- Good handling with gloves
- Quick assembly
ND13 screw neck vials are constructed from type I borosilicate glass with low metal content. Vials are available in amber or clear versions with a flat bottom to ensure compatibility with inserts. Associated screw caps, mostly available with assembled septa, are engineered to prevent sample contamination while providing consistent, secure seals. The use of closed caps allows the samples to be stored for a long time (long-term storage applications).
