Thermo Nalgene Media Bottle 500 ml PETG Square Sterile Case of 24

Description

Thermo Scientific Nalgene 500 ml PETG Square Media Bottle (2019-0500)

The Thermo Scientific Nalgene 2019-0500 is a high-performance, 500 ml square media bottle specifically engineered for the secure storage and transport of sensitive biological reagents, culture media, and sera. Manufactured from medical-grade, USP Class VI PETG, this bottle provides exceptional optical clarity and a robust gas-barrier layer that prevents oxygen and CO2 permeability, ensuring the long-term pH stability of stored fluids. The unique square footprint maximizes storage efficiency in refrigerators and incubators, while the molded-in graduations allow for quick and accurate volume assessment. Delivered gamma-sterilized and certified non-pyrogenic, the 2019-0500 features a leak-proof 38-430 screw cap, making it the premier choice for laboratories that demand the highest levels of sample integrity and safety.

Technical Performance and Design

• Enhanced Gas Barrier Properties: PETG construction offers superior resistance to gas permeation compared to polystyrene or polyethylene, making it ideal for maintaining the integrity of pH-sensitive media and buffers.

• Shatter-Resistant Clarity: Combines the transparency of glass for easy sample inspection with the impact resistance of plastic, significantly reducing the risk of sample loss and injury from breakage.

• Guaranteed Leak-Proof Closure: The 38-430 linerless screw cap is engineered to provide a secure seal without the risk of contamination associated with cap liners, ensuring safe transport of hazardous or valuable biologicals.

• Space-Saving Square Design: The square geometry allows for high-density storage on laboratory shelves and in shipping containers, utilizing up to 20% more space than traditional round bottles.
