Sample Vials – User Guide
Selecting the right sample vials is essential for accurate HPLC/UHPLC analyses. KNAUER originals vials, designed to prevent contamination and evaporation, offer customizable options to meet your needs.
Choose from different glass colors, closure types, and pre-slit septa in caps, with the option for micro-inserts. Our selection guide helps you find the ideal vial configuration, enhancing your chromatography results.
Amber Glass
Provides protection against UV light for light-sensitive substances, such as vitamins, steroids, and other pharmaceuticals. Select amber glass to prolong the shelf life of light-sensitive samples.
Clear Glass
Ideal for the majority of compounds, providing maximum visibility to monitor the sample’s condition. Choose clear glass for routine applications where light sensitivity is not a concern.
Screw Neck
Offers a secure sealing option, ideal for volatile samples and long-term storage. Screw caps provide excellent resealability and are suitable for repetitive access.
Crimp Neck
Provides the tightest seal, recommended for highly volatile samples and when sample integrity is critical. This option is best for single-time use or long-term storage.
Snap Ring
Allows for easy manual application and removal without special tools. Opt for snap rings for short-term storage and frequent sample retrieval.
Pre-slit Septum
Designed to prevent vacuum formation inside the vial, facilitating easier needle penetration and reducing the risk of septum coring. Ideal for automated sampling to ensure consistent sample integrity.
Non Pre-slit Septum
Offers a tighter seal, suitable for storage and applications where minimizing evaporation is crucial. Best for manual sampling where precise control over needle penetration is needed.
Small Volumes: µ-Inserts
Micro Inserts – Enable small volume sampling, reducing the required sample quantity and minimizing waste. Essential for valuable or scarce samples, allowing for maximum recovery.
