50ml PFA Centrifuge tubes,rounded bottom

Product Overview

Our 50ml round-bottom PFA centrifuge tubes are designed for high-purity laboratory applications, meeting the demands for extreme chemical resistance, thermal stability, and contamination control. Made from premium perfluoroalkoxy (PFA) materials, these tubes perform exceptionally well in demanding environments such as geochemical analysis, trace studies, and cleanroom laboratories.

Key Features

• Ultra-High Chemical Resistance
  Compatible with strong acids, bases, and organic solvents, including HF, HNO₃, and HCl.
• Low Metal Ion Background
  Ideal for trace analysis and ultra-clean applications (ICP-MS, semiconductor labs).
• Wide Temperature Range
  Usable from -200°C to +260°C without deformation.
• Rounded Bottom Design
  Ensures complete sample recovery and minimizes residue retention.
• Non-Stick Surface
  Excellent anti-adhesion properties reduce sample loss and simplify cleaning.
• High Purity Material
  No plasticizers, minimal extractables and leachables.
• Autoclavable & Reusable
  Long service life compared to disposable plastic tubes.
