Amber borosilicate glass vials with solid-top closures. The black phenolic cap has a 14B white rubber liner. Both cap and liner are autoclavable and have substantial resistance to chemicals, acids and bases. This combination is ideal for general aqueous sampling needs without the added cost of Teflon®.

These sample vials are economically priced and conveniently packed in two shrink-wrapped packs of 100 vials. This packaging reduces contamination from corrugated material found in more traditional packaging. The vials and caps are packaged separately.
**14B white rubber is white styrene-butadiene rubber.
