QEC offers two lines of premium leak-proof plastic containers that are ideal for sampling sludge, oil, and water for metals, or for any applications where container security is critical.
Q-Seal™ HDPE oblongs are a precision-sealing mated container-closures system designed for single use without sacrificing leak-proof reliability.
UltraLab™ HDPE and polypropylene rigid plastic containers, like Q-Seal, are constructed of top-quality resins and undergo rigorous design inspections and testing. Engineered to withstand excessive vibration and eliminate closure back-off during shipping. Closures are molded polypropylene for excellent chemical resistance.
