Thermo Scientific Square Bottle 1 L Polycarbonate Sterile 30 Bottles

Description

Thermo Scientific 3120-42 Square Bottle – 1 L, Polycarbonate, Autoclavable

The Thermo Scientific 3120-42 (Nalgene) is a high-performance 1 Liter (1000 mL) square laboratory bottle designed for the secure storage and transport of aqueous solutions, biological media, and high-purity reagents. Manufactured from medical-grade, crystal-clear polycarbonate, this bottle provides exceptional impact resistance and the optical transparency of glass, allowing for effortless visual monitoring of contents. The space-saving square geometry allows for a more efficient laboratory footprint, maximizing storage capacity in refrigerators, freezers, and incubators. Featuring a leak-proof 38-430 mm polypropylene screw closure, the 3120-42 is engineered to maintain a hermetic seal, protecting samples from contamination and evaporation. This bottle is fully autoclavable and rated for a wide temperature range, making it a versatile staple for molecular biology and cell culture workflows.

Technical Performance and Design

• Optical Clarity: The glass-clear polycarbonate construction provides an unobstructed view of sample volume, color, and precipitates without the risk of shattering associated with traditional borosilicate glass.

• Impact Resistance: Polycarbonate is one of the toughest laboratory plastics available, capable of withstanding drops and high-velocity centrifugation without cracking, even when frozen at -80°C.

• Leak-Proof 38-430 Closure: The precision-molded 38 mm polypropylene screw cap utilizes a linerless design to create a superior seal, ensuring that the bottle remains leak-proof during aggressive agitation or transit.

• Square Space-Saving Profile: The flat-sided design prevents rolling and allows bottles to be packed tightly together, occupying up to 20% less shelf space than round bottles of the same volume.
