Wheaton Amber Glass Vial 5 ml Crimp Neck 22 x 44 mm 143 Vials
Wheaton 223695 Serum / Crimp Vial – 5 mL, Amber Glass, 20 mm Crimp Neck
The Wheaton 223695 is a premium 5 mL amber glass vial engineered for the safe storage, lyophilization, and transport of light-sensitive biological and chemical samples. Manufactured from high-quality Type I borosilicate glass, these vials provide exceptional chemical resistance, ensuring that no ions or impurities leach into the stored solution. The amber coloring naturally filters out damaging ultraviolet (UV) and visible light in the 290 to 500 nm range, making it indispensable for photosensitive proteins, vitamins, and light-degrading reagents. Designed with a standard 20 mm crimp-top neck finish, these vials are intended to be securely closed with aluminum seals and rubber septa, creating a leak-proof, tamper-evident barrier for volatile substances or long-term cryogenic archiving.
Technical Performance and Design
Amber UV Protection: The dark amber glass effectively blocks harmful light wavelengths, safeguarding sensitive compounds from photo-degradation without the need for secondary foil wrapping.
Type I Borosilicate Glass: Provides a highly inert, non-reactive interior surface that minimizes pH shifts and prevents chemical interactions with aggressive solvents or concentrated acids.
20 mm Crimp Top Finish: The heavy-duty neck is designed to withstand the downward pressure of mechanical crimping tools, ensuring a tight, uniform seal that prevents evaporation and contamination.
Heavy-Wall Construction: Built to endure extreme temperature shifts, making these vials perfectly suited for lyophilization processes, autoclave sterilization, and deep-freeze (-80°C) storage.

Key Benefits & Applications
Lyophilization (Freeze-Drying): The go-to vessel for producing freeze-dried biologics, allowing for a slotted rubber stopper to vent moisture before being fully seated and crimped under a vacuum.
Sample Archiving: The crimped aluminum seal guarantees sample integrity, providing clear tamper evidence for banked sera, antibodies, and reference standards.
Light-Sensitive Reagents: Essential for the storage of photo-reactive chromatography standards, vitamins, and specialized pharmaceuticals.
High-Throughput Automation: The standard 22 x 44 mm footprint ensures compatibility with a wide range of automated liquid handlers, autosamplers, and robotic crimping machines.
