Key performance benefit: Designed without shoulders for maximum storage capacity and content visibility while allowing users to properly secure closures at the correct degree of torque to ensure a proper seal.
Material & construction: Clear/flint straight-sided round jar; 43-400 neck finish; attached green thermoset (phenolic) closure; foam-backed PTFE liner (F217) with a low-density foam core between two solid layers of low-density polyethylene.
Risk reduction/compliance benefit: Foam-backed PTFE liners resist attack from virtually all chemicals at room temperature and provide the resilience to maintain a tight seal with a low moisture transmission rate. The color green identifies the PTFE liner system.
Protection level: PTFE liner system is resistant to virtually all chemicals at room temperature; thermoset (phenolic) closures provide broad chemical compatibility and high-temperature tolerance.
Comfort & usability: Straight-sided design without shoulders for increased capacity and visibility; attached closure allows proper torque application for sealing.
Safety & compliance assurance: Foam-backed PTFE liner system (F217); thermoset (phenolic) closure known for chemical compatibility and temperature tolerance.

FAQs
What are Qorpak Straight Sided Round Jars designed for?
Qorpak Straight-Sided Round Jars are designed to store analytical samples, high-purity chemicals, strong acids, solvents, and diagnostic reagents. Their clear flint glass construction allows easy visibility of contents, while the chemically resistant closure system helps maintain sample integrity in laboratory and chemical-processing environments.
What makes the straight-sided, no-shoulder design beneficial?
The no-shoulder, straight-sided design maximizes storage capacity and improves content visibility. This shape allows efficient filling and dispensing while enabling proper torque when securing the attached closure, helping ensure a consistent, reliable seal for laboratory and chemical storage applications.
What type of closure system do these jars use?
Qorpak Straight Sided Round Jars feature an attached green thermoset phenolic cap with a foam-backed PTFE liner. The thermoset closure offers broad chemical compatibility and high temperature tolerance, while the PTFE liner system provides strong chemical resistance and sealing performance.
How does the PTFE liner protect stored contents?
The foam-backed PTFE liner resists attack from virtually all chemicals at room temperature. Its layered construction includes a low-density foam core between polyethylene layers, helping maintain a tight seal while offering low moisture transmission and strong compatibility with aggressive substances.
Are these jars suitable for demanding laboratory environments?
Yes, Qorpak Straight-Sided Round Jars are commonly used in analytical laboratories, pharmaceutical settings, environmental testing, and chemical processing. Their chemically resistant closure system, durable glass construction, and secure sealing design support reliable storage of sensitive and reactive materials.
