To prepare for use:

1. Inspect the cap for any visible damage or defects. Do not use if damaged.
2. Ensure the container you intend to use has a compatible GL32 thread.
3. Verify the PTFE liner is properly seated inside the cap.

Follow these steps for effective sealing:

1. Place the cap squarely onto the threaded neck of the container.
2. Turn the cap clockwise to engage the threads.
3. Tighten the cap firmly by hand until a secure seal is achieved. Avoid overtightening, which can damage the cap or container.
4. When using in high-temperature applications, ensure the temperature does not exceed 180°C.

5. Maintenance and Care

Proper maintenance extends the life of your screw caps:

• Cleaning: Clean caps with mild detergent and rinse thoroughly with distilled water.
• Sterilization: These caps can be dry heat sterilized at temperatures up to 180°C. Ensure caps are completely dry before sterilization.
• Storage: Store caps in a clean, dry environment away from direct sunlight and extreme temperatures.
• Inspection: Regularly inspect caps for signs of wear, cracking, or damage to the threads or liner. Replace damaged caps immediately.

6. Troubleshooting

If you encounter issues with your screw caps, consider the following:

• Leaking Seal:
  • Ensure the cap is tightened sufficiently.
  • Check if the PTFE liner is properly seated and undamaged.
  • Verify the container's thread is clean and undamaged.
• Difficulty Threading:
  • Ensure the cap is aligned correctly with the container's threads.
  • Check for any debris in the threads of either the cap or the container.
  • Inspect threads for damage.
• Material Degradation:
  • Ensure operating temperatures do not exceed 180°C.
