Thermo Scientific Nalgene Media Bottle 125 ml PETG Square Sterile Pack of 24

Nalgene 342020-0125 Square Media Bottle – 125 mL, PETG, Sterile, 38-430 Cap

The Nalgene 342020-0125 is a high-performance 125 mL media bottle designed for the secure storage and transport of sensitive biological fluids, culture media, and reagents. Constructed from high-clarity, medical-grade PETG, this bottle provides a robust, shatterproof alternative to glass while offering excellent gas barrier properties to minimize pH shifts in buffered solutions. The square footprint is specifically engineered to maximize storage efficiency in laboratory incubators and refrigerators. Supplied sterile and non-pyrogenic, each bottle features a leak-proof 38-430 screw closure, ensuring the integrity of high-value samples during both short-term storage and long-distance shipping.

Technical Performance and Design

• Superior Gas Barrier Properties: PETG construction significantly reduces the permeability of oxygen and carbon dioxide, helping to maintain the stability and pH levels of sensitive media and buffers.

• Space-Saving Square Design: The square geometry allows for more efficient use of shelf space and prevents rolling, making it ideal for high-density storage and automated filling lines.

• Leak-Proof 38-430 Closure: The linerless high-density polyethylene (HDPE) cap is precision-molded to provide a secure seal without the risk of contamination from liner materials.

• High Clarity & Durability: Provides excellent optical transparency for easy visual inspection of contents, combined with the impact resistance necessary to withstand freezing and rigorous handling.
