What Is a Utility Clamp?
Science, and especially chemistry, can be a daunting undertaking for even the most well-prepared student. Learning the chemical names for common compounds, understanding scientific notation and learning the laboratory jargon are all part of the learning experience. Knowing what a "utility clamp" is as well as its function is of one of the most basic requirements of any laboratory experiment.

Identification
-
A utility clamp is composed of two pieces: a long "arm" piece with a C-shaped clamp on one end where it is attached to a surface to hold it steady and a slightly curved portion on the other end; the second piece attaches near the curved portion of the longer arm, where it can be tightened by a screw to come closer to the long arm and thus "clamp down" on the item it is holding.
Function
-
The function of the utility clamp is to hold certain size chemistry items in place: erlenmeyer flasks or test tubes, for example. The C-shaped section is meant to be clamped upon an upright metal rod but can also be clamped onto benches, tables or other steady surfaces providing the clamping surface fits within the C portion.

Time Frame
-
Utility clamps have been in use for as long as humans have been distilling chemicals, which is to say for hundreds of years. The older versions were not very uniform in appearance and varied wildly from chemist to chemist. In the 19th century, when chemistry became increasingly uniform and standardized, utility clamps became similar to their appearance today; the utility clamp has changed little in more than 100 years.
Identification
-
There are several clamp-like devices used in a chemical laboratory, including test tube holders, extension clamps and crucible tongs. Of these, only the utility clamp has both an end to hold flasks and other glassware as well as an end to attach to a stand or other surface.
Benefits
-
The benefit to using a utility clamp is steadiness, resistance to chemical hazards and portability. Unlike human hands, very little movement is found when a glass vial or beaker is clamped into place with a utility clamp. Also, utility clamps are not harmed by extremes in temperature, chemical burns or other hazards that can occur in the laboratory. Finally, because of its C-shaped clamp end, the utility clamp can be put on virtually any surface in order to hold cords, tubes or other material in a steady position for an indefinite period of time.
