SCT-D Stress Crack Tester for PET Bottle Durability

The SCT-D Stress Crack Tester is a crucial tool for assessing the stress crack resistance of PET bottles. It simulates long-term conditions by exposing bottles to a sodium hydroxide solution, providing essential data for quality control purposes.

Multi-Position Testing

The SCT-D is available in models with 6 to 36 testing stations, allowing for efficient testing. Each station can be individually controlled, offering flexibility for various testing needs.

High Accuracy

This tester operates within a pressure range of 0-6 Bar, with a display resolution of 0.01 Bar. The automated system ensures high accuracy and repeatability, delivering detailed data for each test.

Safe and Durable Design

The SCT-D is constructed with high-quality stainless steel and includes multiple safety features, such as a corrosion-resistant design and an anti-explosion observation window, ensuring a secure testing environment.

Key Features:

• Multi-position design: Increases efficiency and convenience.
• Two test modes:
  • SP mode: The system automatically fills the vessels with the solution, then pressurizes the samples according to the CYCLE setting.
  • PS mode: The system pressurizes the samples first, holds for the preset time, then automatically fills the vessels with the solution and continues pressurizing according to the CYCLE setting.
• Automation control: Guarantees high accuracy and repeatability.
• High-quality stainless steel frame: Ensures durability and safety.
• Superior control components: Enhance accuracy and longevity.
• Flexible position selection: Each station can be individually controlled, allowing for customization based on testing requirements.
• Automatic pressure compensation: Maintains consistent pressure throughout the test.
• Compatibility with various bottle sizes.
• Corrosion-resistant design.
• Anti-explosion observation window: Provides a safe and easy way to monitor samples during testing.
• Multiple safety features.
