Product Description

The 50ml straight round bottom bottle with transparent screw cap vials is designed for precise liquid handling in laboratory settings. Constructed from borosilicate glass, these 50ml laboratory screw caps feature chemical-resistant threads and leak-proof PTFE/silicone septa, ensuring compatibility with aggressive solvents. The cylindrical shape optimizes storage density, while the clear design enables visual monitoring of contents. Operating temperature ranges from -80°C to 200°C, suitable for autoclaving and freeze-storage applications. These vials integrate seamlessly with automated sample handling systems through standardized 33-430 thread specifications. Widely used in pharmaceutical quality control, analytical chemistry, and biotech research, their 43mm diameter base ensures stability on various lab platforms. Key advantages include superior optical clarity and enhanced pressure resistance, though the rigid design limits flexibility for cryogenic grinding. Screw caps maintain 12-15 in-lbs torque retention for secure sealing.
