what is the use of tongs in laboratory
Tongs in a laboratory are used to safely hold and move hot or hazardous equipment —so your hands never have to go near the heat or chemicals.
Main uses of tongs in a laboratory
- Holding hot glassware like beakers, test tubes, and flasks while heating or after heating.
- Transferring hot crucibles, evaporating dishes, and metal containers from a Bunsen burner, hot plate, or furnace.
- Keeping hands away from corrosive, contaminated, or otherwise unsafe materials during handling.
- Providing a firm grip on smooth, slippery, or small lab items that are hard to hold with fingers, especially when they are hot.
Types of lab tongs (quick view)
| Type of tongs | Main use in lab |
|---|---|
| Crucible tongs | Grasping and moving hot crucibles, small beakers, and evaporating dishes. | [1][3][7]
| Beaker tongs | Holding and lifting hot beakers, often with rubber-coated ends for better grip. | [3][5][1]
| Test tube tongs (or holders) | Holding test tubes while heating them over a flame or in a water bath. | [9][1]
| Utility / general tongs | Multi-purpose handling of various hot or potentially hazardous lab items. | [5][6][3]
Why they matter for safety
- They reduce the risk of burns by keeping your hands away from hot equipment and flames.
- They help prevent spills of hot liquids or reactive substances by giving a controlled grip.
- They lower contamination risk, since you avoid touching samples and containers directly.
A simple way to remember: whenever something in the lab is too hot, too dangerous, or too awkward to hold by hand , you use tongs.
