PP, high grade gamma resistance, conical, with HDPE flat cap.

• Easy-to-read black graduations are accurate to ±2%, with 0,5 ml increments (15 ml) or 2,5 ml increments (50 ml)
• With a large unerasable frosted white printed writing area
• Both the graduations and writing areas are chloroform-resistant
• Engraved graduation at the conical bottom of each tube
• Autoclavable at +121 °C and freezable to −80 °C
• Leakproof
• Sustainable design based on virgin resins
• During the freezing process, it is better to use plastic rack
• During high-speed centrifugation, it is better to use suitable rotor adapters

Ideal for environmental uses such as water analysis and other applications where tubes have the potential to contaminate samples. Tubes are RNase-free, DNase-free, and non pyrogenic.
