Thermo Scientific Carboy 5 L Biocontainer Polycarbonate Lot of 4 Bottles

Thermo Scientific Nalgene 3405-16 Biotainer Carboy – 5 L, Polycarbonate, Sterile

The Thermo Scientific Nalgene 3405-16 is a sterile, ready-to-use 5-liter Biotainer carboy engineered to eliminate the costly and time-consuming steps of in-house cleaning, depyrogenation, and validation. Molded from durable, high-impact polycarbonate, this space-saving square container features an integrated handle to facilitate the secure handling and pouring of heavy, high-value fluids. It provides exceptional optical clarity for the visual inspection of contents and maintains structural integrity at extreme cold temperatures, safely protecting samples down to -100°C. The container is capped with a 48 mm polypropylene closure that utilizes a premium silicone liner to create a guaranteed leakproof barrier against environmental contaminants and fluid bypass. Certified sterile, non-cytotoxic, and non-pyrogenic, the 3405-16 is an essential primary containment vessel for demanding bioprocessing and cold-chain logistics applications.

Technical Performance and Design

• Durable Polycarbonate Construction: The high-tensile polycarbonate resin offers glass-like clarity while providing extreme impact resistance, preventing catastrophic shattering if accidentally dropped during transit or cold storage.

• Silicone-Lined Closure: The 48 mm screw cap features an internal silicone liner that compresses tightly against the bottle rim, ensuring a completely leakproof seal even when subjected to atmospheric pressure changes during air freight.

• Ergonomic Square Profile: The square geometry maximizes valuable shelf space inside crowded incubators and ultra-low temperature freezers, while the heavily reinforced molded handle ensures a secure grip for users wearing thick cryogenic gloves.

• Certified Purity Profile: Manufactured in heavily controlled cleanroom environments, the carboys meet strict USP Class VI and USP <661> standards, guaranteeing they are free of pyrogens and cytotoxic leachables.

Key Benefits & Applications

• Cryogenic Storage: The ideal vessel for the bulk freezing of sensitive biological materials, intermediates, and viral vectors, reliably withstanding freeze-thaw cycles without the plastic turning brittle.

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

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

• Risk Mitigation: The guaranteed leakproof, pre-sterilized format drastically reduces the risk of carryover contamination, simplifying critical compliance workflows in strict GMP and clinical environments.
