Merck, Z167061-1EA, ACE microscale, fixed-head, spinning-band column assembly

General description
Effective for separating low-boiling liquid mixtures with volumes in the 0.5 to 5.0 mL range. Low cost makes it useful for teaching microdistillation. Column has screw-threaded 14/10F joint at top and 14/10M joint at bottom with screw-threaded 7/10M joint on drip-tipped take-off arm. Body is vacuum jacketed. Band is virgin PTFE with permanently attached "V" bottom magnet. Coupled to a conventional magnetic stirrer, experimental data indicate satisfactory performance at 1000 rpm. Column has been shown to achieve height-equivalent theoretical-plate (HETP) values approaching 0.2 in./plate within 90 min. of reaching distillation temperature.
