Thermo Scientific Nalgene 2019-0030 Media Bottle – 30 mL, PETG, Square, Sterile

The Thermo Scientific Nalgene 2019-0030 is a high-performance, 30 mL storage bottle engineered for the rigorous demands of biopharmaceutical manufacturing and laboratory liquid handling. Constructed from premium, glass-clear PETG, this bottle offers a drastically reduced permeability to CO2 and O2 compared to standard plastics, ensuring that highly sensitive biological buffers and culture media maintain their optimal pH over prolonged storage periods. Designed to replace fragile and heavy glass media bottles, the 2019-0030 eliminates the costly and time-consuming steps of in-house washing, depyrogenation, and autoclaving. Each bottle is certified radiation-sterilized (SAL 10^-6), non-cytotoxic, and non-pyrogenic out of the box. Capped with a secure 20 mm HDPE closure and a tamper-evident neck band, it is the ideal vessel for securely storing and transporting active pharmaceutical ingredients (APIs), frozen intermediates, and critical diagnostic reagents.

Technical Performance and Design

• Break-Resistant PETG Construction: Unlike traditional borosilicate glass, the PETG polymer is virtually unbreakable, drastically reducing the risk of catastrophic sample loss while maintaining excellent optical clarity for visual fluid inspections.

• Space-Saving Square Geometry: The ergonomic square profile maximizes valuable shelf and incubator space, allowing researchers to efficiently pack more bottles into a smaller footprint compared to traditional round bottles.

• Leakproof HDPE Closure: The 20 mm white HDPE screw cap features Nalgene's signature linerless, leakproof sealing ring, completely preventing fluid bypass during rigorous transit or orbital shaking.

• Sterile & Tamper-Evident: Each bottle is secured with a tightly fitted heat-shrink band around the neck and cap, providing immediate visual confirmation that the sterile internal environment has not been compromised.

Key Benefits & Applications

• Media & Buffer Storage: The low gas permeability of the PETG resin maintains strict pH stability, making it perfect for the long-term storage of sensitive tissue culture media and biological serums.

• Bioprocessing & APIs: The universally trusted vessel for the secure sampling, storage, and cold-chain transport of high-value active pharmaceutical ingredients and bulk intermediates.

• Cold-Chain Logistics: Specifically validated to withstand freezing down to -40°C without the plastic turning brittle, cracking, or the cap seal failing.

• Ready-to-Use Efficiency: Bypasses tedious prep steps; researchers can immediately unwrap the tray and begin sterile aliquoting inside a biological safety cabinet.
