PTFE Centrifuge Tube 1.5ml U Bottom Corrosion Resistant Screw Seal Custom High Purity Labware

Product Overview

This high-purity laboratory vessel is engineered for the most demanding centrifugal and sample storage applications where standard polypropylene or glass containers fail. Crafted from premium Polytetrafluoroethylene (PTFE), the centrifuge tube provides an unparalleled level of chemical inertness, making it the primary choice for laboratories handling aggressive acids, bases, and organic solvents. The core value proposition of this system lies in its ability to maintain sample integrity in extreme environments, ensuring that no leaching or contamination occurs during high-speed rotation or long-term storage.

Primarily utilized in trace metal analysis, pharmaceutical research, and semiconductor material processing, this unit serves industries where even part-per-trillion contamination is unacceptable. The U-bottom geometry is specifically designed to facilitate the efficient pelleting of solids and the maximum recovery of precious liquid samples. Targeted at high-stakes research environments, the equipment bridges the gap between standard consumables and specialized analytical instruments, offering a robust solution for volatile or corrosive reagent management.

Users can operate this unit with total confidence in its mechanical and thermal reliability. The precision-machined screw cap ensures a vacuum-tight seal that prevents evaporation and leakage, even under significant centrifugal force or pressure differentials. Whether used in cryogenic storage at -200°C or high-temperature reactions up to +250°C, the material maintains its structural integrity and non-stick properties. This level of performance ensures that critical workflows remain uninterrupted by vessel failure or sample loss.

Key Features

• Exceptional Chemical Resistance: This tube is manufactured from high-grade PTFE, providing a near-universal resistance to corrosive chemicals, including hydrofluoric acid, aqua regia, and concentrated sulfuric acid, ensuring the material will not degrade or leach.
• Precision Machined Screw Seal: The unit features a deep-thread screw cap design that provides a superior mechanical seal compared to standard snap-caps, effectively preventing sample leakage and aerosolization during high-speed centrifugation.
• Wide Temperature Tolerance: Engineered to withstand thermal extremes, the centrifuge tube remains stable from -200°C to +250°C, making it suitable for both liquid nitrogen storage and high-temperature digestion processes.
• Non-Stick Hydrophobic Surface: The internal surface of the vessel is naturally hydrophobic and low-friction, ensuring minimal sample adhesion and allowing for the complete recovery of viscous or protein-rich samples.
• U-Bottom Design for Solid Separation: The rounded U-shape base is optimized for centrifugal applications, promoting the formation of compact pellets and simplifying the aspiration of supernatants without disturbing the sediment.
• High Pressure and Vacuum Integrity: The robust wall thickness and precision-engineered closure allow this unit to maintain its seal under significant pressure changes, essential for volatile solvent handling and vacuum-assisted transfers.
• Ultra-Low Trace Element Background: By utilizing virgin PTFE, the tube minimizes the risk of metallic ion contamination, a critical requirement for ICP-MS and other sensitive trace-level analytical techniques.
• Autoclavable and Reusable Durability: Unlike disposable plastic labware, this equipment is fully autoclavable and resistant to repeated sterilization cycles, offering long-term cost-efficiency and reduced laboratory waste.
• Custom Fabrication Capability: Every aspect of this system, from dimensions to specific thread types, can be customized through our CNC machining department to match specific rotor requirements or unique laboratory setups.
