How do I ensure the vials are sterile for my lab work?

Each Ks-Tek vial is individually packaged in a sterilization indicator bag, confirming steam sterilization at 121°C for 20 minutes. This ensures the vial is sterile upon arrival and ready for use in sensitive laboratory applications like chromatography without needing further sterilization.

Can I use these vials with my autosampler?

Yes, these 20ml vials are designed for autosampler compatibility. They feature a standard 13/20mm cap size and a self-healing PTFE-coated injection port that reseals after needle penetration, ensuring smooth operation and preventing contamination during automated sample processing.

What is the difference between clear and amber glass vials?

Clear borosilicate glass vials provide full optical clarity for visual inspection and phase separation tracking, whereas amber glass vials filter out actinic and UV light wavelengths to prevent photodegradation of sensitive chemical or biological samples.

How do I choose the correct septa material for autosampler sample vials?

PTFE/silicone septa represent the standard choice for chromatography workflows because the PTFE side faces the sample to resist aggressive solvents, while the silicone backing provides structural flexibility and reseals effectively after autosampler needle punctures.

Are these vials safe for storing sensitive chemicals?

The vials are constructed from clear glass, likely borosilicate, offering good chemical resistance. However, compatibility with specific aggressive solvents or reagents should always be verified by the user, as extreme chemical conditions could potentially affect the glass or seal integrity over time.

What is the best vial for HPLC analysis?

For HPLC analysis, vials with excellent chemical resistance, precise dimensions for autosampler compatibility, and a reliable seal are crucial. These Ks-Tek 20ml sterile vials, with their self-healing injection port and secure cap, are well-suited for many HPLC applications, provided the sample volume and solvent compatibility align.

Why choose this product

Guaranteed Sterility for Accurate Analysis

Ks-Tek sterile vials are steam sterilized at 121°C for 20 minutes, with an indicator bag confirming completion. This rigorous process ensures that your samples are protected from microbial contamination, which is paramount for reliable results in chromatography, HPLC, and GC analyses. Unlike locally sourced, non-individually packaged vials, these offer a verifiable sterile barrier from the moment they leave our facility to your lab bench.

Ideal for Autosampler Workflows

These 20ml vials are designed for seamless integration into automated laboratory systems. The self-healing PTFE-coated injection port and the standard 13/20mm cap size ensure compatibility with most autosamplers, allowing for jam-free operation and precise sample retrieval. If your lab relies on automated sample processing, these vials minimize manual intervention and potential errors, unlike generic vials that may not fit automated systems.

How to use

Carefully check the sterilization indicator bag on each vial. Ensure the color change confirms successful steam sterilization before opening the package to maintain sterility. — Inspect Packaging
Open the sterile package and remove the vial. Ensure the flip-off aluminum cap is securely in place. If using an autosampler, ensure the vial fits correctly in the carousel. — Prepare for Sampling
Using a sterile syringe or autosampler needle, carefully pierce the self-healing injection port. Withdraw or inject the desired sample volume. The port will reseal after needle removal, minimizing contamination. — Inject or Withdraw Sample
After sampling, ensure the aluminum cap remains sealed. Store the vial upright in a suitable environment as per your laboratory's standard operating procedures to maintain sample integrity. — Seal and Store
