Reagent Bottle with Screw Neck

Superior Chemical Integrity & Optical Clarity

Osmosis Scientific Reagent Bottles are engineered for the high-integrity storage of aggressive reagents, volatile solvents, and sensitive biological media. Unlike standard soda-lime glass, our Type I Borosilicate 3.3 construction ensures a low linear expansion coefficient (3.3 × 10⁻⁶ K⁻¹), providing unmatched resistance to thermal shock and chemical leaching. This inert surface prevents pH shifts, ensuring your solutions remain stable during long-term storage.

Ergonomic Safety & GL 45 Standardization

We prioritize laboratory safety through functional design. Every bottle is equipped with:

• GL 45 Polypropylene Cap: A standardized, leak-proof screw neck compatible with most laboratory dispensing systems.
• Drip-Free Pouring Ring: Prevents hazardous chemical run-off, protecting the user and preventing benchtop contamination.
• Sloping Shoulder Design: Optimized for a smooth, consistent liquid flow during high-precision pouring.
• Permanent Graduations: High-contrast white enamel markings for easy volume assessment and a large marking spot for reliable sample identification.

Technical Specifications & Compliance

To ensure traceability and performance in regulated QC/QA environments, our glassware adheres to international metrology standards:

• Material: Borosilicate 3.3 (High-purity glass)
• Compliance: Fully compliant with ISO 4796-1 and IS 1388.
• Thermal Limits: Heat resistant up to 500°C; Autoclavable at 121°C.
• Range: Available from 25ml to 20,000ml (including Amber glass variants for UV-sensitive media).

Applications Across Industries

• Pharmaceutical R&D: Ideal for preparing standard solutions and buffer storage.
• Media Preparation: Built to withstand repeated autoclave sterilization cycles without clouding or “frosting.”
• Industrial Testing: Resistant to organic solvents, strong acids, and alkalis.
