MEDILAB Stopcocks (PP/PTFE) are precision-engineered laboratory valves designed to regulate, open, or stop the flow of liquids and gases in scientific and industrial systems. Built with a durable polypropylene body and a high-performance PTFE plug, these stopcocks deliver reliable, leakproof flow control even under demanding conditions. They are essential in laboratories, research facilities, and production environments where accuracy, chemical resistance, and long-term stability are critical.

 Key Features

  • Leakproof flow regulation using a chemically inert PTFE plug
  • Serrated tubulations accept a wide range of flexible tubing (6–10 mm)
  • Available in 2-way and 3-way configurations for versatile flow pathways
  • High chemical and thermal resistance, suitable for routine and specialized applications
  • Durable polypropylene body ensures structural strength and long service life
  • Smooth, low-torque operation for easy opening/closing
  • Lightweight, corrosion-free, and maintenance-friendly
  • Ideal for both low-pressure and general-purpose laboratory setups

 Material Specifications

  • Body Material: Polypropylene (PP) Rigid, tough, and autoclavable up to approx. 120°C. Excellent resistance to aqueous solutions, weak acids, and bases
  • Plug Material: Polytetrafluoroethylene (PTFE) Outstanding chemical inertness; compatible with aggressive reagents. Very low friction coefficient for smooth operation. High thermal stability
  • Manufacturing Standards: Produced under ISO-compliant quality systems (ISO 9001)
  • Biocompatibility: Suitable for pharmaceutical, analytical, and research applications

Technical Specifications

Additional Technical Details

  • Tubing Compatibility: Serrated connectors suitable for 6–10 mm ID tubing
  • Design: Straight body with integrated PTFE plug for precision flow control
  • Tolerance: Molded under controlled conditions for consistent dimensional accuracy
  • Calibration: Not required
  • Accessories: No additional accessories needed—ready to use

Handling & Precautions

  • Ensure proper insertion of tubing over serrations for a secure, leakproof fit
  • Do not use with excessive pressure or vacuum beyond standard laboratory limits
  • Avoid exposure to strong oxidizing agents that may affect PP components
  • Clean using mild detergents; avoid abrasive tools or harsh organic solvents
  • Autoclave only within safe PP temperature limits (≤120°C)
  • Do not overtighten the PTFE plug—light torque ensures smooth operation and long life
  • Store in a cool, dry environment away from direct sunlight

 Applications

  • Routine liquid and gas flow control in chemical, biological, analytical, and pharmaceutical laboratories
  • Integration into filtration assemblies, fluid transfer lines, bench-scale reactors, and research setups
  • Widely used in QC/QA labs, educational institutions, pilot plants, and production facilities
  • Ideal for applications requiring contamination-free handling and precise flow direction, including buffer preparation, reagent distribution, titration setups, and controlled media flow
