These tags were designed to simplify labeling of volumetric flasks. No longer is it necessary to use labeling tapes or stickers. With these tags, simply write the information on the tag and attach the tag to the neck of the flask by slipping the opening of the tag over the neck of the flask. Once the tag is attached to the flask, the tag can be moved and positioned anywhere on the neck of the flask. In addition, the tag’s position can be “locked” by flipping the upper tab downward. Locking the tag can be most useful during sample sonication when it is desirable to lock the tag in a position above the water bath. Removing the tag during cleanup is just as easy. Simply lift the tag up over the neck of the flask and discard the used tag. No more peeling tapes or stickers. Using these tags eliminates the hassle of cleaning glue residue left behind by tapes and stickers.
The labeling tags come in varying sizes to accommodate commonly used flask sizes. Added color makings on the tag allow for quick identification of tag size.
