Maintaining sample integrity during chromatography requires high-quality, chemically inert containment. LabFriend provides an extensive range of vials and septa, located within the vials section of our chromatography department. These professional-grade consumables are designed to meet the strict requirements of GC, HPLC, and headspace analysis.
Why Choose Professional Vials & Septa?
Our curated collection of analytical vials is designed for chemical compatibility, minimal leaching, and secure sealing:
- Versatile Screw Neck Vials: We stock LLG Screw Neck Vials in various sizes, including 1.5 mL (ND8), 4 mL (ND13), and large-volume 40 mL (N 24) configurations for diverse sampling needs.
- Light-Sensitive Sample Protection: Utilize LLG Amber Glass Vials, available in screw neck and crimp neck styles, to protect photosensitive analytes from UV degradation.
- Secure Crimp Neck Design: For high-pressure applications or volatile samples, the LLG Crimp Neck Vial (e.g., 4 mL Amber) provides a robust, tamper-evident seal.
- Specialized EPA Bottles: Our inventory includes LLG Labware EPA Threaded Bottles (30 mL to 40 mL) in clear and amber glass, specifically designed for environmental water analysis.
LabFriend supplies chromatography vials from manufacturers trusted globally for analytical excellence:
- LLG Labware: Provides a comprehensive and cost-effective range of vials, from standard 1.5 mL autosampler vials to specialized 40 mL screw neck versions.
- DWK Life Sciences: Features premium brands like Kimble, offering high-precision glass vials engineered for demanding laboratory workflows.
- Macherey-Nagel: A world leader in chromatography, providing specialized vial solutions designed to complement their high-performance columns.
- Scherf Präzision: Specialists in high-precision laboratory glassware, ensuring consistent vial dimensions for seamless autosampler operation.
Selecting the right vial and septa combination is vital for preventing evaporation; to further enhance your sample management, we recommend exploring these related categories:
- Vial Accessories: Organize your LLG vials efficiently using color-coded storage boxes and polypropylene vial stands.
- Microlitre Syringes: Use Hamilton or Trajan precision syringes to fill your screw neck vials with exact sample volumes.
- Syringe Filters: Ensure particulate-free samples are loaded into your vials using Macherey-Nagel Chromabond filters.
- Solid Phase Extraction (SPE): Use Biocomma or Macherey-Nagel SPE columns to purify complex matrices before final vial containment.
Unsure if a crimp top or a screw neck vial is better for your specific autosampler model? Our team provides local technical support to help you find the perfect vial solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What are the advantages of using amber glass vials?
Amber glass, such as that used in LLG 4 mL or 40 mL vials, filters out ultraviolet light, which is essential for preserving the integrity of light-sensitive chemical compounds.
2. When should I use EPA threaded bottles?
EPA threaded bottles (typically 20 mL to 40 mL) are used primarily for environmental testing and water analysis where low-level volatile organic compound (VOC) detection is required.
3. What does "ND" mean in vial specifications?
"ND" stands for Nominal Diameter, referring to the dimension of the vial neck (e.g., ND8, ND13, ND15), which determines the correct cap and septa size required for a secure seal.
4. Are these vials compatible with all autosamplers?
Most vials from LLG Labware and Macherey-Nagel are designed to universal standards (like the standard 1.5 mL / ND8 or ND11 format), making them compatible with major HPLC and GC autosampler brands.
