The 100 ml capacity permits sufficient solvent capacity for the full extraction process.

The tube features a 24/40 standard taper outer joint, and is supplied with one Keck clamp. It is designed for use with the PYREX® accelerated one-step extractor/concentrator. The jacketed design permits circulation of hot water through the jacket to boil the solvent during extraction/concentration. The bottom portion of the tube is never heated, so the sample won't boil dry. Threaded tubulations on the water jacket have an I.D. of 8 mm.
