Microscale, thin-wall reaction vial.

The top joint is a combination cap, thread and joint to accommodate and seal other microscale apparatus. The Ext.Ø of the top joint has an external thread to facilitate an O-ring and open-top phenolic cap. The internal or Int.Ø at the top is a ground standard taper 14/10 outer joint. This thin-walled vial has better heat transfer for the more demanding research project. Vials with side ports are supplied with holed cap and septum that facilitates syringe retrieval or injection for the port.
