Thermo Scientific Media Bottle PETG 60 ml Square 24 Bottles

Thermo Scientific Nalgene 2019-0060 Square Media Bottle – 60 mL, PETG, Sterile

The Thermo Scientific Nalgene 2019-0060 is a premium, ready-to-use 60 mL square media bottle engineered to completely eliminate the costly and time-consuming steps of in-house washing, depyrogenation, and autoclaving. Molded from highly durable, break-resistant Polyethylene Terephthalate Glycol (PETG), this transparent bottle offers excellent gas barrier properties, reducing the permeability of CO₂ and O₂ to maintain the pH of sensitive culture media. It is fitted with a 24-415 white high-density polyethylene (HDPE) screw closure and features a heat-shrink band around the neck to guarantee a tamper-evident seal. Certified sterile, non-cytotoxic, and non-pyrogenic, it is an essential primary containment vessel for the secure storage and transport of active pharmaceutical ingredients (APIs), biological buffers, and bulk intermediates.

Technical Performance and Design

• Durable PETG Construction: The heavy-walled, high-tensile PETG resin provides glass-like clarity while offering superior impact resistance, preventing catastrophic shattering in busy laboratories and cold-chain logistics.

• Tamper-Evident Closure: Features a precision-molded 24 mm HDPE screw cap secured with a heat-shrink band, providing a guaranteed leakproof seal and visual proof of product integrity prior to use.

• Space-Saving Square Profile: The square geometry maximizes valuable shelf space inside crowded incubators, refrigerators, and ultra-low temperature freezers, safely protecting samples down to -40°C.

• Certified Purity Profile: Manufactured in highly controlled cleanroom environments, the bottles are gamma-irradiated to a Sterility Assurance Level (SAL) of 10^-6 and comply with strict USP Class VI guidelines.

Key Benefits & Applications

• Biopharmaceutical Manufacturing: Serves as a ready-to-use containment solution that completely bypasses the labor-intensive need to wash, sterilize, and validate heavy glass bottles in-house.

• Cold-Chain Storage: The ideal vessel for the freezing and transport of sensitive biological materials, reliably withstanding prolonged low temperatures without the plastic turning brittle.

• Space Optimization: The square footprint dramatically reduces wasted negative space, allowing facilities to pack significantly more volume into expensive cold-storage infrastructure compared to traditional round bottles.

• pH Sensitive Liquids: The specialized PETG material offers exceptionally low gas permeability, protecting valuable buffered solutions and cell culture media from environmental pH shifts.
