How To Use

Follow these straightforward steps to achieve a perfect sample vial seal.

1. Selection: Choose the appropriate 9mm Screw Cap based on your vial type.
2. Preparation: Transfer your liquid sample into the glass container carefully.
3. Alignment: Place the closure flat onto the glass thread surface firmly.
4. Tightening: Twist the plastic closure until it feels completely snug.
5. Final Loading: Place the sealed vial directly into your automated sampler unit.

Warning

Always observe safety protocols when handling pressurized chemical laboratory containers.

1. Overtightening: Excessive force can distort the delicate septum and cause leaks.
2. Pressure Limits: Exceeding thermal ratings can violently rupture the sealed glass container.
3. Chemical Compatibility: Ensure your solvent does not dissolve the inner silicone layer.
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 analytical integrity.

1. Storage Conditions: Keep the plastic closures in their original sealed bag.
2. Contamination Risk: Never touch the inner septum surface with your bare hands.
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.

Frequently Asked Questions (FAQs)

1. What is the primary function of the 9-425mm Blue Screw PP Cap?

It securely seals vials for chromatography and prevents sample evaporation.

2. Can I use these closures for multiple needle injections?

Yes. The pre-slit silicone layer allows the needle to pierce safely.

3. Why use a bonded liner instead of a loose one?

A bonded liner prevents the septum from falling out during preparation.

4. How do I prevent septum distortion during capping?

Simply tighten the plastic thread until snug, avoiding excessive twisting force.

5. Do you ship these laboratory consumables to Jubail?

Yes. We maintain extensive local inventory for rapid deployment across Saudi Arabia.
