HDPE Screw Cap Cylindrical Jars

Molded from high-density polyethylene (HDPE), these wide-neck jars feature a smooth, cylindrical profile that allows easy spoon sampling, complete spatulation, and unhindered recovery of dense or viscous materials. Each jar includes a protective inner sealing disc/insert underneath the threaded screw cap, creating a tight physical seal that protects moisture-sensitive powders from ambient humidity and guards against liquid seepage during transport.

Key Functional Benefits:

• Wide-Mouth Open Neck: Expansive neck diameter permits effortless insertion of large spatulas, scoops, and large solid specimens without clogging or powder bridges
• Dual-Closure Sealing Protection: Supplied complete with an internal drop-in sealing insert disc and a threaded exterior screw cap to maintain a moisture-proof seal
• Chemical & Impact Resistance: High-density polyethylene (HDPE) construction resists impact, cold-room embrittlement, and attack from inorganic acids, alkalis, and aqueous solutions
• Straight-Cylindrical Geometry: Flush interior walls eliminate internal shoulders and crevices, ensuring complete product recovery and easy cleaning between uses
• Scalable Storage Capacity: Available in seven capacities ranging from 70 mL benchtop jars up to 2000 mL bulk storage vessels to suit any sample volume requirement
