snap top vials

Aijiren’s Snap Top Chromatography Vials are made of transparent or amber type 1 borosilicate glass (Grade A, 33 expanded borosilicate glass). The Snap Top Chromatography Vial can accept either aluminum snap-on seals or polyethylene snap-on caps. The colors are white, red, and blue. You can choose from them, which is very suitable for short-term storage.

Snap Cap Vials are an extension of the crimp cap system of sealing. A plastic cap is stretched over the rim of the vial to form a seal by squeezing the septum between the glass and the stretched plastic cap. Plastic has memory and wants to return to the original dimension. This tension in the cap to return to its original size is the force forming the seal between glass, cap and septum. The advantage of a plastic snap cap is no tools are required to assemble. The snap-top cap is a compromise sealing system.
