Factory Directly Supply 4ml Vials for Chromatography Needs

Jan. 9th, 2020
These standard opening screw thread 4ml Vials have a narrow opening that can be used with an 8-425mm cap and a septum. Designed to work with most autosamplers that require a thin vial neck and consists of type I borosilicate glass.
Automatic sample 4ml Vials are available in a variety of neck finishes and opening diameters. Large mouths or wide ID vials have about 40% wider mouths than standard opening vials. The large opening reduces the risk of the autosampler needle bending during sampling.
If the amount of samples is limited, consider using inserts for chromatographic vials.4ml Vials inserts come in a variety of shapes and sizes. A conical insert with a plastic spring at the bottom is recommended because the spring guarantees a seal with a vial cap liner.
Caps for threaded 4ml Vials can be used either in open holes for the use of autosamplers and standard additions, or at the solid top for sample storage. One-piece polypropylene caps and membranes are also available. These penetrating thread caps are designed for use once and there are no caps and seals to assemble, reducing sample preparation time.
