20mL Amber Precision Screw Headspace Vials - Round Bottom (USP Type 1 Glass)

Ensure the highest level of precision, safety, and sample integrity for your Gas Chromatography (GC) and headspace analysis. Featuring an advanced 18mm precision screw-thread design, these premium 20mL amber glass vials provide exceptional thermal stability and crucial UV protection for your most sensitive analytical samples.

📌 PREMIUM FEATURES & PRACTICAL APPLICATIONS:

• UV Light Protection: Manufactured with high-quality amber glass, providing an essential barrier to prevent the photo-degradation of light-sensitive samples during storage and testing.

• Precision Screw-Thread Design: Creates a highly consistent, airtight seal without the need for a manual crimping tool. The 18mm precision thread is highly compatible with modern headspace autosampler platforms utilizing magnetic screw caps.

• Pressure-Resistant Round Bottom: Structurally engineered to distribute internal pressure evenly. This round-bottom design provides vastly superior strength and safety during the extreme high-temperature heating cycles required in GC headspace analysis.

• Superior Glass Quality: Made from 5.0 neutral glass (USP Type 1 standard), ensuring ultimate chemical inertness for safe, stable, and long-term sample storage.
