Thermo Scientific Bottle 1000 ml PETG Square 35 Bottles

Thermo Scientific 3110-35 Nalgene Biotainer – 1000 mL, PETG, Sterile, Square

The Thermo Scientific 3110-35 is a premium 1 Liter (1000 mL) Biotainer designed for the stringent requirements of the biopharmaceutical and biotechnology industries. Manufactured from high-quality, crystal-clear Polyethylene Terephthalate Glycol (PETG), this bottle provides an exceptional barrier against gas permeation (O2 and CO2), ensuring the pH stability and integrity of sensitive biological reagents. The space-saving square geometry maximizes storage efficiency in ultra-low temperature freezers and cold rooms. Each Biotainer is supplied sterile, pyrogen-free, and equipped with a 38 mm leak-proof screw closure featuring a silicone liner. Engineered to withstand temperatures as low as -70°C, the 3110-35 is the ideal vessel for the storage and transport of bulk drug substances, vaccines, and sterile media.

Technical Performance and Design

• Exceptional Gas Barrier: PETG construction offers superior resistance to gas transmission compared to other plastics, making it critical for maintaining the pH of carbonate-buffered media during long-term storage.

• Deep-Freeze Resilience: Formulated to maintain structural integrity and impact resistance at temperatures as low as -70°C, providing a safe solution for frozen bulk intermediates.

• Lined Leak-Proof Closure: The 38-430 mm screw cap includes a high-purity silicone liner that ensures a hermetic seal, preventing evaporation and protecting contents from external contaminants during transit.

• Sterile & Ready-to-Use: Certified sterile (SAL 10⁻⁶), non-pyrogenic, and non-cytotoxic, eliminating the need for in-house cleaning and validation before use in sensitive bioprocesses.
