QORPAK 235281 Amber Glass Serum Vial, 20 mm Screw Thread, Square Bottom

The QORPAK Borosilicate Serum Vial is used for storing and transporting liquid pharmaceutical or laboratory samples. Its amber body protects light-sensitive contents, and the self-standing square bottom allows stable placement on work surfaces. It is supplied without a closure, so you must source a compatible 20 mm screw cap separately.

This 10 mL vial has a 27.75 mm body diameter, amber borosilicate glass, a square self-standing bottom, and a 20 mm screw closure size. It is supplied without a closure and carries manufacturer part number 235281. The amber color provides UV protection for light-sensitive contents.

You can source the QORPAK Borosilicate Serum Vial through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this vial without a closure as specified.

Select a 20 mm screw closure that matches the vial's neck finish. Since the vial is supplied without a closure, ensure the cap material (e.g., polypropylene or aluminum) is compatible with your stored contents. For light-sensitive applications, consider an amber or opaque cap. Always verify the closure's seal integrity with the borosilicate glass.
