Product Description

The 50ml straight round bottom vial with white cross cover vials is designed for precise laboratory sample storage, featuring a uniform 50ml capacity and a leak-proof white polypropylene cross cap for secure sealing. Each pack contains 50pcs laboratory sample vials compatible with standard autosamplers, GC/HPLC systems, and centrifuge modules. Constructed from borosilicate glass, these vials withstand temperatures from -20°C to 121°C, ideal for chemical, pharmaceutical, and biotech applications. The straight round bottom design ensures stability during analysis, while the 33mm diameter matches industry-standard racks. Though optimized for small-volume samples, the limited capacity may require frequent refills for large-scale studies. The vials lack integrated electronics, focusing instead on chemical resistance and reusable functionality.
