1. Beaker clamp - made from high quality iron material, resistant to rust and deformation, easy to adjust, suitable as a reagent glass clamp. 2. Woodworking tools - for securing condensation tubes or retort stands and marble titration tables, adjustable jaw clamp. 3. Reagent glass clamp - compared to a two-jaw clamp, the three-jaw clamp is more stable and safer in use; lab stand clamp. 4. Lab clamp - suitable for holding small beakers, small cylindrical glass tubes, test tubes, condensers and more; lab clamp with serrated jaw. Use scenarios - In a distillation or titration setup, use the three-jaw reagent glass clamp to securely hold small beakers or glassware on a lab stand, preventing slips during heating or measurement. - For educational demonstrations, clamp small beakers, test tubes, or other glassware to a stand, ensuring stable positioning and easy visibility for students. - In a workshop or research environment, attach condensation tubes or retort stands with the appropriate clamp to maintain alignment and reliability during experiments.
