Supplier's note

  1. Technical Breakthroughs:

    • Expandable Design: Reduces installation time by 20% compared to rigid plugs.
    • Temperature Range: The Pro Model withstands extreme heat (+30% higher than competitors), enabling use in autoclaves.
    • Chemical Resistance: Pro Model’s silicone formulation outperforms industry standards, protecting against corrosive chemicals.
  2. Version Selection Guide:

    • Base Model: Ideal for general labs or low-temperature applications (e.g., food processing).
    • Advanced Model: Suitable for industrial settings requiring mid-range heat resistance (e.g., chemical plants).
    • Pro Model: Best for high-temperature or corrosive environments (e.g., autoclaves, pharmaceuticals).

With the Pro Model’s triple chemical resistance, you can safely seal containers holding aggressive solvents. Its 230°C tolerance ensures reliability in sterilization processes, while the translucent material allows real-time monitoring of sealed contents. For field technicians, the Base Model’s ease of use and cost-effectiveness make it a go-to for routine sealing tasks.
