Which device picks up and holds test tubes; the test tubes may be hot

• A. Test Tube Rack
• B. Swab
• C. Stirring Rod
• D. Stoddard Clamp Test Tube Holder

Answer: (D)

Handling hot glassware requires a tool that can grip the tube securely while keeping your hands away from heat. The Stoddard clamp test tube holder is designed to do just that: it attaches to a stand and clamps around a test tube so you can lift, move, or hold it in place during heating without direct contact. This reduces the risk of burns and helps keep the tube steady and less likely to tip or break. A test tube rack, while useful for organizing and transporting tubes, isn’t meant to grip or lift hot glass. A swab is for sampling or cleaning, not for holding tubes, and a stirring rod is for mixing, not for securing or transferring tubes.
