The Firestone Micro Rotary Evaporator is constructed of glass, PTFE, and nylon

A 2mm straight bore stopcock attaches to the drying tube and/or McLeod gauge. One arm of the double oblique stopcock attaches to a dry ice trap and vacuum line. The other arm is for easy vacuum release, and it can be connected to a trap. All of the glass components are fabricated from borosilicate glass.

It can be used with any lab stirring motor. The apparatus features a 10mm O.D. hollow glass tube/shaft with [ST] 14/20 inner joint at one end for connection to a flask, and holes drilled near the center for vacuum. The device attaches to a laboratory stirring motor via a chuck. The shaft/tube turns inside a PTFE bearing held in #15 Ace-Threds by a nylon bushing, compression saddle with O-Ring, and lock nut.
