Pipe tube clip - Provides a secure, stable grip on pipes and tubes to improve handling safety during use. Keeps setups steady and reduces risk of slips when working with crucibles or related components. Test tube clamps - Offers improved maneuverability and control for precise, repeatable experiments. Keeps test tubes steady during heating, mixing, or measurements in the lab. Tube clamp - Holds a variety of laboratory containers securely, including beakers and crucibles. Maintains stability during heating, transfers, and alignment in setups. Smelting tools - Essential for maintaining safety and precision in melting and high-temperature experiments. Enables controlled handling and positioning of hot vessels. Use scenarios - Melting or heating: clamp a crucible or beaker to prevent tipping and spills during high-temperature work. - Precise experiments: hold test tubes steady while adding reagents or monitoring reactions for accurate results. - Lab setup: secure multiple containers on a stand to keep experiments organized and stable during transfers and observations.
