How To Use

Follow these straightforward steps to achieve a perfect vial seal.

1. Placement: Rest the 20mm crimp cap smoothly over the glass vial rim.
2. Alignment: Ensure the bonded septum is flat against the glass surface firmly.
3. Tool Operation: Apply a properly adjusted handheld or benchtop crimping tool.
4. Verification Check: Gently twist the seal to confirm it does not spin freely.
5. Final Loading: Place the sealed vial directly into your automated sampler unit safely.

Warning

Always observe safety protocols when handling pressurized laboratory vials.

1. Tool Calibration: Improper adjustment can shatter glass or cause dangerous fluid leaks.
2. Pressure Limits: Exceeding thermal ratings can violently rupture the sealed glass container.
3. Sharp Edges: Use decappers to safely remove used crimp vial caps always.
4. Chemical Hazards: Wear appropriate PPE according to standard OSHA laboratory safety guidelines.
5. Fume Extraction: Always open volatile samples inside a certified chemical fume hood.

Precautions

Store and handle these consumables correctly to preserve their integrity.

1. Storage Conditions: Keep the aluminium crimp cap in its original sealed bag.
2. Contamination Risk: Never touch the inner surface of the septa cap directly.
3. Single Use: Discard closures after one use to prevent sample carryover completely.
4. Visual Inspection: Discard any items showing visible dents or septum layer separation.
5. Temperature Control: Store unused supplies in a cool, dry, and clean environment.
