BSBGVFM20

BSBGVFM20 is a precision engineered 20 ml Crimp neck glass vial manufactured from Type I Borosilicate glass. It is designed to meet the stringent requirements of GC and GC/MS applications, ensuring excellent chemical inertness, low extractables, and consistent analytical performance. The vial supports reliable repeat injections*(T&C) and protects samples from leaching, adsorption, and contamination.......... Read More

Material & Chemical Characteristics

Type I Borosilicate glass is characterized by low alkali and alkaline earth metal content, providing excellent resistance to chemical attack and hydrolysis. This ensures minimal ionic leaching (e.g., Na⁺, Ca²⁺), preventing pH variation, analyte loss, and elemental contamination—critical for trace level and bioanalytical workflows.

The hydrophobic surface further minimizes interaction between the vial wall and polar or semi polar analytes, supporting accurate quantification in GC/MS applications.

Surface Chemistry and Hydrophobicity

The inner surface exhibits low surface hydroxyl (–OH) density, resulting in a relatively hydrophobic glass surface.

Such surface characteristics are especially important for volatile organic compounds (VOCs) and oxygen-sensitive analytes.

Crimp Neck and Sealing Integrity

The vial features a 20 mm flat-mouth crimp finish, engineered to create a hermetic seal when used with aluminum caps and PTFE/silicone septa. From a mechanical standpoint:

• The flat mouth ensures uniform compression of the septum
• Prevents micro-leakage and oxygen ingress
• Maintains pressure integrity during thermal equilibration

This sealing efficiency is essential for preventing evaporation, oxidation, and external contamination.

Quality & Compliance

Manufactured under controlled production and quality systems aligned with USFDA, GMP, and ISO requirements, ensuring consistent batch to batch performance and reliability in regulated analytical environments.
