Adapters, Rotary Evaporators, Vials

Adapters allow direct connection of standard laboratory dram sample vials to the vapor tube or bump trap of a rotary evaporator. Each adapter features a top outer joint (as listed) and a 20-400 G.P.I. threaded bottom. A PTFE-lined, phenolic, double-threaded connector securely attaches the vial to the adapter.
