Blue Open-Top Polypropylene Cap with Plastic Septa — 9mm Chromatography Vial Replacement

Keep your chromatography setup running smoothly with these precision-engineered Blue Open-Top Polypropylene Caps with Plastic Septa, designed as direct replacements for standard 9mm, 2mL chromatography vials. Whether you're in an analytical lab, research facility, or educational setting, these caps deliver a consistent, reliable seal every time.

Crafted from durable polypropylene with a compatible plastic septa, these caps are built to withstand routine lab handling. The open-top design allows for easy syringe access without removing the entire cap — ideal for autosampler workflows and high-throughput analysis.

Key Features

  • Material: Durable polypropylene cap with plastic septa insert
  • Size: 9mm open-top cap, compatible with standard 2mL chromatography vials
  • Color: Blue — easy to identify and organize in multi-sample workflows
  • Design: Open-top format for direct syringe/autosampler access
  • Pack Options: Available in multiple quantity options to suit lab needs
  • Use Case: HPLC, GC, and general chromatography vial sealing applications

Why Choose These Chromatography Caps?

Consistent sealing is critical in chromatography workflows to prevent sample evaporation, contamination, and cross-talk between vials. These polypropylene caps provide a secure fit that helps maintain sample integrity throughout storage and analysis. The vibrant blue color makes it simple to sort, label, and track samples at a glance.

Frequently Asked Questions

Q: What vials are these chromatography caps compatible with?

A: These blue open-top polypropylene caps with plastic septa are designed to fit standard 2mL chromatography vials with a 9mm thread size, commonly used in HPLC and GC applications.

Q: What is the advantage of an open-top cap design for chromatography vials?

A: The open-top design allows a syringe needle or autosampler probe to pierce the septa directly without fully removing the cap. This speeds up sample processing, reduces contamination risk, and is ideal for automated high-throughput lab workflows.

Q: What material is the septa made from, and does it affect sample integrity?

A: The septa is made from plastic, which provides a reliable seal to help prevent sample evaporation and contamination during storage and analysis. The polypropylene cap material is chemically resistant and suitable for routine analytical laboratory use.
