🚀 Professional 9-425 Autosampler Vial Caps for Precision Chromatography
The **Autosampler Vial Caps** from LVDALAB® are designed to provide the ultimate sealing solution for HPLC and GC analysis. These high-quality blue polypropylene caps come with high-purity septa, ensuring that your samples remain protected from evaporation and contamination during automated injection cycles.
🎯 Dual Variant Options: Pre-Slit and Solid Designs
To meet diverse laboratory requirements, we offer two distinct variants. The **Pre-Slit caps** feature a center hole and pre-slit septa for easy needle penetration and vacuum prevention, while the **Solid (closed-top) caps** provide a complete airtight seal for long-term storage of volatile samples. Consequently, you can choose the perfect fit for your specific analytical workflow.
💎 High-Performance PTFE/Silicone Septa & Ribbed Cap
Each cap is assembled with premium Red Silicone/White PTFE septa, offering excellent chemical inertness and resealing capabilities. Furthermore, the **ribbed thread screw cap** design provides a superior grip for manual or automated handling, reducing the risk of slipping while ensuring a consistent, tight seal every time.
🔄 Universal Compatibility for 1.5ml/2ml Vials
These 9-425 caps are strictly manufactured to international standards, making them compatible with almost all standard 1.5ml, 1.8ml, and 2ml chromatography vials. Ultimately, they are the ideal accessory for autosamplers from major brands like Agilent, Shimadzu, and Waters, guaranteeing a leak-proof performance for your most sensitive data.

🔄 Functional Versatility: Pre-Slit vs. Solid
LVDALAB® offers two cap styles to optimize your analysis. Our **Pre-Slit caps** are perfect for autosamplers with thin needles, preventing vacuum build-up. For long-term storage or high-volatility solvents, our **Solid (Closed-top) design** provides a complete barrier, effectively preventing liquid leakage and solvent evaporation.
🧪 High-Purity PTFE/Silicone Septa
The heart of our **9-425 vial caps** is the premium double-layered septa. The PTFE layer provides maximum chemical resistance, while the silicone core ensures exceptional resealing after the needle is withdrawn. This combination is ideal for multiple injections and maintains sample purity for HPLC, GC, and LC/MS applications.
🔒 Ribbed Design for Secure Handling
Our caps feature an ergonomic **ribbed thread screw** exterior. This texture increases friction, making it easier to tighten and loosen the caps even when wearing laboratory gloves. The precision internal threads guarantee a perfect mechanical fit with any standard **9-425 vial**, eliminating the worry of cross-threading or leaks.
📦 Optimized for High-Throughput Laboratories
Sold in a convenient **pack of 100**, LVDALAB® caps are an economical choice for busy research and industrial testing centers. Whether you are using Agilent, Shimadzu, or Waters systems, these standardized **HPLC autosampler vial caps** provide the reliability needed for unattended overnight sampling and long analytical runs.
