60ml/125ml/250ml Glass Small Mouth Reagent Bottle with Ground Stopper Lab Sample Vials Narrow Mouth Reagent Bottle Lab Glassware

Core Product Value

A laboratory-grade storage container designed specifically for photosensitive chemicals, available in multiple capacities including 60ml, 125ml, and 500ml. Made of dark brown soda-lime glass, it provides a triple protective barrier:

Optical Protection: Effectively filters out ultraviolet light (wavelengths below 450 nm) to prevent photolysis of light-sensitive substances

Sealing Protection: The frosted glass stopper and narrow-mouth design ensure an airtight seal, preventing volatilization and leakage

Chemical Protection: Resistant to corrosion from strong acids and alkalis (pH range 1–14), ensuring the purity of the contents

​

Key Performance Advantages:

Light Stability Assurance

Light transmittance is strictly controlled at a low level (<10% at 380 nm), significantly extending the shelf life of light-sensitive substances such as vitamin B12 and silver nitrate

Operational Safety Design

Reinforced neck structure prevents accidental breakage

Liquid drainage channels ensure residue-free pouring

Wide temperature tolerance verified through rigorous thermal shock testing

Compliant Manufacturing

Complies with international laboratory glassware standards (ISO 4796); each batch includes certification for heavy metal leaching testing (Pb/Cd content below safety limits)
