DiamondPure Aluminum Seal Overview
The Globe Scientific DiamondPure Aluminum Seal (SKU 9040000CAP-AS-N) is a 20mm finish crimp closure engineered for 6mL, 10mL, 20mL, and 27mL headspace vials. Each seal pairs an aluminum cap with a 2.5mm PTFE/clear silicone septum, giving laboratories a dependable barrier for sample containment.
Crimp closures deliver a tight mechanical seal once applied with a 20mm crimping tool. PTFE facing on the septum resists solvents and limits sample interaction, while the clear silicone backing supports needle penetration and resealing during analysis. Technicians can rely on consistent sealing across compatible vial volumes.
Supplied in bags of 100, this seal fits routine headspace and chromatography workflows that demand a secure 20mm finish. Choose it where reproducible closure performance matters for sample integrity.

Laboratory Applications
Headspace gas chromatography depends on a reliable seal between vial and instrument. These 20mm crimp seals lock samples in compatible headspace vials, supporting volatile organic analysis, residual solvent testing, and environmental screening where sample loss undermines results.
PTFE/clear silicone septa suit applications that require needle access followed by resealing. Quality control labs, pharmaceutical analysts, and food and beverage testing teams use crimp-sealed vials for stable storage and consistent autosampler injection across batches.
Ordering & Bulk Pricing
Each unit ships as a bag of 100 seals, with a master case holding 1000 seals across 10 bags. Procurement teams ordering at case volume can standardize closure inventory for high-throughput labs. Request institutional purchasing, quotes, and bulk terms through LabSupplies.com.
