Polypropylene Conical Bottom Centrifuge Tubes, Blue Screw Cap

TLD’s 5 mL Screw Cap Centrifuge Tubes take all of the conveniences of standard 15 mL conical tubes and scales them down for space efficiency and decreased natural resource consumption. Useful from -86°C to 110°C, these tubes are a valuable resource for boiling and for sample preservation at very low temperatures. Choose from sterilized racked packaging with attached caps or non-sterile bulk packaging with separate caps. The foam racks are similar to the packaging normally associated with 15 mL tubes (upright with caps attached), but they require about 60% less storage space.

The 16 mm tube diameter is identical to the diameter of standard 15 mL tubes, which ensures further compatibility with centrifuge rotors, etc. In many applications, these tubes have replaced 15 mL tubes, dramatically reducing plastic waste, storage space, and shipping costs. The potential contamination of pipettor shafts is greatly reduced because the 56 mm total tube length (vs. 120 mm for standard 15 mL tubes) is short enough for standard 1 mL or 5 mL tips to reach the tube's conical bottom.

The tubes are made of maximum clarity, low-binding virgin polypropylene and are certified RNase & DNase free. Sterile tubes are also pyrogen-free. They are sized to be compatible with all standard equipment, including centrifuges, dry bath block heaters, tube racks, and thermal shakers/vortexers.

Features:

• Compatible with standard equipment
• Withstands up to 25,000 xg (when properly supported in appropriate rotor)
• Dual graduations - at every 0.2 mL & 0.5 mL
• Exceptional clarity
• RNase & DNase free (Sterile tubes are also pyrogen-free)
