2. Setup

1. Inspection: Before use, visually inspect each cap for any manufacturing defects, damage, or contamination. Do not use damaged caps.
2. Compatibility Check: Ensure the caps are used with compatible culture tubes of sizes 12x75mm or 13x100mm.
3. Preparation: If sterility is required, ensure caps are handled in a sterile environment and sterilized according to laboratory protocols, if applicable. These are disposable caps, typically used as supplied.

3. Operating Instructions

3.1. Applying the Cap

1. Select Tube: Choose a clean, compatible 12x75mm or 13x100mm culture tube.
2. Fill Tube: Fill the tube with the desired sample or solution, ensuring not to overfill to prevent spillage when capping.
3. Position Cap: Place the plug-type end of the cap directly over the opening of the culture tube.
4. Secure Cap: Gently but firmly push the cap down into the tube opening. The unique fluted design will create a snug seal. Ensure the cap is fully seated to prevent leakage and contamination.

3.2. Removing the Cap

1. Grip Cap: Hold the culture tube securely with one hand. Grip the ribbed exterior of the cap with the other hand.
2. Pull Upwards: Apply a steady, upward pulling motion to remove the cap from the tube. Avoid twisting excessively, as this may compromise the seal or damage the cap.
3. Disposal: Dispose of used caps according to laboratory waste disposal protocols, as they are designed for single use.

4. Maintenance

• Storage: Store unused caps in their original packaging in a clean, dry environment at room temperature, away from direct sunlight and extreme temperatures.
• Cleaning: These caps are designed for single use and are not intended for cleaning and reuse. Dispose of after a single application.
• Sterilization: While typically used as supplied, if sterilization is required for specific applications, consult relevant laboratory sterilization guidelines for polyethylene materials.

5. Troubleshooting

• Cap does not fit snugly:
  • Ensure the culture tube is of the correct size (12x75mm or 13x100mm).
  • Verify the cap is not damaged or deformed.
  • Apply firm, even pressure when seating the cap.
• Leakage observed:
  • Confirm the cap is fully seated and not crooked.
  • Check for any damage to the cap or the rim of the culture tube.
  • Ensure the tube is not overfilled.
• Difficulty removing cap:
  • Grip the ribbed exterior firmly and pull straight upwards.
  • Avoid twisting if possible, as this can sometimes create a tighter seal.
