Thermo Scientific Rapid Flow Filter Unit Receiver Bottle 1000 ml Case of 12 Bottles

Thermo Scientific Nalgene Rapid-Flow 1000 mL Filter Unit Receiver Bottles, Sterile (455-1000) – Case of 12

The Thermo Scientific Nalgene 1000 mL Rapid-Flow Receiver Bottles (455-1000) are high-purity, optical-grade polystyrene storage containers engineered to accept Nalgene Rapid-Flow vacuum filtration upper collars as well as serve as sterile media storage vessels. Precision-molded from clear, heavy-duty polystyrene, these 1000 mL receiver bottles feature ergonomic side indentations for secure handling with gloved hands inside biosafety hoods. Outfitted with leakproof 45 mm high-density polyethylene (HDPE) screw closures, these bottles maintain absolute vacuum seal integrity during filtration and provide safe long-term liquid storage. Supplied as a case of 12 sterile, individually wrapped bottles, this product line delivers certified non-pyrogenic and non-cytotoxic performance for tissue culture media preparation, biological buffer storage, and sterile fluid archiving.

Technical Performance & Structural Design

• Heavy-Duty Polystyrene Construction: Extruded from optical-grade virgin polystyrene to provide clear visual monitoring of filtrate clarity, volume levels, and phase boundaries.
• 45 mm Neck Thread Standard: Engineered with a standard 45 mm thread finish, ensuring direct compatibility with Nalgene 45 mm Rapid-Flow filtration tops, bottle-top filters, and standard transfer caps.
• Ergonomic Hand Grips: Molded with recessed side hand grips that provide firm control and minimize slip risks when handling full 1-liter volumes inside laminar flow hoods.
• Leakproof HDPE Screw Cap: Includes a blue 45 mm high-density polyethylene closure designed to form a liquid-tight seal that prevents evaporative loss and ambient contamination.
• Stable Wide-Base Profile: Designed with a low-center-of-gravity square/rounded footprint that prevents accidental tipping on laboratory benches during vacuum filtration setups.
