Built for laboratory and chemical handling, our reagent bottles feature easy‑to‑read graduation marks and screw closures that secure reliably during storage and transport. Available in 50, 100, 500 and 1000 ml, the containers are produced in clear for visibility and amber for light‑sensitive media. Caps can be paired with appropriate liners to improve chemical compatibility and vapor control; neck and thread precision supports repeatable torque values and leak testing. We monitor glass integrity to reduce inclusions and ensure smooth inner walls for rinsing. Optional lot documentation and dimensional reports are available for incoming QC. Packaging uses molded pulp or foam cradles for larger sizes and tight‑fit partitions for smaller formats, helping printed scales remain crisp and legible on arrival.
