SKS Amber Glass Vial 2 ml Screw Neck Sealed 100 Vials

The SKS Science (Catalog 40600003.01S) Amber Glass Vial is a compact, high-performance storage solution designed for handling light-sensitive samples in laboratory and industrial settings. This specific vial has a capacity of 1/3 dram (approximately 1.2 mL to 2 mL depending on fill level) and is manufactured from Type I Borosilicate Glass. This glass type is the gold standard for laboratory use because it is chemically inert and has a high resistance to thermal shock, ensuring that the vial will not leach contaminants into your samples or crack during temperature fluctuations. The amber tint is not a surface coating but is integrated into the glass itself, effectively filtering out ultraviolet (UV) and visible light in the 300–500 nm range to prevent the photodegradation of sensitive compounds like vitamins, enzymes, or reagents.

The vial is designed with a 13/425 neck finish, which is a standard screw-thread size that allows for a wide variety of closure options. Because this specific catalog number is typically sold as "Bulk (Caps Not Included)," it allows researchers to select the exact closure system required for their application, whether that be a standard phenolic cap, a cone-lined cap for a superior liquid seal, or a dropper tip for controlled dispensing. The vials are supplied in shrink-wrapped case packs (typically 144 per case), a packaging method chosen specifically to eliminate the "corrugated dust" and particulates commonly found in traditional cardboard-partitioned boxes. This ensures the vials arrive in a cleaner state, reducing the time required for pre-analytical preparation.
