Nalgene
Thermo Scientific Nalgene carboys and jerricans are engineered as superior containers to maximize product security for vaccines and biologics, manufactured from high-quality resins under rigorous production standards. These shatter-resistant, leakproof containers are offered in diverse materials, each optimized for specific applications: Polycarbonate (PC) provides crystal-clear visibility, autoclavability, and suitability for ultra-low temperature storage, serving as a safer alternative to glass where full content visualization is required; High Density Polyethylene (HDPE) boasts excellent chemical compatibility, pre-sterilized/single-use options, and is ideal for harsh conditions and a wide temperature range (-100°C to +120°C), making it suitable for media formulation and mixing; Polypropylene (PP) is perfect for in-house cleaning, autoclaving, heavy-duty vacuum applications, and includes options with sanitary dispensing ports and TPE gaskets for leakproof seals, often used as supply reservoirs; and Low Density Polyethylene (LDPE) is designed for general laboratory use and stirring intermediates. Technical details emphasize a guaranteed leakproof design, rigorously verified through specific testing protocols (e.g., 2 psig pressure for closures under 100mm, inversion for larger ones). Comprehensive forced extraction and leachables studies are conducted using various solvents (water, ethanol, hexanes, nitric acid) and analytical methods (GC/MS, LC/MS, ICP) to identify potential compounds, ensuring product integrity and regulatory compliance. Nalgene products adhere to strict regulatory compliance, including ISO 13485, GMP Class I, and utilize DMF-registered, USP Class VI compliant resins, supported by full traceability, quality control, and customer documentation. The catalog also highlights Top Works aseptic fluid handling systems, featuring platinum-cured silicone stopper inserts and tubing, enabling secure and sterile liquid transfer for critical biopharmaceutical applications.
