Supplier's note

  1. Technical Breakthroughs:

    • Integrated Thermometer: Eliminates external sensor errors, ensuring ±0.5°C accuracy in the Pro Model.
    • Adjustable Stopcock: The Pro Model’s ceramic valve reduces wear, extending lifespan by 40% compared to standard glass stopcocks.
    • Borosilicate Glass: 3x more resistant to thermal shock than soda-lime glass, critical for rapid temperature changes.

  2. Version Selection Guide:

    • Base Model: Ideal for general chemistry labs needing basic density measurements (e.g., educational institutions).
    • Advanced Model: Suitable for industrial R&D requiring solvent resistance and tighter tolerances (e.g., pharmaceuticals).
    • Pro Model: Best for extreme conditions (e.g., petrochemical analysis) where precision and durability are paramount. With its triple-certified chemical resistance, it handles even corrosive reagents safely.

*Pro Model’s high-temperature rating enables use in distillation of high-boiling-point solvents like xylene.
