Fisher Scientific Glass Vial 20 x 150 mm Borosilicate Glass Screw Neck 500 Vials

Fisher Scientific 20 x 150 mm Borosilicate Glass Vials (Screw Neck)

The Fisher Scientific 20 x 150 mm vial is a heavy-duty laboratory storage and culture vessel engineered for maximum durability and chemical purity. Manufactured from Type I, Class A borosilicate glass, these vials offer exceptional resistance to thermal shock and chemical leaching, making them ideal for the long-term storage of volatile reagents, acids, and biological media. The 150 mm length provides a generous working volume for large-scale samples, while the precision-machined screw neck ensures a secure, airtight closure when used with compatible caps. Designed to withstand the rigors of autoclaving and centrifugation, these vials are a versatile staple in analytical chemistry, microbiology, and clinical research laboratories.

Technical Performance and Design

• Type I Borosilicate Glass: Constructed from low-expansion glass that minimizes pH changes and prevents the leaching of free alkali, ensuring the stability of sensitive chemical and biological samples.

• Thermal Shock Resistance: Engineered to withstand rapid temperature transitions, allowing for safe movement between cold storage and boiling water baths or autoclaves.

• Precision Screw Thread Finish: Features a standardized screw neck designed to interface perfectly with phenolic or polypropylene caps, providing a leak-proof seal for volatile liquid transport.

• High Clarity and Durability: The uniform wall thickness provides superior mechanical strength and optical clarity, facilitating easy visual inspection of sample precipitates or cell growth.
