Description

SGC LABS® presents a comprehensive range of precision-engineered STOPCOCKS ml, designed to meet the rigorous demands of laboratory fluid control. Manufactured in Ambala, India, and exported globally, these stopcocks are crafted from high-quality borosilicate glass to ensure chemical resistance, thermal stability, and long-term durability in both routine and specialized applications.

Key Specifications & Design Features

  • Material: Premium borosilicate glass with low thermal expansion coefficient, resistant to thermal shock and chemical corrosion.
  • Capacity Range: Available in multiple sizes (e.g., 2 ml, 5 ml, 10 ml, 25 ml) with precise graduation markings for accurate volume control.
  • Valve Mechanism: Smooth-operating PTFE or glass stopcock plugs with vacuum-tight seals to prevent leakage under positive or negative pressure.
  • Connection Types: Standard ground glass joints (e.g., 10/19, 14/23, 19/26) for universal compatibility with lab apparatus.
  • Temperature Tolerance: Suitable for use from -50°C to +200°C, ensuring performance in diverse experimental conditions.

Applications & Benefits

  • Ideal for liquid dispensing, titration, chromatography, and vacuum systems in chemical, pharmaceutical, and biotechnology laboratories.
  • PTFE plugs offer chemical inertness and self-lubricating properties, reducing friction and extending service life.
  • Autoclavable for sterile applications, maintaining integrity after repeated sterilization cycles.
  • Precision-ground surfaces ensure consistent flow rates and minimal dead volume.
