Crimp neck vials and micro-vials ND8 are available in clear and amber first hydrolytic class glass. They can be sealed with 8 mm crimp caps, 9 mm PE caps or 8 mm push-on caps. The micro-vials often require an adapter so that they can be used in an autosampler.

These vials are especially used with autosamplers made by Beckman, CTC, Gilson, Knauer, Shimadzu, Spark, Varian and VWR/Hitachi....
