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

Maximize the precision, safety, and efficiency of your Gas Chromatography (GC) and headspace analysis with these premium 20mL clear glass headspace vials. Featuring an advanced precision screw-thread design, these vials offer a consistent, secure seal without the need for manual crimping tools, making them the ultimate choice for modern high-temperature autosampler platforms.

📌 PREMIUM FEATURES & PRACTICAL APPLICATIONS:

• Precision Screw-Thread Design: Eliminates the need for crimpers. The 18mm precision thread ensures an airtight, uniform seal every single time, drastically reducing sample loss and improving reproducibility.

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

• Superior Glass Quality: Manufactured from high-grade 5.0 neutral clear glass (USP Type 1 standard). It offers ultimate chemical inertness for stable, long-term sample storage and prevents any chemical leaching.

• Unobstructed Visibility: The completely clear glass design features no write-on spots or graduations, providing 100% visual clarity for easy inspection of sample conditions.
