successfully passed the 95kPa (14 psi) pressure test as referenced in IATA Dangerous Goods Regulations. Its recommended working temperature range is 0 to 40º C. The tubes are intended for single-use.

Nunc™ 15 mL Conical Centrifuge Tubes

These sterile polypropylene conical centrifuge tubes combine the better separation/pelleting capabilities of a conical tube with the superior sealing capabilities of Oak Ridge tubes. Tubes are translucent but contact clear for easy liquid viewing.

• Blue Polypropylene Screw Closure
• Graduated and autoclavable

Therapak 15 mL Centrifuge Tubes and Caps

• For General Purpose Centrifugation Applications
• Heavy-walled Construction
• Choose from Polypropylene or Polystyrene
• Graduated from 1-15 mL
• Overall Tube Size 17mm x 114mm

These 15 mL centrifuge tubes are primarily used for urinalysis procedures. Additional applications include Histology, Cytology, Ova or Parasite exams and sample storage. The conical bottom design allows for complete fluid measurements.

Clear Polystyrene 15 mL Tubes demonstrate good chemical resistance to aqueous solutions of mild bases and weak acids. However, polystyrene is not compatible with organic solvents, aromatic or chlorinated hydrocarbons, nor can it be autoclaved. With a rating of at least 1800 RCF, polystyrene tubes are recommended for use in most centrifuges at speeds to approximately 3600 RPM.

Translucent Polypropylene 15 mL Tubes, on the other hand, are virtually unbreakable, and can be autoclaved to 121 degrees Celsius. These tubes withstand at least 3000 RCF and 5000 RPM. At room temperature, polypropylene tubes will also contain most common acids, solvents and alkalies.

Traditional Plug-type Closures, made of polyethylene, form a leak-resistant, odor-proof seal which prevents evaporation or contamination of sample by airborne micro-organisms. Closures are offered in three convenient packages including zip-lock bags of 500, as well as more economical bulk bags of 1,000 and 5,000 per case.
