- High quality metal material: the 3-prong piston clamp is made of durable metal with a robust die-cast construction, delivering a long service life and the ability to withstand the rigors of laboratory use. - Adjustable design: the adjustable rotary clamp base can be easily and securely attached to the edge of a desk or laboratory work area, providing a stable and reliable hold for your laboratory equipment. - No scratches: the swivel clamp has plastic coated tips that leave no scratches on objects, helping keep glassware and devices in pristine condition. - Wide use: the rubber coating rotary clamp can safely hold a variety of items such as pistons, test tubes, capacitors, and more, making it an indispensable tool for many laboratory experiments and procedures. Use scenarios - Chemistry experiments: securely hold a test tube or small flask on the bench during heating, cooling, or stirring to keep the setup stable and hands-free. - Electronics and materials testing: clamp capacitors or other components during assembly, inspection, or experimentation to maintain steady positioning and prevent damage. - Piston-related procedures: stabilize pistons or related instruments for precise measurement or observational tasks in experimental workflows.
