Thermo Scientific Square Bottle 1000 ml Narrow Mouth PC Case of 24 Bottles

Thermo Scientific Nalgene 2015-1000 Square Media Bottle – 1000 mL, Polycarbonate

The Thermo Scientific Nalgene 2015-1000 is a premium 1000 mL (1 Liter) square media bottle engineered for the secure preparation, short-term sampling, and long-term storage of critical biological reagents, cell culture media, serum, and aqueous buffers. Molded from high-purity, optically clear polycarbonate (PC), this shatterproof bottle combines glass-like visualization with the structural safety of an impact-resistant polymer. Featuring a space-saving square silhouette and a 38 mm narrow mouth, it is designed to maximize shelf and incubator capacity. The bottle arrives completely sterile and is equipped with a linerless high-density polyethylene (HDPE) screw closure that guarantees a leak-proof seal without the risk of chemical leaching.

Technical Performance and Design

• Optically Clear Polycarbonate: Provides exceptional clarity for immediate visual inspections of contents, color changes, or precipitation, while offering an extremely wide operational temperature range from -135°C to +135°C.

• Space-Saving Square Geometry: The architectural square shape allows bottles to pack tightly side-by-side, saving up to 13% more space on laboratory shelves, inside walk-in cold rooms, and within automated incubators compared to traditional round bottles.

• Linerless Leak-Proof Cap: The 38-430 mm HDPE screw closure interfaces seamlessly with the bottle’s molded neck threads. By eliminating a separate cap liner, it removes a common source of trace contamination, crevice-buildup, and fluid wicking.

• Molded Graduations & Neck Ring: Features permanent, easy-to-read molded-in volumetric graduations for rapid compounding approximations, along with an integrated neck ring optimized for secure manual handling or automated filling lines.

Key Benefits & Applications

• Biopharmaceutical & Media Archiving: The ideal standard for preparing and archiving bulk cell culture media, nutrient broths, fetal bovine serum (FBS), and sensitive biological matrices.

• Cryogenic Cold Storage: Due to the resilient properties of polycarbonate down to -135°C, these bottles are routinely utilized for freezing and long-term storage of valuable active pharmaceutical ingredients (APIs).

• Shatterproof Glass Replacement: Eliminates the extreme physical hazard of glass breakage and liquid spillages in busy processing rooms or cleanrooms, while matching the optical clarity that researchers expect from glass vessels.

• Autoclavable Material: While supplied pre-sterilized via gamma irradiation, the polycarbonate bottle housing itself can be repeatedly autoclaved in-house if required by standard operational procedures (note: caps must be fully loosened or removed during autoclaving).
