Drying Tubes, Straight with Single Joint

Item #: CG-1293

Normal Availability: 1-3 business days

Product Description

These vertical drying tubes have a beaded top rim and your choice of 14/20 or 19/22 lower inner joint. In typical use, one places a small wad of glass wool into the bottom of the tube, fills the tube with a desiccant such as calcium chloride, and then places a one-hole rubber stopper with a glass inlet tube on the top (not included). A classic piece of organic synthesis equipment!

Both versions feature an overall length of 130 mm, tube diameter of 16 mm and 1.8 mm walls. See item # CG-1295 and CG-1296  for versions that include a rubber stopper and glass inlet tube.
