These are a must have if you are using beakers over an open flame. They provide a rubber clamp that secures the beaker in place and keeps you from getting burned by having your hands too close to the burner! Great!
Tongs very useful/safer
I usually never look in the catalog for items, only online. This time I decided to browse the catalog. I wish I had ordered these tongs a long time ago. They are excellent for picking up hot beakers. Previously I had been using regular tongs and pot holders purchased at local discount stores. The beaker tongs' shape make them safer to use and more efficient.
These tongs are great for working with beakers that have to be heated to boiling temperatures. They make holding the beaker much easier than trying to use a hot pad because, with these, you can pour the contents easily and safely. The only "problem" I have had with them is when we used them to remove a crucible from a fire below it. The crucible was extremely hot and melted a little bit of the rubber from one of the arms of the tongs. This is not what these were meant for, but we forgot our regular tongs. When used correctly, you should have no problem with them. Even with the slight melting, they are still very usable today.
Use beaker tongs to handle hot beakers. These nickel-plated steel tongs are 25 cm (10") long and have plastic coated jaws that open up to 11 cm (4.5"). They can hold beakers ranging from 100 ml up to 1000 ml.
