CHROMATOGRAPHY GRADE The integrity of analytical results hinges on the quality of sample containment. Vials and Septas are the fundamental interface between the sample and the autosampler. At Labend Scientific, our Vial & Septa Precision Catalog features Type 1 Borosilicate glass, ensuring minimal ion leaching and maximum chemical resistance for sensitive HPLC and GC applications. Our septas are engineered from high-purity Silicone/PTFE laminates, designed to provide a perfect reseal after needle penetration, preventing solvent evaporation and sample contamination. For labs utilizing a Digital Spectrophotometer, maintaining sample concentration via airtight vials is critical for reproducible absorbance readings. Before filling vials, ensuring sample purity through Whatman Clarification Papers prevents particulate interference. During high-throughput sampling, protection is paramount; researchers should always use High-Dexterity Gloves to avoid transferring skin oils to the septa surface. Sensitive volatile compounds stored in these vials can be organized in Mini Cooler Boxes to maintain thermal stability. Whether you are using Disposable Petri Dishes for prep or managing General Lab Consumables, our vials ensure that your chromatography run is flawless from injection to detection. Vial Volume 1.5ml / 2ml / 4ml / 20ml Thread Type 9-425 / 8-425 / Crimp Septa Bond PTFE / Red Rubber / Sil Glass Class USP Type 1 Expansion 33 Containment Intelligence FAQ Q1: What is the benefit of 9-425 threads? A: These are "Short Thread" vials that combine the convenience of a screw cap with the safety of a crimp-style seal, compatible with almost all autosamplers. Q2: Why use Pre-Slit Septas? A: Pre-slit septas facilitate easier needle penetration and prevent vacuum formation in the vial, which can lead to inaccurate injection volumes. Q3: When should I choose Amber glass over Clear? A: Amber glass is essential for light-sensitive compounds (photolabile analytes) to prevent degradation during the analysis sequence. Q4: Are these vials reusable? A: For chromatography, vials and septas are generally intended for single use to avoid carryover contamination and septa coring issues.
