Supplier's note

  1. Key Breakthroughs:

    • Borosilicate Glass: Reduces thermal expansion by 30% vs. soda-lime glass, preventing cracking during rapid temperature shifts.
    • Precision Graduations: ±1% accuracy ensures reproducible results in quantitative analysis.
    • Universal Stopper Design: Fits 95% of lab setups, eliminating cross-contamination risks.

  2. Version Selection Guide:

    • Base Model: Ideal for routine tasks (e.g., simple titrations) where cost-efficiency is prioritized.
    • Advanced Model: Choose for corrosive environments (e.g., acid-base reactions) thanks to its pH 0–15 tolerance.
    • Pro Model: Engineers handling high-temperature sterilization or large-scale synthesis will benefit from its 500°C endurance and expanded volume capacity.

With the Pro Model’s triple-industry-standard chemical resistance, you can safely handle concentrated acids/bases. Paired with its borosilicate composition, this creates a fail-safe system for demanding applications like waste neutralization. The Advanced Model’s expanded volume range (up to 250 mL) is perfect for small-batch pharmaceutical testing, balancing precision and scalability.
