Laboratory clamps for beakers, flasks, and tubes — extended-length beaker clamp, lightweight three-jaw clamp, and secure tube clamps. Key benefits Extended-length beaker clamp: longer reach makes it easier to position and secure flasks or test tubes, improving access during experiments and reducing awkward handling. Three-jaw clamp: lightweight and reasonably sized for easy carrying and compact storage; three jaws provide stable, even pressure on round or irregular glassware. Tube clamps: provide strong clamping force so items stay firmly fixed and are less likely to slip or fall during use. Durable laboratory construction: designed for routine lab use and reliable performance across common bench applications. Important attributes Function: holds beakers, flasks and test tubes securely for heating, titration, filtration and general manipulation. Compatibility: suitable for standard laboratory glassware and tubing; three-jaw design adapts to different shapes while tube clamps grip narrow items. Size and weight: extended length for reach; three-jaw clamp is lightweight and compact for convenient transport and storage. Performance: firm, stable clamping force to minimize movement and maintain sample integrity during experiments. Practical use scenarios Titration or heating: use the extended-length beaker clamp to position a flask over a hotplate or Bunsen burner while keeping hands clear of heat. Filtration setup: secure a funnel or filter flask with the three-jaw clamp for steady, leak-free filtration. Tube handling: hold test tubes or small-diameter tubing firmly in place during sampling, reagent addition, or when connecting tubing assemblies. Usage tips Ensure the clamp is securely fastened to the support rod or stand before placing glassware in the jaws. Adjust the jaw position so pressure is even and glassware is supported at multiple contact points. Check clamping force periodically during long procedures to maintain a secure hold. This configuration provides practical, reliable clamping options for routine laboratory tasks where reach, portability, and secure fixation are required.
