Thermo Nalgene Media Bottle 250 ml PETG Square Case of 48

Thermo 2019-0250 Nalgene Media Bottle 250 ml PETG Square

The Thermo Scientific Nalgene 2019-0250 is a high-quality, 250 ml square media bottle designed for the storage and shipment of light-sensitive biological reagents, culture media, and buffers. Manufactured from durable, glass-clear PETG (Polyethylene Terephthalate Glycol), these bottles offer a shatterproof alternative to glass while maintaining excellent gas barrier properties. The square footprint is specifically engineered to maximize storage efficiency in laboratory refrigerators, incubators, and shipping containers.

Technical Performance and Design

• High-Purity PETG Construction: Provides excellent optical clarity for easy visual inspection of contents and is non-cytotoxic, non-pyrogenic, and non-hemolytic.

• Superior Gas Barrier: PETG minimizes the loss of CO2 and helps maintain the pH of stored media and buffers over extended periods.

• Leakproof Guarantee: Features a linerless, 38 mm white high-density polyethylene (HDPE) screw cap that provides a secure, leakproof seal without the risk of liner contamination.

• Square Space-Saving Design: The flat-sided geometry allows for dense packing on shelves and in storage racks, utilizing up to 20 percent more space than traditional round bottles.
