Qualitative Transfer Device for Volatile Liquids We have developed a simple, inexpensive, easily made device for qualitative transfer of low-boiling and/or very volatile liquids. The design arose from the problem of transferring small amounts of tetramethvlsilme into nmr samnle tubes (as an internal reference). TMS is
cools sufficiently so that, with some dexterity and speed, one usually manages to transfer some of the TMS into the narrow nmr tube. I t has been found that blowing a bem~sphericalbulb into the capillary, a t or near the paint where the capillary joins the pipet, largely eliminates the above mentioned problems, while bending the capillary part of the tube some 3045" makes filling of the transfer ninet, and the receiver. even more convenient. The device can also be used for transferring denser liquids, such as elemental bromine.
