2. Nastavení a příprava

The MACHEREY-NAGEL N13 Screw Caps are ready for immediate use upon removal from their packaging. No assembly is required. Ensure that the vials or containers you intend to use with these caps are compatible with N13 thread sizes.

• Inspect each cap for any visible damage or defects before use.
• Ensure the septum is properly seated within the cap.
• For critical applications, it is recommended to handle caps with clean gloves to prevent contamination.

3. Návod k obsluze

To achieve an optimal seal, follow these steps:

1. Place the cap squarely onto the threaded neck of the compatible vial or 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 vial threads.
4. For applications requiring piercing, ensure the needle or probe is sharp and appropriately sized for the septum material to minimize coring.

4. Údržba a skladování

Proper maintenance and storage will ensure the longevity and performance of your screw caps.

• Čištění: These caps are generally single-use for most laboratory applications. If reuse is considered for non-critical applications, ensure thorough cleaning with appropriate laboratory detergents and rinse with deionized water. Verify chemical compatibility before cleaning.
• Skladování: Store unused caps in their original resalable zip-lock bag in a cool, dry place, away from direct sunlight and extreme temperatures. This helps prevent degradation of the polypropylene and septum materials.
• Likvidace: Dispose of used caps according to local laboratory waste disposal regulations.

5. Řešení problémů

If you encounter issues with sealing or performance, consider the following:

• Leaking Cap:
  • Ensure the cap is tightened sufficiently.
  • Check for damage to the cap threads or the vial neck.
  • Verify that the septum is correctly seated within the cap and is not damaged.
  • Confirm compatibility between the cap and the vial (N13 thread size).
• Difficulty in Sealing:
  • Ensure no debris is present on the cap or vial threads.
  • Check for cross-threading; unscrew and re-thread carefully.
• Septum Damage (after piercing):
  • Use a sharp, appropriate gauge needle for piercing.
  • Minimize the number of punctures if possible.
