Glass Screw Top Vials with Phenolic Polycone Caps
Also known as sample vials, these screw top glass vials come packed and sold in shrink wrapped trays to ensure vials have no outside contaminants. Phenolic polycone lined caps included. Phenolic caps are chemically inert, have a high heat tolerance and are commonly used in laboratories for their durability and safety. The included polycone liner virtually eliminates leakage, evaporation, contamination, binding and backing off.
